Refrigerant Drying

Refrigerant drying means that the compressed air is cooled, whereby a large amount of the water condenses and can be separated. After cooling and condensing the compressed air is reheated to around room temperature so that condensation does not form on the outside of the pipe system. Cooling of the compressed air takes place via a closed coolant system. By cooling the incoming compressed air with the cooled air in the heat exchanger the energy consumption of the refrigerant dryer is reduced. Refrigerant dryers are used with dew points between +2°C to +10°C and are limited downwards by the freezing point of the condensed water.
