Quest PowerDry 4800D Pro

The Quest PowerDry 4800D Pro has been developed in response to the industry’s need for a rugged, efficient, user-friendly desiccant dehumidifier. The PowerDry 4800D Pro is equipped with circuit breakers, eliminating down time caused by blown fuses. Weighing just 1600 lbs. and mounted on a narrow 48″ skid, this unit is much easier to transport than many units of similar capacity. Requiring only 106 amps, this 4800 CFM desiccant consumes less energy than competing designs.


Standard conditions are determined by the American Home Appliance Manufacturers (AHAM) and are used because capacity will vary with conditions. AHAM standard rating conditions are 80ºF and 60%RH. At these conditions, the capacity of the Quest PowerDry 4800D Pro is 3032 pints per day.
