What is the difference between the pressure dew point and the atmospheric pressure dew point for IDG series air dryers?

The atmospheric pressure dew point is the temperature at which condensation begins to occur when air is cooled under atmospheric pressure.
The pressure dew point is the temperature at which condensation starts to occur when compressed air is cooled under a certain pressure.
As the dew point also changes as the pressure changes, refer to the “Dew Point Temperature Conversion Chart” in the IDG series catalog for instructions on how to convert the dew point.
