Air Dryers for Manufacturing & Process Industry -Image

Heated Purge Desiccant Dryers

Van Air HP series externally heated regenerative compressed air dryers provide a low -40°F dew point for superior air line moisture protection, while offering the efficiency of convection-heated desiccant regeneration. These are ideal for general manufacturing and process industry applications.

All Van Air HP series dryers feature: an isolated external heater for an extra measure of safety; Interlock Logic valve sequencing, for the most reliable tower cycling; and heatless back-up mode, for uninterrupted service while the heater is being serviced.

Principle of operation: Wet compressed air enters the inlet valve and is dried as it flows through a bed of adsorbent desiccant. Dry air exits the outlet valve of the dryer. A small portion (8%) of the outlet air is redirected through the external heater and downward through the off-stream tower to regenerate the desiccant. Wet air is exhausted through the purge valve. The eight-hour NEMA cycle includes four hours of drying, three hours of heating and one hour of cooling per tower.
