The girl here at Red Tractor farm goes to farmers markets , sells to local restaurants and operates a 25 family CSA in Albuquerque, NM . It gets hot here, today we expect temps to 100 degrees and our apricots are dropping like flies. The Coolbot walk-in, just completed this week, has saved our apricot crop. The coolbot is also a life saver in both time and angst about harvesting times. Now we can harvest more often and store easily and safely. And deliveries can be better coordinated and efficient In the past we depended on 3 old refrigs - yikes.
We used a tuff shed 8X12 with Polystrene foam board and spray foam in all cracks, for all walls and roof. After all insulation boards were hung on the walls, ceiling and floor, they were covered with plastic poly before installing FRP and insulated foil foam board. The ceiling has an extra inch of insulated foil foam board as ceiling cover and FRP on all walls. The floor was covered with insulated foil foam boards and covered with OSB and stick on tile. We purchased a GE AC 14000 AEL14AQ. next step is weather stripping around door, and it will even work better.
Brilliant invention! Thank YOU!

A Farmer video testimonial by Farmer Anton at Early Morning Farm. This was REALLY nice of him to make! PLEASE NOTE: Anton has been so very gracious to take the time to make this video we ask that you please do NOT call him directly for more information. He really says it all here, and there are too many thousands of people checking out CoolBot each year. It gets overwhelming when people are called... and I don't want him to make me take this down :-)
We are now chilling just-harvested vegetables to around 35 degrees Fahrenheit [obviously not when the door is open like this], where they are happier then they have ever been. We also dawdled around in the cooler for about 10 minutes after harvesting, we were so hot ourselves.

I just wanted to send you all this picture of one of your coolbots in action! We’ve got an awesome cooler set up now because of your generosity. Thanks for your help!

Our walk-in refrigerator has inner dimensions of 5' wide x 5.5' deep x 6.5" high and it keeps a constant 36F±1F. The walls are 2"x4" construction with R-19 insulation in the walls, floor and ceiling. I used a "Kill-A-Watt" meter and monitored it for 318 hours. This cold room uses 1857 KWH/year which is very reasonable in cost. Even with the very high electrical costs in Connecticut ($0.22/KWH), it cost us just $34/month for electricity for this cold room. Attached are photos.
We use it to store our garden produce and kitchen refrigerator overflow. Thanks so much for making the CoolBot, this cold room is wonderfully useful to us.
My parents and I recently ordered a CoolBot to create a walk-in cooler in our barn. We own a produce stand, so we use the cooler to store all of our extra produce. So far the CoolBot had been working wonderfully! We are able to get the temperature down to 41/42 degrees easily! Works better than we could have ever imagined!

I ended up installing an LG LW1015ER (10000BTU). Works great. I cut out the front grill and have it run on energy savings setting. No problems at all. The energy savings setting works great with proper insulation. I increased to an R40 value and the cost to run this set up is very minimal. I love the CoolBot! Thank you.

My name is Jim and I am located in Pennsylvania. I am writing this report for my Granddaughter who has a small organic farm. We bought the Coolbot on May 30,2015 and purchased the air conditioner on June 18, 2015. Installed it on June 19, 2015. Although we have it in the middle of the cooler and not on the end as suggested and we are undersized according to your suggestions It works very good. We set all the perimeters and turned it on, it was 72 deg. when started with set point at 40 deg. and in 1 1/2 hrs. it was down to 40 deg.
This Coolbot has performed far beyond my expectations and has continued to work great. I would recommend this product to anyone for it's ability to do what it claims and it's easy setup.
Thanks again for a great product.

Ok Katie here are the pics of my cooler. Well, I have had my CoolBot for around 4 years and just got it going. Just never had the funds to build a cooler, found a great deal on this 6 1/2 x 6 1/2 x 7 cooler. Put a GE 12000 btu cooler in it and watched the temp fall to about 37 deg. I love it.
Thanks for a great product, and the great user friendly directions. Thanks again and happy 4th of July to yall.
Joel H.| Texas
We just completed converting a 40' container into a cold storage unit next door to our fire station. It is a community garden that sells organic produce to the community. I came across the CoolBot after research on the internet. We split the container with 20' of cold storage and 20' of tool storage. I used the reference material found under your resource link.
I've included a few pictures...and as you can see it is cold! That picture was taken only about 30 minute into the cooling process and it was continuing to drop.
Thanks for all the help!
My CoolBot walk in fridge has been running for about a month now and it is awesome! The room is a little under 4' by 12'. I bought a 10k BTU GE air conditioner that brings the temp down to 37 degrees with no problem. As someone who likes to do things myself, I appreciate innovations that allow me to accomplish a project and produce a quality result.
Bill | Farmer in Oregon
I have a small apple orchard in Ontario and need cold storage for the apples from the time they are picked until they are sold, approximately 4 to 6 weeks each autumn. I have an insulated area that I usually use as a garage for my pick up truck. It is approximately 12 ‘ wide by 24’ long by 10’ high.
After getting a quote of $6,500 to supply and install a conventional refrigeration system, I decided to continue looking and found your add on the Internet. I checked out your site, including recommendations, how to install, and testimonials. I decided to give CoolBot a try.
I purchased a 24,000 BTU Haier AC unit from the supplier you suggested in Canada, and a CoolBot unit. After completing the required electrical, I installed the AC unit and the CoolBot unit and turned them on.
I had a little icing at first so I adjusted the fin setting to 2. The system has been able to maintain the temperature at 38 -39 degrees. Now that the weather has turned cooler it has dropped the temperature to 36- 37 degrees.
I am very satisfied with the CoolBot and what it has done for our apple storage needs. I have attached two photos of the AC and CoolBot in action. I read in your literature that you double the warranty on the CoolBot if a picture of the installation is sent to you. Hopefully, this will satisfy your requirements.
Thank you for developing such an amazing product.
Paul | Apple Orchard in Ontario, Canada
I'm "tickled pink"! :)
My total cost was about $900 and a lot of work for wiring and installing the A/C. The CoolBot solved a problem that I had been pondering for several years. Last year I called a refrigeration contractor but he never even bothered to return my calls – maybe he considered this job too small? I had seen my neighbor’s commercial refrigeration units and cold storage rooms and was envious but I could not afford to spend thousands of dollars just for our home-grown, and home-use vegetables. I found CoolBot using the internet search feature. Now we have a LARGE, walk-in refrigerator and can store foods from our garden and greenhouse – as well as other items that like to be refrigerated, like beer and cider! And, lucky for us, it’s downstairs in the basement so access during the winter will not require going outside.
Although it is not currently connected to our solar photo-voltaic system, it could be in a sustained contingency. We have 3 freezers and a refrigerator that are already connected to the solar PV system (with battery and generator backup). Now with the CoolBot we are feeling very secure and eating our own fresh produce! Thanks Ron and Katie and the folks at CoolBot!
I got my CoolBot this past week, I read the instructions and said to myself it can’t be this simple to install, well to my surprise it was. I have a 6X6 cooler box with 10000 btu window unit and 2 hours later it was at 38° with the r30 ridge foam insulation all the way around. Let run all night long and next morning all is still well. Glad I was able to find out about this product, I have pears and apples in it now all looks great.
Thanks for a great product

