3. Function overview
The desiccant rotor is the adsorption dehumidifying component in the unit. The rotor structure is com-
prised of a large number of small air channels.
The desiccant rotor is made of a composite material that is highly effective in attracting and retaining
water vapour. The rotor is divided in two zones.
The airflow to be dehumidified, process air, passes through the largest zone of the rotor and then
leaves the rotor as dry air. Since the rotor rotates slowly, the incoming air always meets a dry zone on
the rotor, thus creating a continuous dehumidification process.
The airflow used to dry the rotor, reactivation air, is heated. The reactivation air passes through the
rotor in the opposite direction to the process air and leaves the rotor as wet air (warm, moist air).
This principle enables the dehumidifier to work effectively, even at freezing temperatures.
