Applications
The dehumidifier AD is a desiccant dehumidifier, a rotary type using a humidity adsorbing rotor to
dehumidify air at atmospheric pressure. It can be used to dehumidify air at relative humidity up to
100% and temperature from -30°C to +40°C.
There are so many applications and the following are some examples:
Humidity control in production processes
Drying of temperature-sensitive products
Maintaining the proper level of humidity in the storage warehouses
Corrosion protection of plants and in general of ferrous materials
Humidity control in museums and libraries
Drying properties after flooding and construction
Improvement of the environment everywhere occurs excessive moisture
Principle of operation
This dehumidifier works in a continuous process with
two air streams, process air and reactivation air. As
shown in the figure, a honeycomb rotor dehumidifier
consists of a honeycomb adsorbent rotor, which is
rotated, in a casing at a low speed of around 8 rph by
a geared motor in the outer circumferential drive
method. The casing is divided into two sectors of
process zone and re generation zone.
Process air is led in the process zone to contact the
rotating honeycomb rotor. While it passes through the
honeycomb channels, water vapor is adsorbed and it
becomes dry air to be supplied. Sometimes later, the honeycomb rotor having got wet due to moisture
adsorption enters the regeneration zone by rotation. The rotor is reactivation by hot air passing
through honeycomb channel and turns again to the process zone. Dry air can always be produced in
stable conditions by this continuous cycle. Process air is dried in the rotor between -30°C and +40°C,
the re generation air is beaten by an internal coil up to about 100°C.
