Operating Principle

Adsorption Technology

ADS series units operate on an adsorption principle using two separate air streams. Process air passes through the silica gel rotor; the silica gel absorbs water vapour from the air, drying it. As the rotor slowly turns, regeneration air is directed in the opposite direction: heated to +100°C by electric heaters, this airstream strips the absorbed moisture from the rotor, restoring its initial adsorption capacity. The moisture-laden regeneration air is then discharged to the outside.

01
Process Air Inlet

Humid air passes through a G2 filter and is directed to the silica gel rotor; the fan drives the airstream using negative pressure.

02
Adsorption

The silica gel rotor adsorbs water vapour from the process air; the dried airstream is delivered to the process or conditioned space.

03
Regeneration

PTC electric heaters raise regeneration air temperature to ~100°C; this hot airstream passes through the rotor in the opposite direction, stripping and expelling moisture.

04
Continuous Cycle

The rotor slowly rotates between adsorption and regeneration zones, providing uninterrupted dehumidification.
