SPBS SERIES

Externally Heated Blower Purge Regenerative Air Dryer

115-3530 CFM

Compressed air enters the dryer and is directed to a tower by the inlet valves. It then proceeds up through the tower, gives up its moisture, then exits through the outlet check valve. A regenerative blower creates a purge stream that is heated by a circulation heater increasing it’s moisture holding capacity while transferring heat to the desiccant bed.

The moisture is picked up by the heated purge air, and exits to the atmosphere through the purge exhaust valve and muffler. The drying and regenerating cycles occur simultaneously for 4 hours. The regeneration cycle begins with 2.5 hours of heating and 1.4 hours of cooling, then the tower repressurizes before the inlet valves invert and the process starts again.

Blower Purge dryers use wet ambient air for regeneration that can cause dewpoint to fluctuate with seasonal ambient conditions. The standard Tri-Mode operating feature allows the SPBS dryer to overcome seasonal dewpoint spikes.