Here are some photos from a recent program conducted by HortCRSP and UCDavis working on a project to help provide cold storage to farmers in Honduras, India and Africa. These are pictures from construction in Aura, Uganda using two concentric mud brick walls separated by a 30 mm cavity that was filled with plastic bags filled with rice husks. You can read the rest of the article here
Here are photos from Dr. Neeru's project with Amity University in Noida, India in collaboration with UC Davis and HortCRSP. They worked on creating a cooler using low cost insulation technology. Using mud and rice husks for the walls, they were able to build a cooler that could keep crops cool improving post harvest quality which in turn creates more opportunities for jobs, education, and improved quality of life. To learn more read the whole article here.
Coolbot is truly a fantastic product! We are an organic berry farm from Canada and have chilled product right out of the field into the 6x8 cooler @ 34* F thanks to your engineering. Thanks for the quick shipping and detailed set up instructions!
Kenny | Canada
This is my installation in a root cellar. I was able to use a traditional root cellar with 4" pipe intake and exhaust for natural air which can be capped off when I want to cool it, as you can see down to at least 37 degrees. Because of space limitations, I had to put the air conditioner unit in the door, which complicated the construction somewhat. I also insulated the floor and half way up the side walls with 2 inch rigid foam R-10 insulation. The halfway up insulation allows the room to also function as a root cellar by acquiring ground temperature when I am not cooling. This combination allows for a broad range of uses. All CoolBot controls are set at the original default positions with no problems.
A Food Bank CoolBot Testimonial! What an AMAZING organization doing such terrific work! We got all enamored hearing about the organization and we cover the costs and CoolBot only at the end. This is a short two minute video of an INCREDIBLE woman doing incredible work. Again, please do NOT call Sara directly. She says it all here in this video and too many calls will force us to remove the link to this video.
On 5/4, I set the air cond. at 'cool' instead of 'energy saver'. And on CoolBot, 37 degrees [Ron snipped remainder of sentence]
On 5/15, Temp on digital thermometer in rear of cooler, reads 37.2 degrees
On 5/15, the usage for new settings for 11 days was 106 kwh - 9.6 kwh p/day. Cost at .13 per kwh comes to $39 per month.
In contrast, at 40 degrees at previous setting, it was using 3.5 kwh per day - .45 cent per day [Ron slightly edited this sentence for clarity]
In winter, usage is 1.3 kwh per day - will reset it to 37 degrees and 'energy saver' when cold weather arrives.
Sara | Runs a Food Bank in Ithaca, NY
(This is an email I got last year from Sara. Their cooler is 8x8. They are using a watt-meter on their CoolBot. Note the huge difference (from 45 cents per day to over 1 dollar per day just changing the temperature from 40 to 37. (there is another email about the previous use which I will also post somewhere here). This amount of energy use is pretty standard for a "conventional" walk-in at her use level, door openings account for a huge amount of energy use. At 40F, CoolBot systems are amazing in terms of electricity use. 36-38, we think we are pretty even. For people running 35 and lower, we don't have real-world data yet, but we THINK we are probably not as efficient! The CoolBot would still save you money in the short run, but in the long run, if you are always below 36F it will have higher electric operation costs.)
Thank you so much for designing the CoolBots! We purchased 3 last year for our CSA vegetable farm. We were able to build three 10 X 12 foot coolers for less than the cost of one commercial 10 X 10. They ran all summer and winter without a hitch. Our electric bill was also very reasonable. We had a rather hot summer here in Pennsylvania and they were able to keep our coolers down to 33 even when the temps were in the 90s. We used LG 24,000BTU units which held up well once we got a few kinks worked out. The support you gave trouble shooting the air conditioner issues I had initially was to seal it so we just leave it hang open and then everything works great. I just purchased another one since we decided to build a fourth cooler. It has been great to have enough cooler space to segregate our vegetables into ideal storage temperatures and humidity. We could never have afforded this much storage space with the price of other coolers. I tell everyone who will listen how great your design is!
Sara | Pennsylvania Farm
Just wanted to let you know of our success with your cool bot.
We purchased the cool bot from you in May of 09 and I built a 8X12 walk-in cooler to store all of our produce. I got the 12,000 btu LG air conditioner. We had a great first month and the I called you with problems with the cool bot sensor. You replaced that and we had no problems. The first LG was bad because the LED got wet and you said to replace the unit. I returned it in June and got new unit that preformed well all summer and fall. We currently are using the cooler to keep apples and eggs in it.
It has been -10 to -15 here, I have shut the ac unit off and am keeping the cooler at 37-40 degrees with a small heater.
I figure that we saved ~18-20 kilowatts per day this summer with the cool bot and ac unit. Great savings over the small floral cooler that we had in the past.
We have pictures of our installation on our blog spot that shows the cooler and ac/cool bot. That you can look at and use if you want.
Thanks for the great product.
Doug | Rolling Prairie Acres
It was very easy to set up and works great, a really innovative idea! I am a contractor who set it up for a client.
Nathan G | Charlotte, VT
A few weeks ago, an energy auditor from the Bonneville Power Administration visited our Co-op. He was seriously excited to find we had a Klimaire with a Coolbot for our walk-in. Apparently he had heard of Coolbot, but had been skeptical. Our "never above minimum rate" power bills on that meter impressed the Hell out of him!
If we had room, we could probably add another cooler to that meter, and still not increase our electric costs! Thought you'd enjoy hearing this. Our last challenge with the cooler was apparently due to old batteries in the Klimaire's remote control.
I hope you sell a million CoolBots. You've really done somethin'!
Al | Washington
Well it took a while to get it all done, but my walk in is up and running for a few months now and it's just great. I can get it down to 32F if I want with no problems at all. However I keep it at about 35 to 38. We are a small homestead and try to produce as much of our food as possible and also will be using the walk-in to hang our meat when we slaughter it. We tried for a few years to get away with just a cool room but we ended up throwing away a lot of our fruit and vegetables because we just couldn't get it cold enough early in the fall and then it would often freeze up in the winter. So far we've been really pleased and are already planning next year's crop knowing that we can now store it without fear of losing it because it just can't cool enough or cools too much. Oh and it's a great place to keep my homemade beer in as well.
This is a 4 by 8 room that's just off the milk room at the front of the barn. I had the room sprayed with 3 inches of foam when we initially built it as a cold storage, but I added another 2 inches of rigid foam on the inside, then put on cement board prior to finishing with ceramic tiles. The ceramic tiles really help to form a thermal mass and keep the fridge cool even after having the door opened for a while. The floor is also insulated the same way. The tile work is a bit much for a walk-in, but this was my first attempt at ceramic tiles and a friend who's a building contractor challenged me to a test of my skills by adding a diamond shaped border around the room so I took him up on it and there's the final results. It was good practice for when I tackle the kitchen and bathroom in the house.
Thanks for this great product. I have some hunter friends who are eyeing the fridge with a keen eye, so I'll be sending them your way.
Mitch C | Canada
The CoolBot and the LG 24,000 btu air conditioner are working like a champ!! We are keeping our 9 x 11 root cooler in our basement at 34 degrees!! That gives us 6 pallets of roots that we are distributing to our 80 member winter CSA. The cooling system has already paid for itself at this point. We are also benefiting from the exhaust heat from the air conditioner into the other side of our basement below our kitchen. Rarely do you get double duty out of a heating and cooling system like that. This system is great for our application.
Paul | Sweet Land Farm
We got our cooler up and going last night! We have a 24,000 Btu LG air conditioner in our 10x12 room, it went from 76 to 45 incredibly fast! This morning the produce was at 37! Our room is almost empty right now so we took your advice on reducing temperature swing and it seems to be holding its temperature now.
We built the ceiling & walls of 2x4s with 3-1/2 Styrofoam in the cavities. We sprayfoamed every gap we could get the nozzle into and then caulked every joint on both sides. Then we sheathed it with 2" of poly-iso insulation on both sides of the walls and again spray foamed every gap and caulked all the seams. For the floor we laid 2" of poly-iso down inside a 2x6 frame and then used joist hangers for 2x4s. We filled the cavities with 3-1/2" styrofoam Again we caulked every seam and sprayfoamed every gap on each layer before we sheathed the floor. If you can build a tighter box I don't know how. Our room used almost 4 cases of caulk and a dozen cans of sprayfoam.
We were worried the air conditioner would run non-stop, but this morning we timed it! It seems to be running less then 3 minutes about three times an hour, and that is with us peeking in all the time to check the temps!
The quote we got for a cooler this size with used wall panels and a new compressor was $12,000 not including delivery or installation. This unit cost us under $3,000 including the air conditioner ($600) and Cool bot. We did get a deal on recycled foam off craigs list which saved us some money.
We are very happy with our cooler! We are sure it will improve the quality of produce our 100 member CSA receives and help us expand next year!
Eric & Heather W.
[Note from Ron: I think this cooler has to about win the prize for most insulated and most tight. It's really impressive!!]
Love. The cooler is working excellently. But the Fin sensor got damaged with the sharp edges of the AC. I am using the spare. Can you send a few of them ? Can it be repaired here? I may ask my USA contact for the payment and delivery. A few pix are attached.
Annapurnananda | R.K.Mission, India
I built a 8x8 cooler, installed your extra-ordinary CoolBot with an A/C and boom! I got a real efficient cooler. Amazing! For a month and a half, 24/24, I kept the room around 37° easily and at the warmer period of the year. That was great. And I'd like to thank you for your help. Your article is very interesting, lots of informations. TY again.
PS: I talked about the CoolBot to a couple other small farm owners and they ordered one! :-)
Marc-Antoine | L'Héritage de MAÉLI, Quebec
We installed the Cool Bot and a LG 24,000 BTU a/c we got from Home Depot into our walk-in. It took less than and hour to drop the temp to 38 degrees. We did this in lieu of replacing our walk-in compressor. The fix was about 1/3 the cost and it seems to work fine.
Patrick M. | Houston, Texas
We found an old cooler box, foamed the cracks, and put it under a Carolina Carport. The CoolBot works great with our LG AC. Thanks for your unstinting help with my questions.
Great service! You guys are the best.
We have the coolbot up and running. I hate to sound melodramatic, but it is life changing! No more juggling space in the refrigerators, combining this and that. We have the temperature set for 42F (mostly squash and beans) and it has maintained a very constant 42-44 for four days. We inadvertently turned off the power for 7 hours. The temperature went up to 68 before we discovered it. It was back to 43 in 30 minutes!! That really surprised me- thought it would take hours. We are thoroughly enjoying our new cool room (especially on 96 degree days!). Is there anything else you need to know? Great article in Growing for Market. We both want to reread it and then might have 1 or 2 questions. Are you going to do any more post harvest articles for them? I think it should be a series. That is one area that is very lacking in information. When we go to Organic Growers Schools, etc., very rarely is that a subject.
>In this video, Farmer Paul take us on a tour of his cooler which he used insulated concrete forms (ICF) that he left empty so that it could be moved easily!
Ron Note: We visited Taos Pueblo in New Mexico and visited their incredible farm and were so excited to see that they used a CoolBot for their cooler! The whole place is a terrific model of practical sustainability and innovation. Like the greenhouse can be heated in multiple ways (including wood -- but SMART wood burning) as well as a solar hot air cycling system. Impressive place.
I just wanted to let you guys know we installed a CoolBot system at the Northern Neck Food Bank in White Stone, VA. The food bank serves about 4000 people a month and one of our most important goals is to raise the nutritional level of the food we distribute. Before we installed the cool-bot we stored all of our fresh produce in the warehouse. Unfortunately that means it lasted 24 hours at best, and we were throwing away hundreds of pounds of the most nutritious food available to us. Now we can safely store our produce long enough to meet the weekly distributions of our 24 pantries.
Thank you, your device has made a huge impact on the needy families in our community.
Director | Food Bank
To: ron at storeitcold
I want to thank you, My coolBot does what I needed it to do. I have a small produce shack that I sell goods out of to help with our SS retirement. I have built this stand and have had to buy ice to keep things cool. Now I can save $55.00 a week with your CoolBot. Here are some pictures.
The ac unit is in the bottom left corner the air moves through the bottom and up the right wall then falls down from the top.
[Note from Ron: Here is a person that is using a CoolBot in a way I doubted would work well. His implementation is so nice! I don't think it could be bigger than this AND please note that he's only set it to cool to 45 degrees... I REALLY can't believe it would cool into the 30's. Also, note this isn't a totally "open" display cooler as he is putting plastic over the opening in the front (I assume they are plastic strips, hard to tell from the picture). He seems like a gifted tinkerer/craftsman and not afraid to experiment - great combination! Now I want to do a display cooler like this for our farm!]
I've had the CoolBot about 2 months now and wanted to get back to you with a report. I have a 5' x 9' x 7' high walk-in cooler, and the CoolBot has made all the difference. My room has 4" foam insulation and is tightly sealed, and is cooled by a Samsung 10,500 BTU AC unit. For the first year I used my own micky mouse system, taping the Samsung's temp sensor to a "wall wart" power supply which would give off heat and force the temperature lower than the 64 degree lower limit on the AC unit. By covering the power supply with insulation I could force the unit to cool down to about 50 degrees, but any lower and it would freeze up. Still, I felt quite clever and believed I was squeezing all the cooling power possible out of the AC unit.
Then I heard about the CoolBot and immediately ordered and installed it. I have found it to work exactly as you claim. I can easily achieve 32 degrees in the cooler when the outside temps are 95+ degrees. And I love being able to set whatever temperature I want just by pushing a button, and knowing the cooler temp will stay right there. The CoolBot has made my "cool room" into an honest to goodness walk-in produce cooler.
Bill | Sunny Slope Orchard, Vacaville, CA
...we're running the cool bot and an LG 11,500 btu unit on 100% solar power and it works great. We maintain the walk-in at about 44 F. I'm not sure if there are other folks using alternative energy sources to operate a walk-in cooler? Our farm is off-grid and this was a great option for us as our below grade stone root cellar warms to around 58% at this time of year.
Steven S. | Hermit Creek Farm, High Bridge, WI
We love our CoolBot cooler- photos are on our website below- go down to May of 2008. The CoolBot system let us make a cooler out of an odd shaped unused shed on our packing house for about $2000 including some structural work on the building. It also let us keep the sight line the same on a property that's already crowded. It's about 6*8*6 interior dimensions and cools great with a 15000 BTU unit. It's really raised our productivity and produce quality. Instructions were great as well as the advice on how to build/insulate the cooler.
Couple of comments- A helpful addition to the website would be that most AC units go from 110 at 15000 BTU to 220 at 18000 BTU. For an older building like ours it was much easier to go down.
Also another problem we've had with our Samsung AC unit is that it won't reset itself if the power "flickers." No problem with the CoolBot, but the AC doesn't come back on with the power. Is this true on the LG's also? Not a problem now that we realized that it happens and added a wireless thermometer by the kitchen window so we can monitor the temps in the cooler.
[Note from Ron- LG Brand Air Conditioners (from Home Depot) do NOT need to be reset when there is a power failure. This is the one significant advantage of LG over Samsung]
I didn't think the frost control was needed until someone knocked the frost wire out and didn't replace it. AC was a sheet of frost but a couple of minutes of fan only cleaned it right up.
For the floor we used 4*6 rubber stall mats (from tractor supply in our area) on top of the two layers of blue board. It's made a nice walking surface and adds another inch of insulation.
Thanks so much

This thing is AMAZING! I'm just using an 8000 btu Samsung a/c I got for $200 from Lowe's and my room is staying steady at 42 degrees!
Tim | Farmer in North Carolina
We just installed the CoolBot in our newly built walk-in cooler. We are a mushroom farm that specializes in gourmet and wild mushrooms and we love the CoolBot! It saved us a lot of money compared to installing a drop-in refrigeration unit and it is simple to use. It works great, highly recommended.

