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. Visit our website to learn more.
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.
