Air Dryers – Heatless Regenerative Dryers

Regenerative desiccant drying systems provide the greatest level of drying capability amongst widely available drying technologies. The ID and IDW series are heatless units that produce atmospheric dew points of -22°F (-30°C) and below and ISO 8573-1 moisture classes of class 3 and better. Heatless designs alternate between two desiccant columns and use a small portion of the dried air from the column in service to regenerate the other column, thus assuring continuous capability of providing dried air.
