Product Overview
A CoolBot allows a standard air conditioner to cool a room or space down to 35 degrees F. Installs with no tools or electrical knowledge required.
Standard A/C units available from any hardware or appliance store have lots of power but they are electronically limited so that they cannot go below 60 degrees F. This is because they would freeze up. Commercial refrigeration for walk in coolers combat freeze with increased surface area on the fins as well as fans. Instead the Cool bot technology uses multiple sensors, a heating element and programmed micro-controller to control your air conditioner in such a way that the unit can go below 60F and not freeze up. The Coolbot cannot give you 100% of the btus listed on your air conditioner nor is suitable for large brewery or winery walk ins. It is perfect for wine cellars, beer storage, fermentation, etc.
Easy to install within 30 minutes with no tools or electrical knowleged required. While we can't tell you exactly what size space you can cool because of ambient temperatures and insulation factors, we recommend you google Coolbot. They have sold over 50,000 of these so there are lots of reviews and actual installs out there. We offer free shipping on this unit, ship fast from both coasts, and have great customer service.
This type of system is also very efficient. Most commercial systems are power hogs with large fans that are always running. Residential A/C units are made for efficiency. The Coolbot will also shut down the compressor for short time when the unit is running at its highest level of inneficiency, as it nears freeze up.
- Dims of the CoolBot are 6.5x3.5x1.5 in.

James I set the cool bot for 40 degrees using a small LG air ...
simple to hook up works as advertised. The room I constructed for cooling venison is 3w by 8 L by 7H . I set the cool bot for 40 degrees using a small LG air conditioner. It is too warm in ct. in September to hang bow harvested deer outside, heat, and yellow jackets, the cool bot set at 40 degrees bottomed out at 43 which is great, you have to remember the sensor hangs at the half way height of the room so it is even cooler at the floor. Also if I caulk better with some low expansion foam every crack and cranny and maybe hang a curtain in the door way I can pick up another couple degrees of cooling. I used R32 fiberglass with insulating panels for the walls.I am very happy with the product it is worth the price of admission!

Hank L. excellent unit!
in the past 6 years, I have built 18 walk-ins, reach-ins, and one large enough to accommodate a forklift..have always used an LG AC( if that helps)..have never had a single complaint, nothing but flawless, maintenance-free operation..just spoke with the owner of the first project from 2009 and was told he loves it..has never touched the controls since I set them the day we started it up..his praise was mostly responsible for convincing the other owners to have theirs built
