Product Lines

Koldwave air conditioners are portable, and do not need a window to function. Traditional air conditioners expel the hot air to the outdoors through a window, but this is not necessary with a Koldwave unit. The water-cooled Kompac units use water (rather than outside air) from a faucet or closed water loop to cool the air. The Airmaster air-cooled units provide cooling through a ducting process. The manufacturer notes that its Airmaster air conditioners can also be used for cooling at outdoor events or spot cooling in areas such as server rooms. Koldwave heat pumps are part of the water-cooled line. The water-cooled air conditioners can vary from a cooling capacity of 6,300 to 34,700 Btu/hour and a heating capacity of 7,000 to 38,500 Btu/hour. The air-cooled units range from 13,200 to 61,200 Btu/hour.


Koldwave warranties its air conditioners for two years, for both parts and workmanship. The compressor is covered for three years under the Koldwave warranty.
