Section 6: Operation Operation Background / Function of the dryer Detailed Operational Description - Digital Display Controller • Refer to detailed operational schematics, The dryer is designed to provide a smooth, controlled and uninterrupted delivery of dry compressed air. Wet air passes through a pre-filter and travels figure(s) 6.3 - 6.8. -
Page 25: Start-Up Procedure
Section 6: Operation • Purge loss may be reduced during periods of low or no air demand. The Energy Management Feature (EM) may be utilized in this case. A detailed description is given in Section 7. • For remote indication of any electrical faults, the Alarm Contacts may be utilized to send a signal to a light or remote service panel. Further details are given on page 23. -
Page 26: Operational Schematics
Section 6: Operation Figure 6.3: Initial Pressurization (Power Off) • With power off to the dryer, both towers pressurize to line pressure. The N.O., 3/2 solenoid valves are de-energized and therefore, are in an open position. The air supply through the solenoid valves forces the exhaust shuttles into a closed position, and the dryer remains air-tight. •... - Page 27 Section 6: Operation Figure 6.4: Stage 1: Left Tower Purging, Right Tower Drying • After an initial 40 second delay the left solenoid is energized and therefore switches spool position releasing the compressed air behind the exhaust shuttle. This allows the left exhaust shuttle to open allowing air to rush from the left tower out of the silencer as it depressurizes. For 120 seconds, a bleed of dry air from the outlet of the on-stream (right) tower is directed through the left purge orifice and down through the left tower to regenerate the off-stream (left) desiccant bed.
- Page 28 Section 6: Operation Figure 6.5: Stage 2: Repressurization • At completion of Stage 1, the left solenoid is de-energized and switches spool position allowing the air supply through the solenoid to close the left exhaust shuttle. The left tower then repressurizes for a 34 second period. •...
- Page 29 Section 6: Operation Figure 6.6: Stage 3: Left Tower Drying, Right Tower Purging • At the completion of Stage 2, the right solenoid is energized and therefore switches spool position releasing the compressed air from behind the exhaust shuttle. This allows the right exhaust shuttle to open allowing air to rush from the right tower out of the silencer as it depressurizes. For 120 seconds, a bleed of dry air from the outlet of the on-stream (left) tower is directed through the right purge orifice and down through the right tower to regenerate the off-stream (right) desiccant bed.
