compressed air enters the Air/Air heat exchanger where
it is precooled by outgoing cold refrigerated air. Pre-cooling
makes it possible to use a smaller (more economical)
refrigeration Unit. Then the pre-cooled air enters the
Air to Refrigerant heat exchanger where it is cooled
down to +3° C. At this cool temperature, water condenses
into liquid droplets, which are removed from the air
stream by a very efficient Demister and automatically
discharged to drain by a Trident Automatic drain valve.
The cold dry compressed air passes back through the
secondary side of the Air to Air heat exchanger where
it is reheated by the incoming warm air. Reheating the
outgoing compressed air increases the volume of the
air enabling it to do more work and it also prevents
downstream pipe sweating. Trident heat exchanger has
no extended surfaces or sharp corners that collect dust,
dirt or oil residue. Their self cleaning smooth surface
tube in shell and tube design will maintain the same
heat transfer efficiency through out the dryer's life.
Any dust, dirt or oil will be washed from the air system
along with the condensed moisture at the De-mister.
