A hermetically sealed container, closed in a normal ambient atmosphere, would require approximately four ounces of DRIERITE for every 10 cubic feet of free volume to dry the air in the container. At more extreme conditions (100° F and 100% R.H.) eight ounces of DRIERITE would be required.

How do you use DRIERITE desiccant?

Commercial Grade and Du-Cal DRIERITE Exhausted Commercial DRIERITE or Du-Cal DRIERITE should be spread about 1 inch deep in shallow pans and heated in a oven at 450° F or 230° C for 2 hours to achieve complete dehydration. The regenerated material should be placed in the original container and sealed while hot.

How does DRIERITE work?

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. This increased capacity is due to combined chemical and capillary action.
