Product- and functional description

Introduction This section will give you a description of the CDF 35/45 and its functionality.
Functional CDF 35/45 are working in accordance with the condensation principle. The humid air is
description drawn into the unit by a fan. When passing through the evaporator the air is cooled
down to below dew point and water vapour is condensed into water, which is drained
away. The now dry air is then passed over the condenser coil where the air is heated.
As a result of the released evaporator heat and the working energy of the compressor
being turned into heat energy, more heat is returned to the air than was previously
extracted. This extra heat corresponds to an approximate increase in temperature of
5 °C. The repeated circulation of air through the unit reduces the relative humidity,
giving very rapid but gentle drying.
Air flow This illustrates the air flow:
Built in hygrostat The dehumidifier is controlled
by a built-in hygrostat that is
set to approx. % RH. When
the hygrostat registers a
relative humidity of more than
%RH, the compressor and the
fan automatically switch on and
the dehumidifier starts to
dehumidify.
Note!
humidity is below %RH, the
unit will not start when the
power is connected
