Drierite Dessiccants

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.

Regular Drierite®

Regular Drierite® is anhydrous calcium sulfate. It is of neutral pH, constant in volume, chemically inert except toward water, insoluble in organic liquids and refrigerants, non-disintegrating, non-wetting, non-toxic, non-corrosive, non-channeling, generally recognized as safe (GRAS) by the FDA, not regulated by OSHA, economical to use, and can be regenerated repeatedly for reuse.

Indicating Drierite®

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.
