PCR Moisture Free Air Generator Description of Operation

The PCR dryer employs Pressure Swing Adsorption (PSA) technology to remove water vapor from ordinary compressed air. The inlet shuttle valve directs the wet air into one of the two desiccant chambers where nearly all of the water vapor is removed. The ultra-dry air leaving the desiccant chamber passes through the outlet shuttle valve to the application.

Both shuttle valves contain a wafer-like disk, which “shuttles” back and forth in the valve body based on the pressure differential created by the position of the two-way solenoid valves. A precision orifice in the outlet shuttle disk allows a portion of the dry air leaving the desiccant chamber to be redirected back through the off-line tower, purging it of its accumulated moisture. The purge stream exits the unit through the open solenoid valve directly below the chamber being regenerated. A solid-state timer controls the process by opening and closing the solenoid valves.
