Absorbent Desiccant

Dry-O-Lite Deliquescent Desiccant

Deliquescent DesiccantDry-O-Lite, the industry-leading deliquescent desiccant, is a chemical drying agent specifically formulated for Rapid Prep’s single tower compressed air drying system and natural gas Pipeline Dryers.

Dry-O-Lite desiccant is a dense hygroscopic tablet that absorbs water vapor from streams of compressed air or gas. The surface of the Dry-O-Lite desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the absorbent desiccant is fully consumed.

In a properly-sized Freedom Dryer or Pipeline Dryer, Dry-O-Lite desiccant 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.
