Working Principle
It operates on the principle of cooling the compressed air to a temperature where the moisture in the air condenses into water. This condensed water is then separated from the air and discharged, while the dry, compressed air is sent downstream for use in the system.
Cooling Process: Compressed air enters it and passes through a heat exchanger, where it is pre-cooled by the outgoing dry air. This pre-cooled air then passes through a refrigeration circuit, where its temperature is further reduced to around 3°C to 7°C (37°F to 45°F). At this temperature, the moisture in the air condenses into liquid water.
Water Separation: The condensed water is separated from the air through a mechanical separator. The separated water is discharged from the system using an automatic drain valve, ensuring that no liquid water remains in the air stream.
Reheating: Before leaving the drier, the cold, dry compressed air is reheated using the incoming warm air in the heat exchanger. This step prevents condensation from forming in the piping system as the air returns to ambient temperature.
