Pressure dew point (PDP) is the temperature at which water condenses in a pressurised gas – for example in a compressed air system. If the pressure of the gas increases, the dew-point temperature also increases. The temperature at which the water vapor in gas then condenses is dependent on the absolute moisture content and pressure of the gas.Dec 4, 2019 · Enter the air temperature (C) and wet bulb or dew point temperature or RH.
