PRINCIPLE OF OPERATION
The Aprilaire 1850 Series Dehumidifiers are designed to
dehumidify the air coming into the unit by passing the incoming
air over an evaporator coil to drop the air temperature below the
dew point of the air. Moisture is removed from the air and drained
out of the unit to a common floor or waste drain. The air is then
reheated in the condenser coil and exits the unit.
Dehumidification occurs until the set point is reached, then shuts
o until periodic sampling determines a need for operation.
APPLICATION
The 1850 series is perfect for a wide range of applications
including whole-home dehumidification and control of moisture
in basements and crawl spaces.
CIRCULATION
The 1850 series can also be programmed to circulate air, which
evens out relative humidity levels and temperature in the treated
space, eliminating variations in the environment.
