Compressed Air Dryers (Heatless) by Sumved International

We offer Compressed Air Dryers (Heatless) which are the simplest form of desiccant type gas or air dryer (drier). Our range is perfect for achieving a dew point of -40°C for compressed air systems and other gas and air dryer (drier) applications. The process by which our dryers work involves wet incoming compressed air after passing through pre filter passes through the slide piston valve assembly and is directed towards chamber I where the compressed air passes upward through the desiccant. Compressed Air drying takes place by adsorption. Dry Compressed air from chamber I then passes through the Check valve assembly and then through the after-filter to the application or work area.

Purge Economiser:

By setting a switch in the controller at a percentage of maximum flow, the controller will close the purge valve when sufficient purge air has been used. This reduces purge loss according to air usage. The purge loss, which is 14% normally reduces to as low as 5.6%.

No pressure spike :

During changeovers ensures long desiccant life.
