Sullivan Palatek SPBS115 Externally Heated Blower Purge Regenerative Air Dryer

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 and 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 hr. The regeneration cycle begins with 2.5 hr of heating and 1.4 hr 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 dew point to fluctuate with seasonal ambient conditions. The standard Tri-Mode operating feature allows the SPBS dryer to overcome seasonal dew point spikes.
