Drierite Desiccants - 23005

Drierite is made from the naturally occurring gypsum (calcium sulfate), and 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.

  • The moisture remaining in gases dried with Drierite at 25° to 30° C is 0.005 mg/L.
  • Organic liquids are dried to the low ppm range.
  • For the drying of liquids, Drierite instantly absorbs 6.6 weight percent water by chemical action, creating the hemihydrate of calcium sulfate.
  • For the drying of gases, Drierite has a water capacity of 10 to 14 weight percent.
  • All forms of Drierite can be regenerated many times for reuse.

Regular Drierite 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, and is economical to use

Indicating Drierite is impregnated with cobalt chloride and is blue when dry and changes to pink upon absorption of moisture. 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.
