Information about the device
Description of the device
This device uses the principle of condensation to automatically
dehumidify rooms. To do so, the device can be used in continuous
operation.
The fan sucks damp room air through the air inlet (5), the air
filter (7), 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. The dehumidified,
cooled air is warmed again and blown out from the air outlet (6).
The drier air which is prepared in this way 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 into the condensation tray. The condensation is fed
through a pressure-resistant pipe connection and out of the device
at a preinstalled condensation drain hose (4).
The condensed water can be diverted by retrofitting a
condensation pump.
Device depiction and operating elements
For easy operation, the device is fitted with a control panel (2) and
for easy transport, it is fitted with a bar handle (1) and wheels (3).
The device can reduce the relative humidity of a room by up to
approx. 35 %. Because of the heat radiation which is tied up in
operation, the room temperature can rise by approx. 1 – 3 °C.

Power consumption
The device's power consumption depends on the current room
temperature and relative humidity.
Multiply the operating hours (see operating hours counter (12)) by
a consumption value of one kilowatt per hour to determine the
approximate power consumption.
To determine the precise power consumption, a separate energy
cost gauge can be set between the construction dryer and the
power source. Contact Trotec customer service if you want this
alternative version.
