If further moisture removal is needed, look next to actros air dryers. These dryers work by chilling the air, much like your air conditioning system. Remember that colder air holds less moisture than warmer air. The actros air dryer chills compressed air to roughly 33-40°F.

As the air cools, excess water vapor condenses back into a liquid. The liquid collects in a water trap and is removed through an automatic drain valve. The dry air is then reheated to room temperature before it reenters the production lines.

Compressed air that is dried by this method has a dew point (the temperature at which condensation will form) between 33-40°F, which is low enough for the majority of industrial compressed air applications.
