Drierite® is an all purpose drying agent for the efficient and rapid drying of air, gases, refrigerants,
liquids and solids. It is composed of naturally occurring Calcium Sulfate, impregnated with Cobalt Chloride. Drierite® is blue when dry and changes to pink upon absorption of moisture.
Drierite® can be regenerated simply by heating in
an oven where it will return to its normal blue color.
