IDW, Compact Heatless Air Dryer for North
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 2 desiccant columns and use a small portion of the dry air from the column in service to regenerate the other column, thus assuring continuous capability of providing dry air.
