Drierite Dessicant

click image for a larger view

This anhydrous calcium sulfate dessicant has a cobaltous chloride indicator.

  • Absorbs 6-10% of its weight in water, depending on relative humidity
  • Drierite is an efficient drying agent giving visual indication of the progress of absorption and exhaustion.

Process:

  1. Drierite absorbs moisture
  2. Indicator color changes from blue to rose-red

Regeneration of calcium sulfate (and restoration of blue form of indicator) is accomplished by heating drierite, layered 1 granule deep, for 1 hour at 1200C.
