The AD air dehumidifier is intended exclusively for air dehumidification in closed
rooms. The air dehumidifier can prevent the formation of condensation water,
remove excessive humidity and keep humidity at a defined constant level. The
operating time of the air dehumidifier until drying of the room and the humidity
to be reached depend largely on the ambient conditions in the room in which the
device is installed.
The AD air dehumidifier works on the principle of condensation with heat
recovery. The fan draws the moist air in through a cooling coil (evaporator). In the
cooling coil the air is cooled so far below the dew point that the water steam of
the air condenses and flows into a water collecting tank. The cooled and dried air
is re-heated at the condenser. Due to the heat pump effect the output air is a few
degrees warmer than the room air drawn in. The resulting energy gain can reach
3 times the electrical energy consumption.
Permanent circulation of the room air through the device continuously reduces
the absolute humidity of the air. The excessive humidity is removed gently and
excessively.
