What You Need to Know About Dew Point and Drying

Dew point is the temperature at which the moisture in a gas will condense. More specifically, it is the temperature at which the vapor pressure of a gas equals the saturated vapor pressure.

As it relates to drying plastic pellets, the gas in question is air. The more parts per million of water particles in the air, the higher the vapor pressure, and consequently, the higher the dew point. As the dew point of air is reduced, its ability to take in moisture is increased.
