Information about the device

Device description

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 filling level of the condensation tank is reached or in case the condensation tank is not installed correctly, 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. Optionally, the condensed water can be drained by attaching a hose 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.
