Product- and functional description
Introduction
This section will give you a description of the CDF 35/45 and its functionality.
Functional
description
CDF 35/45 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 be-
ing turned into heat energy, more heat is returned to the air than was previously ex-
tracted. 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. 60 % RH. When
the hygrostat registers a rela-
tive humidity of more than
60 %RH, the compressor and
the fan automatically switch on
and the dehumidifier starts to
dehumidify.
Note!
If the air hu-
midity is below 60 %RH, the
unit will not start when the
power is connected
