    Good to know. We get routinely in the upper 90s (rH) during the summer rainy periods; we’re surrounded by forest and brush. Too bad the conventional dry pacs don’t have color indicators to let you know when they’re saturated/used up.

    Yes that’s way I wanted to try this one it changes color from blue to a pink color and can be regenerated by baking.

    So how is the Drierite working, GKU? Form the look at the label, it’s a Calcium sulfate instead of Silica gel. Looks porous, too, which might make it work faster.

    Is the baking temperature to recharge it in the 350 degree F range?

    To super-dry, I’m thinking a 2-3 inch diameter pvc pipe, maybe 24 inches long, filled with desiccant. It would be easy to make and feed to the pump intake.

    It would be a lot better to make/find a high pressure desiccant rig on the pump output side.

    Hi bogman,

    I haven’t tried it yet, when it came in when I just refilled my pumps with Hill packs before hand.

    For the regeneration of Indicating DRIERITE, 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 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.

    The rate at which it adsorbs can be adjusted by using a different mesh size when ordering, from 4-20 mesh. I ordered and got the 8 mesh thinking it has about the same surface area as the Hill dry pack granule. I would think that the smaller mesh will absorb at a faster rate but it may need to be regenerated more frequently ?

    I would try and look for something clear instead of PVC ?

    I will be posting its performance here as soon as I can.

    That’s almost 8 inches right there SEcoda, you’re telling me yours is larger than that? We’re going to have to call you Lex Steele from now on. Warning do not google lex steele if you’re scared of getting your eyes poked from across the room.