Here are several photos of my finished trailer project using the CoolBot.
I purchased the trailer new and with the exception of some of the other purchased items everything else is my handy work (that’s me in a couple of the pictures, as if you hadn’t figure that out already).
We are an environmental consulting company, we do all types of environmental work all over the Country. I built this trailer for our Sediment Team which does their work on lakes, rivers, ponds and streams, any body of water where there may be a contamination problem with the soils and sediments at the base of the water column. The crew takes core samples of this material by several methods, those samples need to be kept cold until they are processed for shipment to the labs that we work with, hence the need for a refrigerated trailer.
We had been renting refrigerated trucks in the past but the cost has become prohibitive, so after a short presentation to our principals and VP’s I was given the go ahead and the funding to put this trailer together.
The trailer is now on a 3 month long sediment project site in downtown Chicago, late yesterday afternoon I received a phone call from one of our scientists on the project telling me that the trailer is working great and thanking me for putting it together as it is making his job and the jobs of his team much easier, a compliment well worth the effort, as are yours!
Have a great day!
Gordon P. | Milwaukee, WI
We have installed the Coolbot on a Dometic rooftop model and it has been working great for a couple of months. We love the system and surprise a lot of people when they asked how we did it.Cheers!
Shane |Brewery in Oregon
....fired it up set the CoolBot @5 degrees [41F] worked perfect and last season kept our flowers in perfect condition for our 55 weddings !! Set @5 degrees and worked perfect when the outside temperature was 48:-) [118F!]
So thanks for this great invention :-)
Gary | Florist in Spain
Hey Katie here is a few pics of my 8x8 cooler in the front of a moving van. All walls and floor are insulated with 4 inch insulation and polyed then sheeted with osb then covered with puck bourd. Hanging rails for hanging meat. I will certainly take the extra warranty that Ron spoke about on the phone if he is still making that offer.
First, let me say how impressed I am with the Coolbot. My daughter runs a food truck/catering business and needed additional mobile refrigeration for some of the bigger events/festivals she does. She talked me into to converting half a 6x12 utility trailer into a reefer unit using a Coolbot and a 15k BTU air conditioner. We finished it last weekend and have had it up and running since Wednesday at a festival and it's been hovering in getting 34-38F range. Fantastic!
Joel | Canada
We finished our trailer last week and it has been running at 40 degrees down to 36 degrees. We love it and will be using it for Farm to Market, Farm to Distributor deliveries and storage. We grow specialty lettuce in and Aquaponic Deep Water Culture System in a controlled environment greenhouse.
Mikey | Farmer in Texas
Here is a beautiful build of a mobile trailer being used for meat butchering, where Jeff has installed two 24,000 GE's each being controlled by a CoolBot.
Here is a 12'-2" Florida Gator 510 pound in the cooler I built with the GE 8000 btu a/c you recommended. It pulls it down to 39-40 with no problem for the 3 hour trip to the processors. Thank you,
Roland | Florida
Here is a CoolBot being used in a mobile cooler that was put up for sale on craigslist.com! Eric did a great job on this build. We used to have the link but this truck is off the market and has a new home. :)
Just wanted to let you now that the truck goes down to 38-40 degrees without much of a problem. The bigger windscreen is better for gas mileage. I went to a 4 foot windscreen gas mileage went up .5-1 mile per gallon more without cab a/c but with refrigerator running. Those delays on the heater really make a big difference of getting it colder without freezing up. I use a 45 second delay on both units and works great. Tried less but would freeze up so went back to 45 seconds.
Thanks for everything
Well, it took 3 years but i finally got it installed and working today. It's a bit of a weird installation - although I'm sure you've seen stranger. The pictures will explain it better than I can write - basically a frame with wheels that a "door"hangs from which has the air con mounted to it. I open the side door on my truck, wheel it over and (after a bit of heaving) it slots in and I plug in and i have a cool room! Just need to wheel it backwards in the morning, close the side door and drive off with the truck driven cooler taking over. Still a bit of work to do to seal around the door but it seems to be working fine!

As a deer hunter, the past few warm seasons have presented many challenges regarding maintaining quality meat. Our camp invested in a 12 x 7 x 7 freezer box and mounted on a trailer for mobility. We discovered 2 days before the season, that the ThermoKing unit on the box was going to cost a considerable amount to repair. It was a quick fix after a visit to the local Home Depot for a 18,000 BTU LG and a phone call to CoolBot to over night a unit. The next day, in 2 hours, we completed the install on our mobile cooler.
Temperatures averaged in the mid 60's during the day and we were able to maintain a constant 35 degree F in the cooler with 12 deer hanging.
Thank you for a great product and for your excellent customer support.

I am a small deer processor in NJ (150-200 deer a year). I have a 10x10x10 Walkin cooler that I built to hang and age deer in. It has a rolling rail and power winch in side and can accommodate approx. 20 deer at a time. The COOLBOT controls an 11,000 btu A/C unit and holds 34 deg even during the early season when outside temp is 85 deg. It is such an important part of my business. Thank You for your GREAT support.

I'm a professional kangaroo shooter in Western Australia. My son and I provide kangaroos to the local processor where the meat is sold mainly for pet food and the skins are sold to the leather trade. The profits are low so a cheaper alternative to commercial refrigeration was welcome news. At first I thought it was to good to be true but now I'm so glad I bought a coolbot off Ron and Katie. It was nice to deal with people rather than just a big company, I feel as the I've gained a coolbot plus two new friends. This gadget flamin rocks man. I have a 6 kW aircon in a 2.5x3meter cool room and it can pull 1 ton of hot meat down to 2degrees C in a matter of hours. It's as good as anyone could want. Five stars people!
I love clever people, they make my life better with inventions like the coolbot.

Hello, just received my CoolBot last week and finished bringing power to the walk-in cooler. I always wanted to have my own room to butcher my deer and pigs and now I finally do thanks to your company. The product worked just as I had read and maintained the room at 38 degrees when it was 95 degrees outside. Looking forward to years of processing my own animals.

This past fall I ordered your devise to control an A/C for a walk-in cooler I had bought to hang deer in that would be harvested in the PA Archery season. Our season has had rather warm weather which required us to quarter and place our deer in refrigerators. As you can expect not many deer fit in a refrigerator. Anyhow I just wanted to thank you and let you know that I have been very satisfied with your invention. My father was a farmer so I have roots in the farming life; I would also like to thank you for being a farmer. I have forwarded your email on to a friend that wants to purchase your devise, and I will continue to spread the word on your invention. All my friends are hunters and all have been impressed with how good the results have been. Many were very skeptical when they brought deer over, because of the temperatures they were afraid of a malfunction and loosing the meat. All are advocates of your devise and I am sure they will be spreading the word and maybe purchasing. I hope that this helps in marketing for you and lets you acknowledge that there is another market for your devise with the hunting world.
I just want to let you know how happy I am with the CoolBot product. I purchased a coolbot this summer and installed it in late July. First day I ran my system, it was 94 degrees outside. & I got my butcher shop / meat locker down to 50 degrees in less than 4 hours. I'm very happy with my butcher shop/ meat locker and the Coolbot was the icing on the cake. Simple installation and it's exactly what I needed to complement my Butcher shop/ meat locker. Thank You
I built my cool room and installed your computer system with the air conditioner you recommended. Within a 1 hr my room was down to 40 degrees where I set the computer and is staying there no matter what the temperature is outside. I am so impressed and so excited that I finally got my cool room. All my friends are so jealous that I have a cool room. This cool room computer is so great and so easy to install.
My room is 6 ft wide by 10 ft long and 8 ft high the air conditioner is a lg 15, 000 btu and will cool the room down to 38 degrees in no time. It works fantastic. Now my friends want to hang there deer in it also , of course for a small fee. I just want to Thank You for such a great product.
Gary G |Idaho
Ron, Well it's time for my yearly update about my cooler. This is the third season with the CoolBot and we are still loving it. We have three deer chilling right now and the cooler is working like a charm. I have every confidence that it will continue to be great for the remainder of the warm hunting season. I listed a few cooler notes and things that I have learned as over the past few seasons. Like CoolBot recommends the most important part of the build is making sure that you really make it as air tight as you can. I have had to go back through and fill areas that I found to be air leaks as it adversely effects the coolers ability to stay cool. If the cooler has a hard time maintain temp you can try lining the floor with foam and putting OSB or some other covering over the top of that to hold the cold air in. The CoolBot is the real deal and has really been a blessing. It has preformed flawlessly now going into it's 3rd season. Thanks again for making such a great product and i'll talk to ya next year for what I'm sure will be another happy update.
Cory |Walla Walla, WA
Attached are a couple of photos of the cooler I just completed. It is 6x10x7-6 made of two layers of 3” insulated metal panels with an 18k GE a/c, slightly oversized! The Coolbot has worked well on a couple of test runs, can’t wait to get some elk hanging for a good test. Easy install with clear instructions, I’m very impressed and will highly recommend your product to anyone interested.
Phil |Hunter in Washington
Installed the unit the same week it was delivered.end of July. Killed 3 hogs kept the room and pork at 36 deg. Room size 7 x 16 , 9 inches solid blue board walls and ceiling, 24,200 GE air conditioner. Near 45R factor walls . Today 4 more hogs , 37 Deg. no sweat !
I put your unit on a 12000 btu Lg. unit and it worked absolutely perfectly. This was one of the most enjoyable deer seasons I have had in seven years of processing due to your unit taking the early season pressure of warm weather off me. I had absolutely no problems at all and showed the CoolBot to many of my hunters. Many of them are now considering building their own coolers thanks to the CoolBot. I just wanted to say thank you for your help and for coming up with a outstanding product. I really appreciate it.
Richard Still | Owner Rick's Deer Processing
Just wanted to drop you a line and let you know I'm very happy with my Cool-Bot I purchased a few weeks ago . I built a 6x8x8 in my shop addition using 2x6 walls filled with rigid foam and wrapped with 8 mil. plastic. I used 7/8 plywood with 2" foam under it for the floor and built my own door out of 2x4s and full of rigid foam. I'm using a 10,000 BTU GE unit. I ran it before I had the door seals on it and kept it at 42 fairly well, (just wanted to try it out). Yesterday with the seals in place I did a 24 hour run with it set at 38 and experienced no problems at all, I opened the door a couple times and it recovered very quickly and had no icing actually I had no condensation drained from the unit either. There has been a lot of nay sayers since I said I was going to do this, I can't wait to let them know how nice it is to clean a cool dried out deer and not a warm slimy one. Thanx for a good product that was very easy to install with detailed instructions and all the info posted to build the cooler itself correctly
Mike | Ohio
The unit I have is a new amana ah183e35axaa less btu than you recommend ,inside dimensions are 8wx14'6" lx 9'4"tall .it would keep it at 45-47 degrees ,installed coolbot and it stays at 35 degrees with coolbot set on 37 degrees. Outside temps in 60-65 during day.Cheers!

