What is pressure dew point PDP?

Pressure Dew Point (PDP) is a measurement used in the field of compressed air systems to indicate the level of moisture content in the compressed air. It represents the temperature at which the moisture in the air begins to condense or form dew as the pressure decreases. The PDP is expressed in degrees Celsius (°C) and is typically measured at the operating pressure of the compressed air system. It helps determine the level of moisture removal required to achieve a specific level of dryness in the compressed air. By maintaining a pressure dew point below the desired operating temperature or application requirements, the risk of condensation and moisture-related issues can be minimized. This is particularly important in applications where moisture can cause equipment damage, corrosion, or affect the quality of end products. Monitoring and controlling the pressure dew point of compressed air is essential in various industries, including manufacturing, food and beverage, pharmaceuticals, electronics, and painting/coating processes. It ensures the efficient and reliable operation of pneumatic systems while preventing moisture-related problems.
