Operation
The process of drying compressed air by GLOBAL refrigerant air dryer goes through the following stages:
Step 1:
Compressed air enters the GLOBAL refrigeration dryer, loaded with moisture, passes through the air-to-air heat exchanger and is pre-cooled by the chilled out going compressed air prior to entering the air-to-refrigerant heat exchanger.
Step 2:
The pre-cooled air is channelled towards the second phase of cooling, where it reaches below 3°C through the air-to-refrigerant heat exchanger. At this moment, the moisture contained in the compressed air in the form of vapour condenses and is dragged to next stage by gravity and airflow.
Step 3:
The compressed air, which was cooled during the previous step, goes through a high efficiency separator which separate out the water from the compressed air. The water is then discharged from the system by the timer controlled automatic drain. The compressed air now free fo all condensation, goes on to the next stage.
Step 4:
The chilled and dry compressed air then leaves the high efficiency separator, passes through the secondary side of the air-to-air heat exchanger and gets reheated by the in-coming compressed air before leaving the dryer.
