I worked maintenance in a refinery on the left coast. One of our jobs was to load desiccant in fuel driers. It came in 1500# sacks of pellets a little smaller than the size of dishwasher pellets. We would load in maybe 20 such sacks every 4-6 weeks. Basically the "driers" were big vertical tanks with funnel shaped bottom sections, the bottom was filled with gravel about 1" in diameter and the desiccant pellets set on the gravel, the diesel or jet fuel went in the tank though a distributor header about 6ft down from the top of tank and out an over flow on top of the tank. The operators would regularly go open a valve on the very bottom of the tank and drain the water off into the plants sewer system to get treated at the effluent.
If you let one of those pellets lay somewhere it would form a small pool of water around it. Guys would take some home and put it in their boat cabins and engine enclosures, RVs etc. They would perforate a coffee can and then keep it filled with pellets and set on about 1" spacers in a pan. Water would drip out of the coffee can into the pan, which they would dump about once a month. Every time we loaded desiccant we set some aside for home use. Even plant management would get some.
Point is, if I live in a humid area and used desiccant to keep a enclosure dry, I would set it up over a drip pan and drain the drip pan regularly.
