Compressors Air Dryers (Heatless)

• Extensive Mimic display  
• Energy Saving Purge Economiser 
• Filters Autodrain Valves  
• 35 Sales & Service outless across the World

Highlights
Purge Economiser : By setting a switch in the controller at a percentage of maximum flow, the controller will close the purge valve when sufficient Purge air has been used. This reduces purge loss according to air usage. The purge loss, Which is 14% normally reduces to as low as 5.6%.

No pressure spike : During changeovers ensures long desiccant part of the Dryer, and not as an accessory.

Pre/Oil Filters are fitted with automatic Drain Valve as an integral part of the Dryer, and not as an accessory.

Principle of Operation - Coldspell
Warm compressed air enters the air / Air Heat Exchanger where it is precooled by outgoing cold dry air. Pre-cooling makes it possible to use a smaller (More Economical) refrigeration Unit. The pre-cooled air enters the air to Freon Heat Exchanger where it is cooled down to +3oC. At this 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 surface or Sharp corners that collect dust, dirt or oil residue. Any dust, dirt or out will be washed from the air system along with the condensed moisture at the De-mister.
