The CoolBot turns most brands of off-the-shelf, window-type air conditioning units (purchased separately) into a turbo-charged cooling machine. Transform a (highly-insulated) room into a walk-in cooler, keeping products fresh and temperature controlled cool to 35° even in the heat of summer. Truly DIY. No tools or electrical knowledge required (See our youtube installation video). Installs in 2-3 minutes on (many) major brands of window air conditioning units purchased separately, including LG, Danby, Haier, Samsung and GE. (Check your brand before purchasing on our website -- You *MUST* use StoreItCold sizing charts and recommended air conditioners brands or the CoolBot won't work.) CoolBots save customers up to 80% on upfront and installation costs compared to standard walk-in cooler compressors, and lower monthly electricity bills as well. CoolBots are perfect for hunters, farmers, and florists. CoolBots are recommended by many University extension programs. Do a quick Google Search to read articles about how many people use this system. * Read below to MAKE SURE it will work for you before purchasing, or call and ask * CoolBots have less than a 1% return rate, but they are *NOT* appropriate for all applications! *Rooms require 4" of rigid foam insulation, floors, walls and ceiling. Less insulation and the unit only cools into the 40's. See construction tips on our website. *Requires use of StoreItCold sizing and brand recommendations. Undersized/off brand air conditioners WILL NOT WORK! *CoolBot rooms get down to 43 degrees quickly, then slow down (because of minimal fins/fans in standard air conditioners). Uses involving more than 6 openings/hour (many restaurants) are TOO MUCH for CoolBots to keep up. Temps will be in the low 40's and not safe for food. Don't buy. Caterers/small cafe's love CoolBot. Large busy restaurants would NOT except as a secondary cooler.
