Dry-O-Lite Chemical Drying Agent from Van Air-Image

Dry-O-Lite, the industry-leading deliquescent desiccant, is a chemical drying agent specifically formulated for Van Air single tower compressed air dryers and natural gas Pipeline Dryers. Dry-O-Lite is a dense hygroscopic tablet that absorbs water vapor from streams of compressed air or gas. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the desiccant is fully consumed.

In a properly sized Freedom Dryer or Pipeline Dryer, Dry-O-Lite will establish a relative humidity of 55%, which equates to a dew point approximately 20°F lower than the temperature of the compressed air or gas at the inlet of the dryer.
