Adiabatic Air Conditioning (AAC) produces cool air by evaporating water within a unique heat transfer medium. The temperature of the supply air is reduced in direct proportion to the amount of water evaporated into the air stream. AAC systems operate with 90% less energy than traditional refrigerant AAC equipment, saving fuel and fuel costs.

Unlike refrigerant equipment, AAC systems do not recirculate stale inside air. Using fresh-filtered outside air improves interior air quality, minimizes infiltration, saves fuel and increases passenger comfort. This technology is ideal for buses, where excessive cooling loads, constant stop and go operation and opening doors impose severe challenges to refrigerant cooling technology.

AAC technology uses no refrigerants, no toxic chemicals, no ozone destroying compounds and no greenhouse gases. As a result it is safe for passengers, drivers, mechanics and the environment.

VehiCool's quality AAC systems are available in a variety of designs for roof or rear mounting, in single or two-stage configurations, with ventilation, cooling or heating capbilities. VehiCool units can also be custom designed for specific applications. Components are industrial/transit quality for high reliability and long service. The company also offers extended warranties and comprehensive service that guarantee your cost savings.
