The Van Air Systems HLSXA Series Explosion Proof Heatless Desiccant Air Dryer delivers extremely dry compressed air in the harshest and most challenging operating environments where safety and performance are of central importance. HLSXA dryers are explosion-proof and have been designed to operate in areas classified as hazardous, Class 1 Division 1, Groups C & D, per the National Electric Code.

HLSXA dryers remove water vapor from saturated compressed air through the process of pressure swing adsorption. Each dryer consists of two desiccant columns. While one column is drying compressed air, the other column is regenerated by using a portion of depressurized purge air. During this process, the flow of process and purge air is automatically and continuously switched between the two desiccant columns by an integrated timer. 

Note: HLSXA dryers are only for compressed air service.
