2.1 Product description
The desiccant dehumidifiers in the IceDry series have been developed to effectively dehumidify the air in
cold stores in order to minimise frost and ice build-up
The dehumidifier is equipped with an encapsulated rotor unit. The rotor casing is constructed of durable
thermoset plastic and contains isolated sections that provide a precise balance for the dehumidification,
reactivation and heat recovery airflows.
The electrical control system complies with the EN60204 (IEC60204) standards. For operating
temperature, see section
The dehumidifier is manufactured in accordance with uniform European standards and established
requirements for CE-marking.

Figure 2.1 Principle of operation
1. Process air
2. Dry air
3. Reactivation air
4. Wet air
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 air flow to be dehumidified,
process air,
passes through
the rotor's largest zone 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 air flow 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.
