Information about the device
Device description
This device TTK 128 E uses the principle of condensation to
automatically dehumidify rooms.
The fan sucks damp room air through the air inlet (5), the air filter,
the evaporator and to the condenser located behind it. The air is
cooled at the cold evaporator until it is below the dew point. Water
vapour contained in the room air precipitates on the evaporator
fins as either condensation or frost. At the condenser the
dehumidified, cooled air is warmed by a few degrees and blown
out. The drier air thus conditioned mixes with the air in the room.
The humidity in the room where the device is positioned is
reduced as air constantly circulates through the device.
Depending on the air temperature and the relative humidity, the
condensed water either drops continuously or only during the
defrost phase through the integrated drain nozzle into the
condensation tank (7) below. It is fitted with a float to measure the
filling level.
The device has a control panel (1) for operating and controlling
the functions.
Once the maximum fill level of the condensation tank (7) is
reached, the condensation tank indicator light (see chapter
Operating elements) on the control panel (1) is illuminated. The
device switches off. The condensation tank indicator light only
goes out again once the emptied condensation tank (7) is
reinserted. The condensed water can be diverted by attaching a
hose at the condensation connection (6). The device can reduce
the relative humidity of a room by up to approx. 30 %. Because of
the heat radiation generated during operation, the room
temperature may rise slightly.