Whom It May Concern:
Just wanted to drop you a line. I installed the CoolBot unit in my homemade Walk-in cooler. I purchased all the supplies to make an 8 by 8 from Home Depot. I purchased the air conditioner unit from Circuit City. Totally I have approx 15 hours in design and installation. The total price was under $1400.00 which is a huge difference from $5k I was quoted for the same size cooler. It has worked flawlessly since the time I turned it on. If you ever have anyone skeptical of your product, feel free to forward this email to them. It only took minutes to install and I'm 100% satisfied!
Everyone that sees it is highly impressed. My sole purpose is to use the cooler to hang deer in. I'm in charge of a D-map program (the county allows me to harvest as many deer as possible in the month of Sept, deer are destroying local farmers crop). This Sept in Northern VA the weather averaged in the 80 degree range. Without the cooler I was out of luck.
Also, bow season starts this Saturday and the temp is suppose to be over 80, my family and friends wouldn't be able to hunt without a place to hang the deer. We are very responsible hunters, we eat deer meat twice a week and give the rest to needy families!
Thanks to the CoolBot, I have no worries! Great Product! Please give my comments to the developer! Awesome!
Samuel R. | Marshall, VA
Hello just to let you know that the coolbot that I purchased is terrific. I got a bull elk on the 18th of September, so it is still quite warm out. Having built the cooler throughout the summer I finally had a chance to test it out. WOW !!! I hung the quarters in the cooler, and turned the coolbot on with the A/C unit. It took about a half an hour to get to temperature which was 2.5 Degrees Celcius and held there. This was with a (+ or –) of .2 degrees and the humidity was at 82 to 85%. Just perfect for hanging wild meat. The animal was in the cooler for 14 days and turned out perfectly.
The cooler is 12 x 6.5 x 7.5 feet in size and the A/C is a Danby 12,000 BTU. The coolbot was very easy to set up and the instructions made setting the unit a breeze. Every early season hunter should invest in this great little tool.Thanks
Tim M. |Canada
Hello last winter I bought a coolbot from you, talked to you a few times on the phone. This is my Davey Jones locker, 6x7 enuff hooks to hang 2 deer quartered out.
This deer cooler was built for short term deer carcass storage (one week maximum) a few times per deer season in Western Kentucky. The heat is pretty extreme during the archery season which always begins the first Saturday of September. Also, the processor that we use is Amish and they will not take deer in on Sundays. Therefore, we had issues with Saturday evening hunts and especially with Sunday hunts. Now with the CoolBot – we no longer have any Sunday restrictions due to lack of deer cooler to take our deer to for storage!
I tested the unit initially at my home in Georgia last week and then again at my farm in Kentucky this past weekend. I have to tell you that it works exceptionally well and the temperature stayed right on target much better than I could have imagined. I set the CoolBot for 40 degrees F and monitored the actual interior temperature with a digital remote thermometer. The temperature stayed at 40 F most of the time and dipped to 39 F every so often (I am sure that is due to the cycling of the AC unit). Cool down time for the box was 30 minutes at most and the ambient temperature was just under 85 F on both testing sessions. I am an engineer and really appreciate the CoolBot's simple design and operation. Great design, most excellent customer service with all questions answered promptly and most importantly an obstacle removed with the ability to store deer carcasses right at the farm in Kentucky!
Thanks again for all your help and guidance with the design!
Bob | Deer Processor in Georgia
This was a commercial cooler at a grocery store and I reconfigured it into a cooler and room to cut meat. The cooler itself is now 8x10 with galvanized steel walls.

Hi Guys I have built a 54inch x 90 inch, eight foot high meat cooler using your cool bot and a 1200 btu Haier a/c unit It works just wonderfully (but I wish I knew that putting the a/c unit high was the way to go). Even so with the thing about two foot off the floor it still seems very good. I used 2x6 construction, r22 fibreglass insulation all round including floor with OSB protecting that and an additional 2 inch styrofoam board r10, with again 3/8 osb protecting that all round. Overkill maybe but the temperature comes down really fast and holds at the setting without the A/c unit kicking in and out. I am very pleased so far and can hardly wait to hang the next game animal, it should really take the panic out of preparing it for the table. Just need to convince my wife that she can’t put her garden veggies in it.
Hi! Stanley F. in McConnellsburg Pa. Here is my home made cooler 8x12 with 18'500 btu comfort air unit with auto restart. Was 57 inside and took 4 min's to cool down to 40 and shut down compressor. I like it. Thanks
Stanley F. | Pennsylvania
It has been several months since I purchased the Coolbot and I am very happy with the performance of it. My dad constructed a 5 X 10 cooler inside his garage for our butchering. ...we insulated very well, it performs perfectly. We set the temperature to 36 and the Coolbot maintains that very well except when we are in and out of the cooler many times. I knew this would happen because of the upfront information you provide on your site. At those times the temperature only rises to 40 degrees and that is very much acceptable. The Coolbot has made it possible for us to do what we love for a fraction of the cost. Much thanks.
JD | Butcher
Attached is our completed CoolBot Shed. We are using the 12,000 btu Danby air conditioner. We use it for aging our venison and it works great. The room is 4' x 8' and it cools down immediately and maintains the temperature. Great product!
Frank | Hunter
Hi guys, we bought our coolbot on 9-25-14 and love it. We have hung deer in it so far, and will use it for lamb in a couple weeks. This is for our home butcher shop. We are looking forward to using it for beef and pork next year as well. Thank you very much for inventing and selling this product. (and for doubling our warranty as well)
Jason and Maria | Washington
We really like the way that the coolbot works. The cooler is 7' x 10' we installed a 10,000 btu LG ; I know that you don't approve of this brand it was the only kind we could find this time of year. We set the coolbot on 40% and it only took 15 min to get from 64% to 40%. I ran it for three days with a deer hanging and it never missed a bet.
Dale H. | Kansas
I finished the installation of a 12k BTU GE, Model AEM12AS Air Conditioner and your CoolBot as you recommended. Wow! Temp inside cooler went from 73 degrees to 34 degrees in 44 minutes! Thanks for a great product.
Roy | Alabama
Update: I finally got my deer cooler constructed enough to install the AC unit and CoolBot. I had to change some wiring in the subpanel in my garage and finished last night. I followed the CoolBot instructions and powered it on. The temperature inside the cooler was 59 degrees F when the CoolBot and LG unit started. In about 16-17 minutes, the temperature dropped to 39 degrees F! Nice!!! The CoolBot had been set to 38 degrees F.
I am writing this to show you our building process for our walk in deer cooler, I read in the installation instructions that if we supplied you with photos of our coolbot, that you would double the warranty on the unit.
We built a 9 X 9 cooler.
We poured a cement pad with a drain.
We then framed in the walls, and roof, we installed siding, and insulated the walls....
One of our friends acquired a cooler door, and we framed it into the opening for our cooler!
Our test run got the room down to 39 degrees, much to our liking.
On Sep. 24th, I was able to christen the room with our first deer, and the coolbot is working excellently!
We even took it one step further, and installed a Quirky Wink Spotter Sensor, that will give us notifications if the temp goes above a certain temp, so we know that something happened to the unit, so we don't lose any of our precious venison! Guess you could call us high tech rednecks!
Thanks Coolbot! We hope to get many years of use out of our new cooler!
Our walk in cooler project was in the back section of a shipping container. using ridged foam insulation. Our meat was in a temperature staying between 34 - 37, depending on how often we opened the door. The a/c hardly ran and I set the fan to the lowest setting as the highest setting took it to 28! Just an amazing piece of technology. CoolBot (walk-in cooler controller) . We installed it in minutes, it works amazingly well for a walk in meat cooler. Deer next!
Highly recommend this product.
Raised From the Bed Farms
I have been wanting to put together a small walkin cooler to hang deer in. After researching I found out about your coolbot. I found a 6'x6' walkin cooler box. I put the cooler together in my work shop. I installed a G.E. 10,000 btu a/c and your coolbot. This system works fantastic. I set the temp. to 38 degrees and it takes about 35 minutes to reach it. I could not be happier.Thanks for a great product.
Just wanted to let you know that we've been using our walk-in cooler for about 2 months now (mostly for storing beef), and it's been serving us well.
We have a Samsung AS12UUPX (12K BTU) split-unit AC cooling a room of about 10 feet (L) x 6 (W) x 8 (H). We used 4-inch Styrofoam insulation all around, save for the door, which has double insulation because it faces the morning sun. We converted an old bathroom which had tiled floors as well as walls.
Total cost was around 40,000 Ethiopian birr, which amounts to a little over $2,000. Could've done it a bit cheaper were it not for the fact that the AC cost three times (?) more than it does in the US.
Really excited about expanding the use of this technology in Ethiopia.
Mathews T.| Ethiopia
I've attached a few photos of our newly constructed cooler using your CoolBot controller.
We used the University of Kentucky version on your web site with your couple of suggestions regarding rigid foam on the inside.
The floor is 5 1/2" rigid foam with 3/4 ext ply wood (2 layers on top) sandwiching the foam with no framing.
The cooler is 8'x8' with a 12000 btu LG air conditioner. We built it inside a barn that we did insulate the roof structure of the barn above the cooler with fiberglass insulation.
The cooler went from 70 degrees or so to 37 degrees (the temp we set in the CoolBot) within 1 hour 30 minutes. It really was about an hour but I wanted to give you a conservative number.
We are not quite done, but as you can see from the photos we got her going to hang our hog. Need a bit more work on the inside including permanent electric with more meat hanging poles and some trim. We may also hinge the door in the near future.
Tom K. | California
Hey Gang ....
Awesome product. I had a old 8 x 8 ft shed, that was not being used. Bought a 12,000 BTU LG air conditioner ($319.00) from H.D. - insulated as instructed by your web site (did not insulate the wood floor). CoolBot arrived in the mail at 1:00pm. It was installed in minutes, and by 3:00 pm, I was at 33 deg.
Opened the door to take a picture - it jumped up a degree. This room will be used to age deer, and keep meat cool and firm while making sausage.
thanks for a truly great product!!
[Ron's note: This is a great letter, and I HAD to include it in the testimonials page!!! But this is not normal, actually... I think this just happened because the room was completely empty -- so it makes us look better than we are... But we are still AWESOME! It's just that empty room... you are just cooling the "air" so it can appear to be much colder than any product IN the room would actually be. If there was a thermometer in something with more weight than air (like a glass of water) then I bet that would have just been 37-38F. Check out our air conditioner sizing page for more information.]
Up and running!! Works great. Already have game hanging. Thank you so much for your help , you people are great!!
Kelvin K. | British Columbia, Canada
Just to let you know that the new settings you sent me worked like a charm. Now that I know my 8,000 btu will work, I will proceed with proper insulating (all styrofoam) and get ready for next year. We had a heat wave here (at least by our standards for late September), 70 F in the shade. The cooler fluctuated from 39 F to 42, depending on the particular day. Fantastic !! I don't know if I'm the only one who has tried the 8,000 btu unit (smaller than recommended) but if I am, you can tell them it definitely works for hanging game. Obviously the 11,000 or 12,000 is the better choice and I will eventually go to that anyway but for now, this works.
Dale A. | Staffing & Training Officer - Fish & Wildlife Division
After much reading about the Coolbot I bought one and put in my walk in cooler. Waiting on my first deer kill of the season to put it to use. Had a small problem with the installation but got them on the phone pretty quick and they helped me with the problem. Had very fast shipping very nice people to work with. Would recommend to anyone.
I purchased a CoolBot from you last summer. I built a 4x4x7 cooler to hang deer in during the hunting season. This unit is the easiest to install and works beautifully.
I am a licensed refrigeration technician and I couldn't have built this any cheaper or easier if I tried. It worked flawlessly last deer season and I couldn't be happier with your product.
[Ron note: We had to remove the picture of the deer, that's why this image looks odd]
I built my own walk-in cooler 8x8x5. Insulated with 4" of foam board insulation. Siliconed and sprayed insulation on all open areas. Installed an LG a/c unit 8000 btu capacity. It's been operational now for 1 week but so far it works great! My walk-in cooler, as you can see, is inside my barn located in the North Country, central New York state. The box reached temperature down to 38degrees w/in several hours. Great product so far!
Thank you very much!

