Comments about Drierite 23001 Indicating desiccant; twelve 1-lb packs/carton:

I disagree with the below statement
"The product has a good product life cycle and can be used repeatedly for an extensive period of time".
I can get 2 reuses out of it before the color stays pink. Following the baking refresh directions and not to happy with it. But I need it, will look for other brands to try.

      My qualm with this product is that C-P only sell it in very very large quantities. For my application, I require only 1-2kg. A box of 12lb of the stuff isn't all that useful.

        • Q:

          After one use of the 1-lb pack, it was place an oven to regenerate until blue again. Directly from the oven, it was replaced in the jar it came with, sealed, and placed in a dessicator. Why did it turn from blue to pink in the dessicator?

            A:

            It could be that the desiccant was not fully regenerated. Or perhaps there was moisture in the desiccator where the desiccant was placed. For the regeneration, the granules may be spread in layers one granule deep and heated for 1 hour at 210° C or 425° F. The regenerated material should be placed in the the original glass or metal container and sealed while hot. The color of the Indicating DRIERITE may become less distinct on successive regenerations due to the migration of the indicator into the interior of the granule and sublimation of the indicator.

            A:

            Drierite does not have a limit for regeneration, however over time the colored indicator can start to move into the center of the desiccant, which will make the blue/pink color not as intense. The product will still perform correctly, however for convenience this may be the time to purchase new desiccant.

            A:

            To find to the volume of a container the formula is pi x r^2 x H r=radius, H=height. That will give you cubic millimeters. You can convert that to cubic centimeters. One cubic centimeter is equal to one cubic milliliter. That should give you the volume.

          I need to dry Drierite that is in my gas drying unit. Do I need to empty it from the unit to dry it or can I stick the whole thing in an oven or dryer?

            A:

            We suggest placing it on a cookie sheet and then putting it in the oven to "recharge". This ensures each grain has good exposure to the heat and releases the moisture it contains.

          • STAFF EXPERT

            A:

            The amount of desiccant needed is dependent upon the volume of the container you are trying to dehumidify, and the amount of humidity in the environment before adding the desiccant to it. Drying capacity of the indicating Drierite is 10-14% of its weight in water and gases.
