Information about the device
Description of the device
The device uses the principle of condensation to automatically
dehumidify rooms.
The fan sucks damp room air through the air inlet, 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 condensation or rime. The dehumidified,
cooled air is slightly warmed at the condenser and blown out
again. 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 below. It is fitted with a float to measure the
filling level.
The device has a control panel for operating and controlling the
functions.
Once the maximum fill level of the condensation tank is
reached, the condensation tank indicator light (see chapter
Operation) on the control panel is illuminated. The device
switches off. The condensation tank indicator light only goes out
again once the emptied condensation tank is reinserted. On the
TTK67E and TTK73E, the indicator lights also light up if the
condensate tanks are not inserted correctly.
Optionally, the condensed water can be drained by attaching a
hose (Ø = 14mm) at the condensation connection.
The device can reduce the relative humidity of a room to approx.
30 %.
In addition, the device may also be used as a kind of clothes
dryer to dry wet laundry in living or working spaces.
Because of the heat radiation generated during operation, the
room temperature may rise slightly.
The devices TTK67E, TTK68E and TTK73E differ in their
appearance and design. They are similar in operation.