I was skeptical but was building a walk in cooler for meat storage and aging and I stumbled across your website while looking for a refrigeration unit. After much debate I purchased a CoolBot versus the cost of a typical walk in refrigeration unit. It does work so I wanted to share my story. Your website contained lots of useful common sense information both the good and the bad and that along with the testimonials is what sold me. I may get a little long winded here but perhaps this may help others down the road.
I needed a small walk in cooler to chill a couple deer or an elk every now and then. The inside dimensions are 4' by 6.5' by 6.5'. It is built inside the back of my garage, with the garage back wall being the back wall of the walk in. I bought a 10,000 BTU LG AC unit per your recommendations. I had access to tons of free foam insulation and siding materials left over and headed for the trash from a construction project. I have 4 inches of the yellow foam covered with plywood for the floor. The walls and home made door have 7.5 inches of white foam insulation. The ceiling has 9 inches total foam (4 yellow and 5 white). I paneled the interior with the 1/8 inch hard board type stuff just to keep an elbow or deer leg from going into the foam. Exterior is covered with hardy plank siding.
Also as the pictures show I mounted the CoolBot on the exterior of the walk in. That was by design because with animals in it I didn't want to have to be opening the door and losing the cool to see what it was doing. I plan to put meat in it and leave it be until butchering time comes along. I also added a fairly inexpensive indoor/outdoor wireless thermometer as a backup check on the interior temperature.
Here are the results of my first test run on an 83 degree (inside the garage) Arizona day:
Walk in interior temp was 81 degrees at turn on. CoolBot set at 33 degrees (not that I need that for aging meat, but just to see what it would do). AC unit set at 60 and on medium fan speed.
[**Ron's NOTE: We normally encourage people to do high fan, but he has a larger air conditioner than we recommend, and the room was empty, so it doesn't matter in this case, plus his insulation is AWESOME!]
In one hour room temp was at 40 degrees.
In two hours room was at 37 degrees.
In four hours room was at 35 degrees.
In six hours it hit 33 degrees. Remote thermometer mounted by door said 33.9 degrees. At that point I opened the door and shot the room with a temp gun for a third check on things. The floor was 31 degrees and the walls were 32 to 33 degrees. The AC unit looked fine.
At that point I turned it off had a beer and called it good.
Cliff P | Mayer, AZ
The building, cool bot, ac unit and all only cost me about $800! [In a]8 x10 building, 4 x 8 is the cooler. I sprayed the walls with 45 cans of great stuff from Lowe's. 3 1/2 inches thick between the studs. Closed the walls in with plywood and covered with linoleum. Didn't stay cool enough. Added 1/2 inch foam board to all the walls and the cooler got down to 35 degrees. Very pleased with this first run of the cooler.
Thank you again,
Ron- I just wanted to thank you for the quick response! I took a gamble, and installed the ac [Ron's Note: We were worried about an old Maytag he had that was digital but a questionable entity]
boy am i glad i did! we had the cooler down to 37 degrees in just 24 minutes!!!! (it started at 74).. 1.54 degrees a minute is way more than i expected, so thats great.
thanks again for the help, and you now have a testimonial that Maytag AC's do in fact work!
Just shot 2 deer this morning, so the cooler is getting its first real test as we speak!
thanks and take care
I wanted to send you a note to tell you how pleased I am with the CoolBot. I think I bought it from you in 2008. I built a cooler that is 7 ft. long by 6 ft high by 4.5 ft wide. Power it with a 8000 btu LG Air Conditioner from Home Depot. I have hung deer, moose and elk in it it the fall and keep cherries cool in the summer.
It works fabulously. I am trying to keep it somewhat of a secret that I have a cooler or during hunting season I know there will be a line-up of trucks in front of my house with deer ready to hang.
Gary T. | Kelowna BC, Canada
Just wanted to share some details and photos of my walk-in cooler:
4" concrete slab
stud walls with OSB board on outside covered with tin siding
7 1/2" of Styrofoam insulation on walls and floor covered with OSB board and painted
insulated metal door
4" sandwich roof panels
interior free standing hanger frame
used an LG 15,000 BTU air conditioner
Exterior of unit is 8 ft by 8 ft
Thanks for your website instructions..
Kenneth S | Gerald, MO
I have to say that I'm extremely impressed with this little machine. I installed it on a 8000 btu maytag air conditioner and put it in my current small meat hanging room (4' x 6' x 7.6' h) which is far from insulated proper to try the unit out. After 2 weeks of checking morn & nite temperatures finding the unit only moved 3 degrees (40 to 43) even when the temps jumped to 90-95 outside.At current we are redoing the meat room over to proper insulation standards. I personally would recommend this COOLBOT unit to everyone who is considering a walkin cooler. Can't wait to try the FREEZEBOT!

[Ron's Note: Provided non-metric conversion for US folks]
We had great success with the coolbot! Our weather was warm to start the hunting season so it was imperative it worked for us and boy did it. We had to make some adjustments for the freeze up but moving the fins setting to 2 and the heater delay to d3 made it work like a charm. It kept the small cooler, 4x10 ft to at or under 40 degrees for 10 days. We hung 2 antelope, 3 cow elk and 2 mule deer bucks and the coolbot worked perfectly.
Thanks for the help and the great service on timely shipping.
"My Redneck Cooler"
I finally got the cooler put together and the AC and Cold bot installed. The cooler is made from old cooler panels that were left out in the rain and cold for 4 or 5 years. They had water loged froze and swole up. The cooler is 8 x 7.5. The AC is a LG 18,000 BTU. It was 66 deg when we turned it on and it went to 38Deg in about 15-20 min. I still need to fill some cracks etc.
Im sending a before picture and it looks pretty rough. I will send and after picture when I paint it.
Melvin T. | Washington, Georgia
We used it to put our deer in. It got down between 35 to 37 degrees. They was asking 3 to 4 thousand dollars for an outside and inside cooling unit. With the CoolBot and ac it only cost us 700 dollars.
For several years now I have been wanting a walk-in cooler but they were way out of my price range especially since the only thing I wanted it for was to hang deer in the fall. It turns out a couple of weeks ago I was online looking for some sort of refrigeration unit for sale so that I could maybe build my own cooler and thats how I found the CoolBot.
I proceeded to clear out a corner of my detached garage and built a 6' X 8' cooler which has 4" foam board insulation on floor, ceiling, and walls. I'm cooling it with a LG 10,000 BTU unit and have no problem keeping the cooler in the mid to upper 30 degree range. I wanted to let you know that I am completely satisfied with the CoolBot, it works perfectly just as claimed and couldn't be any easier to install and operate.
I start Bow hunting for deer in September, and here in Kansas there has been many deer I have passed up, or just stayed home due to the temps being too high. But now that will no longer be a factor, not with the CoolBot, so thanks for making that possible.
Richard F. | Stilwell, KS
Thank you for your quick response and concern when our new cool-bot showed an error read on the defrost sensor. Since we reinstalled the new cool-bot it has worked flawlessly as advertised. It is much quicker to defrost than the original one purchased and the unit is only running about half as much. We are using an LG 10,000 BTU unit to cool down below 40 degrees a 4 by 8 cooler room. Although not necessary we have had it down to 33 degrees, I cannot believe how efficient this system is and how much better it cools than our old system did.
Thanks for a great product and for excellent customer service!

Beer and Brewing Coolers
It took a while to get everything up and running but I made it. The fact is, one can do anything in Mexico...it just takes more time! The cooler is constructed in our lower level brewery addition. I was able to find 4' X 8' by 4" foam panels in Puerto Vallarta for about $13.20 US each. I framed the room with 2X4's on a 48" spacing. The floor is also 4" foam with 2 layers of 5/8" particle board on top, ceiling is 5" of foam. I wrapped the outside with 5/16" paneling and painted it. Inside is just foam. I covered all the exposed studs and caulked and taped the heck out of it. I lucked out on the door and hardware, it is from a commercial walkin. I found it on Craigs List for $50.00 a couple of years ago. The cooler measures 6' X 12' interior. I'm using a Haier 12K BTU AC unit. It ain't pretty..but it sure works!
Had an ice problem at first but then just followed your clear/concise instructions and moved the "fin" sensor down, That cured it.
When fermenting ales, I just unplug the BOT and move the bundled sensors back up against the fins and hold my 72 degree temp just fine on the AC thermostat.
When crash chilling after fermentation, for brewing Lagers and for carbonating the finished kegs I just drop the sensors back down and plug the BOT back in. I am able to hold 35-40 degrees easily while running in econo mode. Unit cycles on for about 5 minutes every 30-45 minutes depending on how often I open the door.
I can't say enough about what a jewel this product is! With the emerging Nano-Micro brewing revolution under way here in Mexico, I would think you have a heck of a potential market here!
Thanks again for a great product!

Here is another awesome video testimonial from a The Rhinehouse bar in Ithaca New, York. Built with used cooler panels from a grocery store, this 18 foot long keg cooler cost only $2000 total. This short 2 minute interview touches on the low cost build and the ease of maintenance.
Houston... We have lift off. Down to 35 and dropping. Thank you for your amazing customer service. I'll spread the word.

Here is our second walk in for our brewery. Took two days to build, cost about $2800 with labor and AC. Keeping the new 6x14 room at 38. Only took 40 minutes to drop it from 70 to 38!
Josh, The Big Rip Brewing Co.| Missouri
Started the cooler up about a month ago. Has been holding 38 degrees great
Roger | Brewery in Colorado
Here are a few photos of my cooler. It is a pantry next to my kitchen (4.5' x 5.5'). The air conditioner exits into my garage. With a little work and the CoolBot, I have what I believe is the perfect setup to fermenting my beer.
Cheers to all the fine people at Store It Cold.
Jim S. | Home Brewer in Oklahoma
Just wanted to say thanks for the help on this. We got our CoolBot and AC up and running very quickly and it's been keeping temps around 38 degrees for a week or so.
Steve S. | Brewery in Massachusetts
Just installed my second unit. First one for a walk in. This time it's in a beer cooler I made. It was installed in ten minutes and cold in less than that. Thanks again.
Hi Katie - all good now with door properly sealed. The Coolbot is happy and I am looking forward to serving cold beer! Thanks,
Lance | Bar and Brewery in St. Francis, South Africa
I certainly do not write many reviews but I simply must with this experience. The compressor died on our WIC with a whole lot of beer within. I had been thinking of a CoolBot and when I called, Katie answered and worked out a solution with me. She was awesome. It was late on a Friday and I received the unit on the Tuesday afternoon on a LONG weekend in Canada. The unit was in service in no time and appears to be working fabulously. Thanks Katie, you and your CoolBot rock!

