PD-Series Gas Dryers Performance

The Performance curves to the left are based upon an inlet dew point of 20°C. For conditions higher than ambient temperature, it is assumed that the first half of the dryer will be used to bring the dew point down to ambient. For this reason, read the value of the next shorter dryer. For example, a stream with an initial dew point of 50°C, flowing at 2 slpm; a PD-50T-24 should yield an outlet dew point of -6°C, the performance of the 12" unit.
