The compressed air is directed into the refrigeration dryer for processing,
and pre-cooled in the air/air-heat exchanger. This pre-cooling takes place
in a counter clockwise flow to the escaping, cooled compressed air. This
is accomplished without any additional requirement for energy. Further
cooling to the pressure dew point occurs in the cooling chamber / airheat exchanger that is cooled by a cooling agent circuit. During the entire
cooling process, the moisture escapes as condensate and is automatically
dispensed. The processed compressed air is reheated by the discharged
compressed air in the air/air-heat exchanger.
The RENNER refrigeration dryers work environmentally and compatible
with completely ozone harmless cooling agents R134a and R407c.
Electronic control of the refrigerant dryer
The electronic DDS3 controller is a micro-controller specially developed for
compressed air dryers with the
following functions:
- Pressure dew point indicator
- Control condensate solenoid valve
- Automatic fan control.
Optional – condensate drain
Level controlled condensate drain with ball valve for easy maintenance.
Control DDS5 with alarm contact for dryer.