Pictures from Economy Coolers. They sell pre-made cooler boxes already outfitted with CoolBots and air conditioners in Tennessee. Contact Richard Finchum (call 615-417-0637) for more information if you want to buy a ready-made system. He says their beer coolers outfitted with CoolBots keep the coldest beer in the state of Tennessee!
Here are photos of the Brewsters Draft House store# 9. We built this and used FRP as cladding both inside and out. We used a 24,000 BTU aircon from GE with your coolbot. Known for the coldest draft beer in town.

We duplicated this walk in cooler draft box from Brewsters first store. Used same 24.000 BTU aircon using your Coolbot. We covered this one inside out with FRP and then added a wood exterior for a comfortable woodsy look.

Here's the CoolBot set up and ready to go....It has worked as promised so far. Thanks for such a genius, yet simple product. Wish I had thought of that.
Kirk | Cidery Owner in Virginia
I saw your post on the BA Forum about CoolBot. We’ve been using the product in our business since we opened last August. I can speak to the good and bad, as we’ve had to deal with some issues that are now (finally) resolved.
First up, I know a number of brewers in the Denver area who use CoolBots and love them.
So, about our cold room. We converted an old AT&T store to be a Colorado Craft Beer Tap House. We have 30 draft lines. Immediately behind the main “store” area was a storage room, basically 6 ft wide and 15 feet long with a 10ft high ceiling. We wanted to drop the ceiling to 8 feet (to give us less volume to cool) but the City wouldn't let us without completely re-doing our sprinkler systems. We took this room and stripped drywall off all the interior surfaces then filled the walls and ceilings with rigid insulation. Filling in the stud walls we probably have a bit over 3” in the walls (we wanted 4”) and about 6" in the ceiling. Our construction specs called for the walls to be filled with spray foam but we had some code issues and had to use the rigid. The walls and ceiling then have plywood sheathing and are covered with FRP panels. The floor is bare slab concrete. Inside the cold room we have 30 kegs (1/6, 1/4, and 1/2 bbls) along the long walls on “double stack” keg shelving and another 6-8 “backups” on keg dollies between the shelves. We have a cold room curtain over the door opening. The door is steel - insulated, but not a true “cold room” door.
The doorway is at the end of one of the 15 ft walls. As you stand in the doorway, there is a 6 ft wall to your right. This is a common wall with our neighboring business. Ahead of you is a 15 ft wall with the keg shelving. We havea direct draw system, so there is an uninsulated “window” roughly 1 ft tall x 10 ft long for the shanks and faucets. The only separation between the cold room and the bar area (in this window) is the stainless steel tap wall. On the left end of the room is the other 6 ft wall which backs the hallway from our bar area to the bathrooms. Along the door wall is more keg shelving (to your left as you look around the room). One other note: the door wall backs to an interior hallway that leads to our storage area.
As we planned the space, we were limited in where we could place the CoolBot and A/C unit. One 6 ft wall was out because it is a common wall with our neighbor. The other was out because it would exhaust into our customer area (and directly over the thermostat for our entire space). One 15 ft wall was out because it would require the backside of the A/C unit to be right above our bar - ugly, noisy, and heat producing. So, we had one option which was to put the unit on the remaining 15 ft wall. We did the calculations, upsized slightly, and installed a 24,000 btu GE unit directly above our door, because that would mean it would vent into the storage hallway. I didn’t consult with the folks at CoolBot about our plans before we installed everything.
For the next several months we struggled trying to get our cold room temp below 40 degrees. Measuring beer temp at the glass, we were around 43 degrees. As you can imagine, we had lots of foam issues. We also had frequent icing on the face of the A/C unit. We installed a few “desktop” fans in the cold room to move air about. That took care of most of the icing issues, but we still couldn’t get the temps where we needed them. I spoke with Ron at CoolBot a few times to see what he recommended. His feeling was that the problems we were encountering were caused but the placement of our unit. Ideally it should have been placed on a short wall so that it would blow the length of the room. By placing it on the long wall, in the corner, it was blowing straight across the short dimension and the “bounce back” was causing the icing. The fans took care of most of that, but we still weren’t getting enough cooling efficiency to get the temps down.
By the way, I wish that every business I deal with had the level of customer service that CoolBot provides.
My next step was to contact a commercial refrigeration company to see if they had any suggestions. First, they confirmed everything that Ron had told me. They also said that using a CoolBot made a lot of sense (even thought they had never seen one). They investigated our space to see if it would be possible to install a “real” cooling unit in the ceiling of our cold room. Initially they felt it could be done (at a cost of $5000 - $7000). After more investigation they found that the configuration of our ceiling and the wall structure would make it very difficult (if not impossible) to install a unit. The quoted me a price of $10,000 to $12,000 - and I would need to take care of electrical work, dismantling the drop ceiling over our bar area, and then rebuilding the ceiling.
So, I went back to Ron at CoolBot. His first thought was to remove the unit we have, fill the hole, and reinstall it in the 6ft wall that backs to the bathroom hallway. We talked about the issues it would cause - heat and noise - and that it would wreak havoc with our thermostat. Then we talked about moving the unit further down on the 15 ft wall (where it is). In this location it would create heat and noise across from the bathroom doors, but we could live with that. We would be looking at about $1000 in costs for construction and electrical work. We also talked about installing a smaller second unit, but the saving would only be about $100. At that point we decided to install a second 24,000 btu unit across from the bathrooms (where we thought about moving the existing one). Since we didn’t have to fill and insulate the original hole, our construction and electrical costs dropped to $800. With a $450 A/C unit and a $399 CoolBot, total cost to install the second unit was about $1650. With two 24,000 btu units each works a little less, and we basically have a backup if one goes down - temps would go up a little, but it would be far better than not having any cooling.
So, we went ahead and installed the second unit. Right before turning it on, I checked temp in a cup of water I keep in the cold room (39.7 degrees) and at a served glass (43 degrees). 24 hours later, with both units running, I measured 35.2 degrees in the cold room water cup and 38.1 degrees in a served glass. We’ve been running this way for a bit over a month now. Temperatures have consistently measured at 35 inside and 38 at serving. The CoolBot over the door (the original unit) shows 37-39 degrees on its display. The new unit shows a fairly constant 35 degrees. Our foaming issues have pretty much disappeared.
We measure “efficiency” on our kegs - how much of each keg we actually sell - and we’ve seen the numbers go from the high 80s to the mid-upper 90s. There are lot of reasons for not reaching 100% (foam, waste, sampling, etc), but a 1% improvement in efficiency gives us a bit over one more pint to sell from each keg. At our current sales volume that equates to about $200 in added revenue per month. If we can see a 5% improvement, then our $1650 investment would yield an annual $12,000 in extra revenue. There is some additional electrical expense, but I can’t say for sure how much (yet). Our most recent electric bill was up about $85 from the previous month, but the weather was a lot hotter and we also installed a new beer fridge.
So, here are a few things I would say about using a CoolBot unit:
- Put as much insulation as you can into your cold room.
- Do all the calculations for your space (on the CoolBot website) before you size your unit. Then do them again.
- Try to install your unit so that the airflow disperses as well as possible. You have a square room, so having it up high in the middle of “any” wall should be good.
- Email Ron at CoolBot (email@example.com) if you have any questions or just want to make sure you’re planning correctly. I probably would have saved a lot of headaches if I ran things past him BEFORE I installed the first unit.
- Clean the A/C unit fins - both inside and out - every couple of weeks. If they get dirty, you will see a LOT of ice form. We use a fingernail brush on the fins. It takes longer to move the ladder than to clean the fins.
- If you’re venting into an inside area, be prepared to deal with condensation. We have to keep a bucket under our “original” unit due to condensation. The newer unit doesn’t create as much condensation, but we still defrost it monthly and get rid of any condensation that has built up.
- Work with a good contractor who understands your business. Our guy was a good commercial builder, but he didn’t know enough about cold rooms to be able to help.
We are really happy now with the CoolBot, and our total investment is about $2500 for the two units including construction and electrical. We’ve saved a lot of money vs a commercial unit (which we later found out we probably couldn’t have done anyway).
Hope this all helps you in your decision. It was a lot to remember and type up, but its good for me since I now have it all pretty well documented!

