The dew point of a refrigerated dryer refers to the temperature at which the moisture in compressed air condenses into liquid water when it passes through the dryer. The primary function of a refrigerated dryer is to remove moisture from compressed air to prevent condensation and potential damage to downstream equipment and processes.

The dew point of a refrigerated dryer is typically set or designed to achieve a specific level of moisture removal. The exact dew point achievable by a refrigerated dryer depends on several factors, including the design and performance of the dryer, the operating conditions, and the desired level of moisture removal.

Refrigerated dryers typically aim to achieve a dew point between 35°F (1.7°C) and 50°F (10°C). This range is suitable for many general industrial applications where compressed air quality requirements may not be as stringent.

It's important to note that different types of dryers, such as desiccant dryers or membrane dryers, may be required for applications where an even lower dew point is necessary, such as in sensitive processes or industries where strict air quality standards must be met.
