Dehumidifier
Model 1870 Series | Specification Sheet
PRINCIPLE OF OPERATION
The Aprilaire Model 1870 Dehumidifier is 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 Aprilaire Model 1870 is perfect for a wide range of applications
including whole-home dehumidification and control of moisture in
basements and crawl spaces.
CIRCULATION
The Model 1870 can also be programmed to circulate the air within a
crawl space. Circulating the air evens out relative humidity levels and
temperature in the space, eliminating variations in the environment.
