DU-CAL DRIERITE
Stock No.41050
Du-Cal DRIERITE is a higher-capacity desiccant designed for drying air and common gases. It is suitable for drying towers, vent driers and applications where increased moisture capacity is required.
PROPERTIES
Du-Cal DRIERITE is anhydrous calcium sulfate impregnated with a small amount of calcium chloride to increase its absorption capacity. It does not become visibly wet through absorption, because the calcium chloride acts as a catalyst to convert the calcium sulfate hemihydrate to the dihydrate. Du-Cal DRIERITE will not shrink, expand, or disintegrate. It may be regenerated repeatedly and is economical. Du-Cal DRIERITE retains the extremely high efficiency of Regular DRIERITE with the added advantage of a large increase in capacity.
*It should be noted that Du-Cal DRIERITE should not be used for the drying of ammonia, NH3, since ammonia reacts with inorganic chlorides.
