HPET dryers (high pressure refrigerated compressed air dryers) operate according to the same principle as refrigeration dryers. While standard refrigeration dryers are designed for a maximum pressure of 16bar, an HPET dryer is able to process pressures up to 50 bar. The pressure dew point also lies at +3°C. The available volume flows range between 0,85m³/min and 92,5m³/min.
The user can choose between an air cooled and a water cooled version.
