Why is it necessary to dry compressed air?
The atmospheric air drawn into a compressor is a mixture of gases that always contains water vapour. However, the amount of water vapour that air can carry depends on the temperature. As air temperature rises, which occurs during compression, the air’s ability to hold moisture increases also. When the air is cooled, its capacity to hold moisture reduces which causes the water vapour to condense. Removing the moisture from the compressed air not only prevents costly breakdowns and production downtime, but also keeps maintenance and repair costs to a minimum.


A calibrated solenoid valve adjusts the size of the refrigerant compressor’s compression chamber according to the volume and temperature of the compressed air to be cooled. This means that the compressor uses only as much energy as necessary to meet actual cooling requirements.

Energy-saving dryers from Kaeser enable significant savings all day, every day. For example, at 40 % airflow they consume only 43 % of their nominal energy requirement. This results in significant annual savings of several thousand Euro compared with conventional compressed air drying systems.

The air/air and air/refrigerant stainless steel plate heat exchangers were specially developed for use in refrigeration dryers. Generously sized copper piping ensures minimal pressure drop and saves additional energy as a result.

Every Kaeser energy-saving dryer is EN 60204-1 compliant and is tested for electromagnetic compatibility in accordance with applicable EMC standards. Unlike equipment conforming to VDE 0700, TG-TI series dryers meet the demanding requirements associated with industrial applications.