We are a Liquor, Beer, & Wine retail store in Blackwell, TX. CoolBot has been running for over seven months, and we are loving it. Our walk-in cooler is located in the inside of our store.
After comparing prices of manufactured walk-in cooler online, I decided to google homemade walk-in cooler. I came upon your site - TADA! All we had to do is build our own cooler, buy an AC Unit, and CoolBot. We read through your all of your notes and article links. We took most of your advice on building our cooler 8'x10', and discussed whether or not to used fiberglass insulation at all. Since we're a package store and all our products going to be dry, we went ahead and decided to use the R-13 fiberglass and 3/4" Polyisocyanurate Insulated Sheathing insulation in our walls. This is our specs on our walk-in cooler
[Removed for space]
We had a lot of positive response about our CoolBot Cooler
Lynn (and Billy, Robert & Rebecca) | Liquor Store owners in Texas
I purchased a CoolBot from you about 6 mos ago. [snipped] Our cooler is approximately 10 x 10 and built similar to what you proposed. I calculated a R factor well over 20. We use a 12000 btu unit from Home Depot and it works like a charm with the CoolBot. We store our large sizes of beer and all of our backstock in it.
[snipped]Our local taxidermist wants to build one
We've been opening doing extremely good business since. Thought I'd attach some pictures and just update you on the story. Thanks again for all your help. My only regret is that I didn't make it bigger.
Nat | Brewery and Bar in Wisconsin
Good afternoon. We purchased a used 6 x 8 walk in box in fair condition with bad refrigeration for our start up flower shop. I ordered a Coolbot and obtained an Arctic King mwduk12crbcj9, 12000 btu window unit. The Coolbot controls the Arctic King perfectly. It is one of the few things we have not had to worry about. Been working flawlessly for nearly 2 months. Thank you!
Jim | Georgia
Insulated 8ft by 9ft room with 4 inches fiberglass and 2 inch foam panels. Used GE 12000 btu air conditioner. Cools down quickly and will maintain 40 degrees easily with factory setting of 0. Used in floral application. Well pleased.
Ken F.| Florist in Mississippi
My staff just said thank you many times in the past few days for having this cooler.
Marc H. | Minnesota
I used my coolbot for the first time during a weekend where I had TWO weddings!! I will be honest I was worried that I would have a huge cooler failure. However, my coolbot was flawless!! It took it down to 39 degrees in no time and kept it there even when I was opening the door all the time. My cooler is homemade and roughly 6x8 insulated with R-19 fiberglass insulation and with R-10 rigid foam. I use a 12,000btu GE air conditioner and we water sealed the whole inside. I could not be happier!!! I added shelves after these photos were taken. Thanks for an awesome product that is PERFECT for a florist!!
We finally completed our Coolbot install at the flower shop, and we are impressed. We began with a 10'x12' used cooler. For this size, Coolbot recommended a 24k btu AC. However, I decided to go with two 14k btu units instead. I ran two 120v circuits from the main panel, so, in addition to a really fast cool down inside, we have a redundancy in the system where I'd unit can fail, and we won't loose product.
This cooler will get down to 38° fast. Perfect for our product.
John | Florist in Florida
Thought you might like to see. The evaporator on one of our reach in coolers pooped out. The repair guy told us it would be about $1800 to replace it.
Got a GE 6000 BTU AC at the local Home Depot & a new CoolBot. Cut a hole in the side and slid in the unit. Braced it in the back and sealed it up. Total install time was just over an hour.
Working great and saved well over a thousand bucks.
Bill | Florist in North Carolina
Attached is a pic of the coolbot. It is running great. I got the cooler finished just in time for Mother’s day what a great help it was. I sold a 6X6 Floral cooler for enough money to build an 8X8 almost double the size. Got tried of repair bills on the floral cooler. I read everything on a coolbot I could find before buying it all the reviews are great except I found one on a HVAC site they said it would never work. They are wrong. Wonder why they knock it, no repair needed maybe.
Brian | Colorado
You guys rock! I received new sensor on Monday back I business yesterday just I time for wedding flowers. I turned my tiny pump house into a cooler until I can afford a proper space.
Your customer service is awesome! Thank you very much
So far its working great! I tried this cooler before using CoolBot and my fins would always freeze up. Its really an amazing thing that it can bring the temp down that cold and not freeze up. My cooler is in the basement, I have 4 inches of the pink all the way around. Its used to store roses at around 38 degrees.
We are the proud new owners of a flower shop in the mountains of central Idaho (McCall) and after considerable effort, have finally gotten our cool bot to do what we need it to. Now that our cooler is up and running things are much more streamlined around the shop. Our cooler is only a 6x6, so it is small, but with 4 inches of rigid vapor-barrier energy seal structural blown-in foam, the cooler only runs about every 30 minutes if we don't open the door. With our 18K btu unit, it can go from 60 degrees inside the cooler to 23(our lowest recorded) in about 20 minutes. We've got it dialed in at about 42 right now which is why it runs so infrequently. I've found that I have to keep the settings pretty high in order to keep the room the right temp. That cooler unit is overkill (needless to say). Thanks for saving us time and money, even if getting it dialed in has been challenging!
Scott and Fallon F.| McCall, ID
[Ron's Note: They did such a great job on the cooler, but this problem of temperatures getting TOO LOW when the a/c unit is more than double the size needed for the room is not uncommon and can cause cold-damage to product. Settings can be adjusted to make it work, but it's better to start with the right size a/c unit. We actually encourage florists to size up a BIT. (Like 10,000 BTU's would have been fine) but 18,000 was a bit of work. I'm glad they are happy, now, though and they should stay that way!]
We purchased a CoolBot in June of 2009. We raise vegetables and cut flowers. Previously, we had had a compressor unit to cool our walk-in cooler. The CoolBot works extremely well and efficiently. It cools down much quicker than our compressor unit did.
It uses much less electricity then our compressor unit used.
We are extremely pleased with the unit.
It was economical and easy to install.
Dianne S. | Coopersville, Michigan
CoolBot got "Twitter-recommended" by EuroFlorist Corporate to 57,000 flower shops on July 2, 2009!!!!! WOW!!!! (You have to search through for that date.)
https://twitter.com/EuroFlorist - you have to search through for CoolBot.
I built this walk-in cooler in my wife's flower shop. It's been in service for about a month. Running flawlessly.
Cooler is approximately 7X9 [feet]. LG 12,500 AC. Everything hooked up easily. Works fantastic. After everything was running, temp. on 5 deg C [41F], I took the cooler door off the hinges to plane it down a bit. The temp jumped up to 16 deg C [61F]. After the door was re-installed the temp was back down to 5 deg C within 5 min.
Thanks for a great product. The flowers are doing really well.
Al | Owner of Flower shop in Canada
Hello Katie and Coolbot Team!
We thought we'd show you our finish product! We followed the restaurant plan and modified the frame slightly to fit our 1900's solid oak exterior French doors. We are even using the condensation once it is full enough to use with our flowers :)
Thank you so much for all your help!
Amanda S.| Florist Ontario, Canada
Dear Ron ...The new Kenmore got the temp down to 40 degrees from 70 in just a short time... Thank you!
Rick | Flower shop owner in West Virginia
[Note from Ron: They had originally tried the CoolBot on a Whirlpool A/C unit with a metal temperature sensor and it did not work. We offered to take the unit back but they wanted to try again with an approved a/c unit. Also, note that the CoolBot will go lower than 40 degrees, it's thermostatically controlled and they set it at 40 degrees.]

Hi Ron, do you remember me?
Well, finally, I am really happy to thank you once again about the CoolBot, really a great device! To built and insulate the coldroom was not an easy task... nothing is easy in Nepal! The work it was completed about 40 days ago... a really long wait!
Anyway, the best part is that, it works simply perfect, definitely over my expectation. Of course, the merit it is just yours... your device, and, not last, the suggestions wrote on your website, have made this possible.
For your knowledge, the air conditioner (12.000 btu) it is branded BEKO, this model it is with "inverter system" (lower consumption), it work perfect. So, thanks again Ron... I hope to buy two more CoolBot as soon as possible (as soon as I'll get more space!).
All the best!
Sandro | Nepal
[Note from Ron: I asked for more details, and he sent this information]
Some more details about the "cave"... has been insulated with polystyrene boards (nothing better here!) all over the surfaces, thickness 10 cm. Then covered with a thick plywood and finally covered with formica. It is a concrete block with a flat roof and there is no shade over it. When we started to use it, was mid of April, temperature was not really hot (average 25 C [77F]) but, it was also the time of 12 hours (6 + 6) daily power cut.
Anyway, also in that kind of situation, there was not the real need of use a generator. It was sufficient set the temperature a bit lower... in 6 hours without electricity, the inside temperature loss was 5 C... not bad, I think. Now, situation it is back to normal with almost 24 hours of power supply... and I am really impressed about temperature stability, just set it and you got it!
Last note, the cave is used to aging of cheeses and salami.
Funeral Home and Mortuary Coolers
We purchased a CoolBot from you last spring. We could not be happier with the results. We took what had been a single car garage with a door on both ends and made our cooler area. We created an 8' X12' precooler room for putting ID tags on remains and also to house the AC unit and keep it above freezing in the winter. We are 6500 feet elevation and we get four feet of snow per year so it does get cold in Arizona. The precooler room is insulated nearly as well as the cooler so I don't think the temp will get below 32 but if it does we will ad an electric heater.
The side walls of the garage were slump block so we erected walls of 2X6 on 24" centers. Our local Home Depot carries 2" sheathed styrofoam so we put two layers in the walls and ceiling. We then foams around the edges with aerosol foam. We free floated the floor as you recommended and covered with tongue and groove plywood. We used drywall on the walls and ceiling and put vinyl flooring on the plywood floor. We used a standard 3-0 insulated door from Home Depot and glued 2" of foam on each side. The finished cooler is 11' X 14'. A commercial cooler one third that size would have cost more than twice as much as we invested in this project.
We used the largest LG AC unit and it only takes 40 minutes for it to cool from 70 degrees to 38 degrees. We could not be more pleased.
Michael |Mortuary in Arizona
I have been using the cool bot with a homemade 8x8 cooler that I built since May or June of this year. The cool bot and the 12000 btu ac have been working great, keeping the cooler at 37 to 38 degrees F.
David | Funeral Home in Texas
Our business is growing so much that we needed to have place to store pets until it was time to start the cremation process for them.
Our 6x8.5x6.5 walk in cooler has a LG 15,000Btu unit on it. The CoolBot keeps the room at 38 degrees, and that is with the LG in energy saver mode. The first time we turned it on, it went from 82 degrees to 40 degrees in 15mins. And we were not even finished with the second layer yet. I was impressed….we got it in just in time as the 95 plus temps hit for the next week. The pic shows the cooler without the final layer of foam board. Which is now in. We have 4 inch insulation on walls, ceilings, and 2 over a concrete slab.
Max V. | Pet Crematory in Oregon
Our HVAC guy wanted to charge us $8,000 for a wine cellar cooling system. With your help, we purchased a ductless mini split and installed the Coolbot. We have a fabulous 1500 sqft wine cellar for less than half the price of traditional wine cellar cooling systems.
Excellent product! I've kept my wine cellar at 55 degrees for two years without a hitch. The AC unit is at the end of the bottle with the red cap. Thanks!

Private and Homesteader Coolers
We are operating the unit at 36-38 degrees with no adjustments to your default sensitivity and response settings. It cycles to 38 and starts to heat the sensor.....dropping down to about 34 as the cycle completes. Electric use was about $25 for one rather warm month, and now is non-measurable in the cool of winter. The air conditioner compressor cycles very little.
Kudos for a solid, dependable unit.... I need to "set and forget" the problem of keeping ALL my food and products cool.....I've been at the "Back to the Land / Homesteading", game since 1971. You can occasionally find our name in some of theiconic publications of the era. This unit is in the top 10 "Best of the Best" that I have experienced in 44 years.

Well I purchased a coolbot after being frustrated with having to call HVAC guys never getting a hold of them and very expensive for repairs so I've got it in my walk in refrigeration box that I use for crab storage and bought a lg 10000 BTU air conditioner and a coolbot from you guys took me a day to set it up and it's been running great ever since. It couldn't have been any easier to set up after the AC was installed.

Here is the picture of the CoolBot in action thank you for helping us get it on the right track!

This is the system I have, it works great! I wouldn't ever get another compressor system-this one works amazing!
Attached are pictures of the Cool Bot in our vintage deli case. We have rebuilt the case, with new glass, insulation and of course the Cool Bot. We started out with an older 6500 BTU LG unit, have upgraded to a new HAIER 8000 BTU unit. It will bring the case down to about 38 degrees in twenty minutes from room temp.
The case was given to us in April, we heard about the Cool Bot, purchased it and went about restoring the cabinet. It was a “simple” project that ended up with a major restoration. The cabinet originally had static cooling, was “insulated” with brown fiberboard, and had regular pane glass. It was taken down to the boards on the bottom (used originally as shipping pallets). We then put in four inches of rigid insulation on the bottom, added one inch on sides and top.
The Cool Bot works so well on the deli case, we are working on plans for building a walk in for our restaurant/tap room. By the way, at the request of our local health inspector, we moved the Cool Bot from the inside of the cabinet to the outside for easier monitoring.
Thank you for an excellent product.

The coolbot has done the job well this past year. You were right about the fin sensor. Thanks for the new one. It did the trick and we've been humming along with the pickles.
We are taking another space to expand and will be using another Coolbot.
Thanks for the product and the service.

