This section will give you a description of the CDF 35T/45T and its functionality.
CDF 35T/45T are working in accordance with the condensation principle. The humid air
is 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.
This illustrates the air flow:
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! If the air humidity is
below %RH, the unit will
not start when the power
is connected
