How it works

Compressed Air will firstly enter the pre-cooling unit (15) for preliminary cooling, then enter the heat regenerator (1), exchanging heat with the returned finished air, which reduce the temperature of the compressed air. The condensates will be discharged out of the machine. Later, the compressed air enters the evaporator (2), exchanging heat with the coolant to further reduce the temperature of the compressed air, thus achieving the designed dew point.

The compressed air is cooled step by step through pre-cooling unit (18 or 19), heat regenerator (1) and evaporator (2), after that, the vapour in the air will be condensed into water drops. The liquid water will be separated through gas-liquid separator (3).

The dry and cooled air, through the gas-liquid separator (3), will be passed to another process in the heat regenerator (1), heated up before leaving the dryer, so that reduce the Relative Humidity in the air.

Reverse flow is better heat exchange performance

High quality and efficient thread tubes or light tubes ensure a professional thermal conduction index, while the reverse flow heating in the heat exchanger will be better energy-efficient and stable than the typical flow type.

Professional classification of the Operation conditions

To ensure the efficient and stable running as well as energy saving of the refrigerated dryer under different conditions, HANFILTER refrigerated dryers are classified, as per the customers' needs and actual conditions, as: high inlet temperature air-cooling type, high inlet temperature water-cooling type, regular inlet temperature air-cooling and water-cooling types.
