Sorptionsentfeuchter

Regeneration Air Outlet:

  • The regeneration air in couterflow dries out and therefore «regenerates» the sorption wheel

Process Air Inlet:

  • Up to 200’000 kg/h
  • Usually flows through 180° up to 270° sector (as shown) of the sorption wheel
Sorption Dehumidifier Heat Exchanger Unit

Regeneration Air Inlet:

  • Temperatures in the range 120-170°C
  • Usually flows through 90° (as shown) up to 180° sector of the sorption wheel

Process Air Outlet:

  • Can be dried down to below 2 g/kg humidity without condensation

Main Features

  • Unit to dehumidify process air without condensation
  • Making use of the (ad)sorption process defined as the accumulation of molecules on a surface 
  • Core part is the so called sorption wheel which accumulates (adsorbs) the water dissolved in the process air on its surface
  • Many additional components can be included in the sorption units (see optional equipment) according to the client specification and request

Materials And Characteristic Values

Seal of sorption wheel
Seal of sorption wheel
  • Sorption wheel (also known as desiccant wheel): silica gel
  • Rotation: maintenance-friendly chain drive with a constant speed of around 10 to 15 rotations per hour
  • Seals: radial and axial seals (as shown on the right) to separate the two counter flows from each other and from the surroundings
  • Housing: Stainless steel with mineral wool insulation

Optional equipment

  • Regeneration air heater (e.g. steam)
  • Pre-cooler (condensation dehumidifier) for higher drying capacity 
  • Air cooler after the sorption wheel (as the air gets heated up by the drying process)
  • Heat recovery systems
  • Sound attenuators
  • Filter stages for both process and/or regeneration air

Customized according to client specification and request