We have been needing a walk-in cooler for our church commercial kitchen for roll-in carts when we do large events. Found the Coolbot in my research and designed a plan.
Purchased the Coolbot and a GE 14,250 BTU 110v digital window AC unit.
We built a 2x4 frame wrapped in OSB outside. Inside we used the scrap pieces to line the framing with an extra 2" of the RMAX sheathing. Then we overlaid 4" of RMAX on top of the 2x4 walls and ceiling giving us 6" on the walls and 4" on the ceiling. We overlapped all the seams, used spray foam insulation for any gaps and then lined all the walls with FRP to protect the insulation. Left the ceiling as it was. We have a concrete painted floor that is perfect for rolling carts on.
When we turned on the AC unit with the Coolbot in control it dropped our walk-in from 70 to 37 degrees in 20 minutes. When we open the door for up to 5 minutes it returns to temp in four minutes.
We could not be happier with the whole project and it worked flawlessly for a large wedding last weekend. We built the whole project for under $2,000. Everyone is pretty amazed!

We even have 2 doors. I did use flaps on both doors, that probably helps. It's our primary cooler again, and we are in and out a lot. I oversized from your recommendations because of that. I also insulated the floor. Its amazing. The beer distributors are totally impressed. I am always around 33/34. It's great!

I recently purchased a CoolBot and couldn't be happier. This CoolBot is in my milk cooler at our grocery store. I have a Frigidaire AC and have had temps down to 28. It does vent to an inside room and then goes outside through the dock. The average temp is 34. Thank you so much for such a great product. I will soon be purchasing my 3rd CoolBot.
Jack C. | Grocery Store Owner
I have been using your product at my restaurant for a few months now. Fantastic is all I can say about it. Any plans for a unit to make a freezer model? I would buy one.
[We get asked about doing a freezer pretty often, but... it's not possible with an a/c unit. They are great down to 36-38F, but even below 36F our system isn't so great. While we do have some customers cooling at 33-34F, they have to massively oversize the air conditioners compared to our specifications and the recovery (every time people open the door) is REALLY slow.]
..the room we converted into the cooler was 11x11. so after spending quite some time trying to find the right insulation (in Hawaii) we still ended up getting the white Styrofoam from home depot (R-3.6). to get that blue stuff was just impossible.
..this CoolBot is a utmost genius idea. when i started to look into these commercial coolers it got kind of frustrating to see the horrendous prices and everything that goes with it. for a short moment i had that thought if an AC could be converted. strangely enough some time after i came across you guys website and was kind of fascinated about the idea and that it works that way. If i get the opportunity i will spread the word.

Per our conversation yesterday, I wanted to share with you our very successful installation of a walk in cooler for our restaurant. We have a kitchen that has several reach in units for when we are in service, and we store the prepped food in those units. However, we needed a significant amount of additional storage, and built this walk in in our basement. It is accessed about 10-15 times a day by our staff to retrieve items.
We did not skimp on the installation, using 4" of rigid styrofoam insulation, 4" of Roxul (check that stuff out, it is wicked cool), with the addition of sheetrock, plywood, a 2x4 frame and FRP to finish the unit.
The materials for the walk in were about $3,000, the AC was $400 and the CoolBot was $299.
If you built it yourself you could save about $2,500 instead of purchasing one of a similar size.

[Ron's Note: Eric provided extremely detailed information as to how they built a cooler in their restaurant which we've posted as a PDF in the cooler construction of the website]
I spoke with you a couple of times last year after I bought my coolbot. I love this thing, and I tell all of my micro bakery friends about them. It really is a marvelous invention....[snipped]
PS. My energy bill dropped by 350 to 400 KWH per month with the coolbot installation.
Noah E. | O.H. Breadworks, New Hampshire
I bought your product in September 2015. We just got the walk in cooler done and up and running. Well I have to say it works way better than our old commercial compressor ever did. It will stay 33 degrees if we need it to without a problem.
Rodney B. | Illinois
Hi Ron and Katie,
Just to let you know our CoolBot has been working without a hitch ever since Ron's call a few weeks back. In addition to all your great advice (including disengagement of secondary sensor), I also figured out from your website that our primary frost sensor was in the wrong place. The person who helped us with installation had already done another CoolBot (some years ago, with a different A/C unit) so I didn't think to double-check placement straight away.
BTW rather than waiting to see where frost would start to form again, I took note of where ice was last to leave (as in a spring snow-melt) with just the A/C unit fan turned on high . Worked slick -- I was able to pinpoint optimum frost-sensor placement without waiting for problem to recur (yet again!). FYI a pool thermometer floating in 5-gallon bucket of water is also working great for monitoring product temperature.
Thanks again for everything,
Rebecca | California
Updating you on how things turned out after I spoke with a support person yesterday about my coolbot not working properly. Temperature had been at set level of 41 degrees for a week or so. Then 48 was the best it could do. Called you folks, you called back in a very short time. Told me that it probably was a secondary sensor in my GE air conditioner that was still in it's copper cup. Support person explained very well how to find it and pull it out and away from metal and air flow. I went to repair AC unit, found just what she said I would, pulled it out and away. Went back two hours later to check, room temperature was at 41 degrees. THANK YOU. ANOTHER SATISFIED CUSTOMER.

Outside view of cooler using CoolBot. Not quite finished but got power connected and CoolBot hooked up so did test run. Took exactly 1 hour to go from 80 down to 35 degrees!
These things are amazing…I can easily get the temperature to 32 degrees in our room….we are very pleased with the CoolBot system.
Dennis M. | Ohio
Store It Cold Disclaimer: We're obviously psyched these folks can get to 32 degrees and we do have other people running that cold by super-sizing their air conditioners relative to their room size and never opening the door, but 95% of our customers shouldn't count on ever being able to see temperatures that cold. Check out this http://www.storeitcold.com/disadvantages.html page for CoolBot
Here are pics of the 8'X8'X8' cooler we built. The CoolBot works great! It dropped the temp from 87 degrees to 38 degrees and held it there.
Frank | Hazelhurst, MS
Wow: I was very skeptical about the product. , but I followed your instructions and recommendations and build a 10' X 8' cooler using the prints from the University of Kentucky. I was very pleased and amazed that the first afternoon we plugged it in that we had 0 problems and let it run overnight and the next morning it was 33 degrees in the cooler. I live in south Louisiana and it was an 80 plus degree night and the cooler was at 33 degrees. Thanks for a great product. Thanks
Just a follow up. I bought a CoolBot earlier this year for a cooler I built down in North Alabama. It's brick, 6' x 16' x 9' with a 14,500 BTU AC unit. Just wanted to let ya'll know how it's doing. Holding 37 F and 55% RH very steady even in upper the 90s and the AC unit only runs maybe ten minutes every hour or so if I keep the doors closed (double steel doors). It's so cold it actually hurts after a few minutes, being used to 90s summer temps outside. I do have several large shade trees protecting it from the sun which helps but it has a concrete floor with no insulation so I'm very impressed with how well it's been working. It did start recently icing up a bit but I forgot I need to clean the fins once in awhile so I did and it works fine now! :-) I'm very happy with it and will continue using the CoolBot. Outstanding invention!
Thanks so much. The unit worked out great this year. Hope to be needing another one in the near future!
Jeff E. | Ohio
We've been running a CoolBot in our 6' x 8' walk-in for three years now and have loved it. It has given us zero issues until now. We are now getting a strip of ice a couple inches wide across the bottom of the fins on the inside and we have to keep unplugging it to let it thaw out.
Do we need to do any maintenance on the air conditioner?
Steve V. | Farmer, West VA.
[Ron's Note: The answer to that question is definitely yes! The problem here was just that it needed to be cleaned. (preferably once a month rather than once every 3 years!) Dust/Dirt/Lint blocks up the fins as well as the channel that takes the condensate to the back of the air conditioner. It can also get on the compressor causing it to overheat. Please pull your a/c units out of the cabinet 1-2 times per year and hose them off. Use a long stiff bristled brush and a plain cup of water to swipe down the fins once a month.
I have built a 12 12'X12'X6 1/2' cooler with 3" closed cell spray insulation, 1" hardboard insulation with 1/2" OSB on inside and outside walls. There is 4" of blueboard under a 4" cement floor. This is inside a barn.
Just wanted you to know that the cool bot is working great. The cooler is running at 37 to 39F all the time. I am super happy with the unit. Thank you for inventing it.
Farmer Dave | North Berwick, Maine
First of all I am very pleased with cool-bot I got just in time for the warm spell 2 weeks ago and it did great!( I built a 8X8X8 walk in cooler with floor and ceiling 3 1/2 inches styrofoam)If you have any one in my area thinking about one you can use me as a reference. I do have a question and it may seem silly but now that the temp is low and below freezing at night should I remove the cool-bot and move to a warmer location? I know it is made for refrigeration but I am not sure if freezing is a factor?
Dante Picarelli | Pennsylvania
Just want you to know,that CoolBot is real good.. i finished my 6 by 6 cooler and even with this heat the last few days,it has been at 40, have had it as low as 32.
Mark S. | Plainfield, CT
Hello again Katie,
I wanted to follow up on this (many months later) since I just received my Coolbot (ordered through Amazon Prime) and am currently testing it out.
WOW, I'm very pleased!
A few months ago, I order one of the recommended GE window units. The lowest temperature the unit will go down to is 64 degress - now that is fine when the nighttime temps are in the low 80s to high 70s (like they are from about June-September here in North Texas), but for the past couple of weeks the low temps are in the lower 60s to upper 50s, and because of that, the window a/c cools the room so quickly that the compressor does not run often enough to clear out the humidity out of the room (almost always very humid here), so even with a room air temp of 64, my room felt clammy and uncomfortable to me.
Well, as I hoped, it looks like the Coolbot will take care of this quite nicely . . . now the a/c compressor runs much more, since the unit is tricked into thinking the room temperature is far warmer than it really is, and the air feels much more comfortable. I am not so concerned with reaching the mid-low 50s that I mentioned in my precious emails to you, as I realize that is probably unrealistic unless I were to take major steps to further insulate my room, but I'm finding that even getting the air temp down to just 57-60 with the Coolbot will make the air in the room feel very refreshing.
I was able to install and adjust the Coolbot without problem (excellent instructions) and I am really happy to have found such a wonderful device! I'm definitely looking forward to experimenting with it in the coming days to see how it performs and find what I consider the temperature "sweet spot" for me.
Thank you for your previous help, and I will contact you if I have any future questions and comments.
[Note from Ron: Every once in a while we get emails inquiring about using a CoolBot to trick an a/c in a bedroom to cool down the room lower than the unit. It can work, but as Ron mentioned, the amount of insulation will certainly impact how much colder we can get it. We have a great answer to this on our FAQ too, which can be found here: FAQ]
I've purchased 2 of your units and used them in a 12'x16' room that I use as a cool room for show cattle. I have 2 GE 24,000 btu units. Fired it up last night and went from 70 degrees to 40 in 15 min.
Brent | Show Cattle Cooler
We really love hearing from you the details of the cooler you made, the size a/c you are using and what temperature you've set the CoolBot to run at as well as what the application is (farm, florist, restaurant, caterer, industrial, mortuary - we even have people storing vaccines with the CoolBot!)
