Heatless Desiccant Air Dryer
Presair heatless desiccant air dryer is composed of two twin towers, one set of controlling system and one set of switching valves. In the switching time, one tower is absorbing while the other is regenerating. When absorbing, the compressed air flows through the inlet valve of the absorbing tower. As for the regenerating tower, a portion of dried absorbed air will pass through it and discharge out to atmosphere.
