About Refrigerated Air Dryer
The primary function of a refrigerated air dryer is to remove moisture from compressed air by cooling it to a certain temperature.
This process is based on the principle of heat removal rather than the generation of cold. Heat naturally flows from warmer objects to cooler ones.
The refrigerated air dryer exploits this principle by cooling the compressed air to a temperature lower than its initial temperature, causing moisture to condense and separate from the air.
The air enters the system and passes through a pre-cooler, which is a heat exchanger. In the pre-cooler, the incoming hot air is cooled by the outgoing cold air, reducing the heat load on the evaporator and the refrigeration system as a whole.
After the pre-cooler, the air enters the evaporator, where further cooling and heat removal are achieved using a steaming refrigerant.
In the evaporator, the compressed air is cooled, causing moisture to condense and separate from the air. The air, now free from moisture, passes through a moisture separator, where any remaining moisture is removed by centrifugal action.
