HDT

The HDT range is used in situations where a refrigeration dryer dew point is insufficient under ISO 8573.1. This includes electronics, pharmaceuticals, foodstuffs, pneumatic conveying industries, or in installations with low ambient temperatures. With its cold-regenerated adsorption dryer technology, a dew point down to -70°C can be achieved. These dryers consist of two parallel tanks filled with adsorbent material (molecular sieve): while one column dries the air, the other is regenerated with a small part of the already treated air. Units are equipped with an inlet de-oiling filter and an outlet anti-dust filter. The DDC15 electronic controller (industry 4.0 ready), available on the entire range, provides an intuitive interface for monitoring operation and scheduled maintenance. It manages time-based regeneration cycles (or using optional dew point probe).
