How it works

The CoolBot drops the temperature of a well-insulated room to as low as 34ºF without freezing up the air conditioner fins. It's truly DIY -- you can set it up in 2 to 3 minutes, with no tools or electrical knowledge required.

What you need

All you need to create a DIY walk-in cooler is a well-insulated room, a CoolBot, and a standard window or mini-split air conditioner with digital controls. The CoolBot works with several major brands of air conditioners.

Application information

CoolBots are best suited for fully enclosed rooms with at least R25 insulation (~4" of rigid foam) where the door is opened fewer than 6 times per hour. If the insulation is less than 4" or the door is opened more than 6 times per hour, the temperature will be in the low 40s.
