HDT Desiccant dryers
In some industry (electronics, pharmaceutical, food preparation, pneumatic conveying, etc.) or for installations with external pipe work, a pressure DewPoint of +3°C from a refrigerant dryer is not sufficient. For these applications, a heatless adsorption dryer is required supplying compressed air at a pressure DewPoint of down -70 °C.
The HDT heatless adsorption dryers consist of two parallel vessels filled with adsorption material (molecular sieve). While compressed air is dried in one tower, the second saturated tower, having just come off line, is regenerated.
The dryers are supplied with 0.01 micron oil removal filter (with automatic drain) on the inlet and a 1 micron dust filter on the outlet. Both filters are fitted with a pressure differential gauge, offer easy access for maintenance and are contained within the dryer footprint.
The proper functioning of the dryer is constantly controlled and monitored by the electronic controller.
