Desiccant Dryers

<< Back to Pneumatech page

These innovative desiccant dryers give customers efficient protection against the presence of any humidity in the air, which often is the source of:

  • Corrosion, pollution and leakage of the airnet.
  • Decreased efficiency of equipment/tools.
  • Freezing of water in the airnet.

A desiccant dryer uses desiccant material to adsorb and remove the humidity from compressed air. With this method a pressure dew point as low as -73°C/-100°F can be reached. A desiccant dryer should be used when the ambient temperature goes below freezing point, to avoid ice forming in pipes and applications.
