Drierite™ Indicating Desiccant, 4 Mesh Size, 5 lb

Drierite™ desiccants are made from the naturally occurring mineral, gypsum (calcium sulfate), and are available in several varieties designed to solve all types of drying problems. Drierite™ is an all purpose drying agent for the efficient and rapid drying of air, industrial gases, refrigerants, organic liquids and solids. It is used to maintain a dry atmosphere in storage spaces, vaults, commercial packages, and other enclosures; and for the protection of hygroscopic materials or materials subject to mildew, corrosion, rust, or other deterioration caused by high humidity. Indicating Drierite™ is impregnated with cobalt chloride. Indicating Drierite™ is blue when dry and changes to pink upon absorption of moisture. The color change is pronounced and clearly visible. This makes Indicating Drierite™ valuable when it is necessary to know with certainty that dryness is being maintained and to signal when the drying agent should be replaced. It has the same efficiency as Regular Drierite™, and somewhat greater capacity due to the desiccating effect of the cobalt chloride. It can be regenerated repeatedly for reuse.
