The dehumidifier removes water from an airflow through, and
the removed water is carried away from the dehumidifier with
the regeneration air (henceforward called reg.-air).
Water adsorption and -extraction takes place in an rotor made
of water resistant silica gel.
The airflows in the dehumidifier divides the rotor in two
parts : drying part and reg.-part.
Two separate air flows passes through the rotor:
- the main air (moist air inlet) goes through the drying
part, and leaves the dehumidifier as dry air
- the reg.-air coming from the reg.-air fan, passing the
electric heater and leaves the heater with a temperature
of 135C. This warm reg.-air now goes through the reg.-
part and the energy is used for evaporation of the adsorp-
ed water. This water vapour now leaves the dehumidifier
within the reg.-air. (see principle fig.1, page 2 ).
The two air flows are fixed and the rotor turns - this gives
an automatic process of simultaneous water adsorption and wa-
ter extraction.
The inlet conditions of the air to be dried, determines how
much water the dehumidifier will remove.
On page 8 the capacity diagram shows how much water will be
removed per kg air going through.
(shown in the diagram)
- inlet air conditions 20C, 60 %RH, gives water content 8,7
g/kg
- the diagram shows then dry air condition of X= 3,2 g/kg
- removed per kg air is then: 8,7 - 3,2 = 5,5 g/kg
Dry air flow is nominal 300 m3/h = (x 1,2) = 360 kg/h
Capacity, removed water per hour = 360 x 5,5 = 1980 g/h
= 47 kg/24h
- at 400V.
The temperature of the dry air is higher than for the inlet
air. This is caused by the evaporation heat release and heat
gain from the rotor. The temperature is shown to be 42C.

Dehumidifiers in the CR range is used for dehumidification
of ambient air at normal atmospheric pressure. This can be
an installation for moisture control in an unheated store
room, in a water work building, production room for hygro-
scopic materials... - with the dehumidifier in a separate
installation.
The dehumidifier also can be used as a part of a bigger air
treatment system. Here the dehumidifier often will be placed
in a by-pass to the main system.
In this case the pressure in the main system will influence
the dehumidifier - and your supplier must be contacted, as
this can influence the capacity of the dehumidifier.
Normally the dehumidifier will be placed in a wall bracket
or in a frame placed on the floor. Both parts can be sup-
plied as options.
The air to the dehumidifier should be free from solvents or
other explosive components, and should be free from pollu-
tion from solid particles and chemical substances ( ex.
acids, bases...).
- max. humidity ...................... 100 %RH
- max. temperature ................... 35C
- max./min. pressure ................. ambient +/- 300Pa
2. APPLICATIONS.
For air to the dehumidifier the following limit values
must be respected :
The CR range is for indoor, stationary installations.
Should not be placed in rooms with possibility for free wa-
ter on the cabinet.
