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.
For the WiFi-enabled model, see the CoolBot Pro.
