    DESCRIPTIoN Dryer function automatic purge Saving System • Dual tower regenerative desiccant dryers are an economical featured with the level 2 controller, the automatic purge Saving and reliable way to dry compressed air to dew points below the System is designed to save energy (purge air) when pressure-swing freezing point of water (dew points as low as -100°f (-73.3°c) dryers are operated at reduced loads.
  • Page 4 Description of operation – Dryer 3.3.1 models 40 to 3000 w/ Shuttle valve (Refer to Fig. 3-1a.) Compressed air flows through inlet shuttle valve (3) OUTLET to tower (4A) where the air is dried. After the air is dried it flows through outlet shuttle valve (5) and then to the dryer outlet.
  • Page 5 3.3.2 models 4100 to 5400 w/ check valves (Refer to Fig. 3-2a.) Compressed air flows through inlet switching OUTLET valve (3a) (normally open) to tower (4a) where the air is dried. after the air is dried it flows through outlet check valve (5A) and then to the dryer outlet.
