The rotor is the adsorption dehumidifying component in the unit. The rotor structure is comprised 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 that is 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.
The rotor is monitored by a rotation sensor to enable an alarm if the rotor stops unintentionally.
