Heatless desiccant dryer

Heatless desiccant dryer

Simple and reliable. -40 degrees Celcius pressure dew point.


Our adsorption dryers are designed for continuous separation of water vapor from the compressed air thus reducing the pressure dew point to -40 degrees Celcius. The series dryer consists of two columns, filled with desiccant beds, PLC controller, valves, manometers, support construction and suitable filter housings with the required filter element.

Adsorption takes place under pressure in the first column while the second column regenerates with a portion of already dried compressed air at ambient pressure. When the first column is saturated to a certain level column switch-over is carried out and the process of adsorption continues in the second column without any drop of pressure at the outlet of the dryer. Regeneration of saturated desiccant is possible because a small portion of already dry compressed air is decompressed and when expanded it becomes extremely dry.

DPC – Energy saving dew point control

Our dryers are equipped with dew point control thus reducing the required purge air consumption and increases efficiency.
