CRAWL SPACE DEHUMIDIFICATION
The Aprilaire
®
dehumidifier controls the humidity level in your crawl space. A powerful blower inside the dehumidifier draws air into the
cabinet, filters the air and removes moisture, then discharges the dry air into the crawl space. Inside the cabinet, a sealed refrigeration system
removes moisture by moving the air through a series of tubes and fins that are kept colder than the dew point of the incoming air. The dew
point is the temperature at which moisture in the air will condense, much like what occurs on the outside of a cold glass on a hot summer
day. The condensed moisture drips into the dehumidifier drain pan to a drain tube routed to the nearest floor drain or condensate pump. After
the moisture is removed, the air moves through a second coil where it is reheated before being sent back into the space. The air leaving the
dehumidifier will be warmer and drier than the air entering the dehumidifier.
