I wind up with a lot less drying out that way.
As for humidity, the welders and garage shops often have desiccant in the lines of their air compressors and often trade the desiccant beads out with fresh stuff that gets dried out in their welding rod warming ovens. I think the ovens run about 180 degrees f to drive the moisture out of the coatings on the welding rods and also out of the desiccant.
Perhaps there is a need for input air dryers for oxycons using large buckets of desiccant?

That's a great idea for bead release.
The larger oxygen systems, like the OnSites, require an air dryer to be used. Oxygen concentrators pass such a quantity of air (only a small fraction of the air passed through the machine comes out as oxygen) that dessicant air dryers aren't economical, so you need a refrigerated air dryer.
I've got my oxygen concentrators in a box that keeps them from breathing their own exhaust, and I've got a heater in the box that kicks on when it's within 5 degrees of freezing. If it was more humid here, I'd run a dehumidifier in the summer. Medical units are made to deal with a certain amount of humidity, so I don't think that the expense of a refrigerated air dryer is worth it, but I'd be interested to read any hard data on input humidity vs. output purity (and whether or not an enclosure with a dehumidifier would sufficiently solve any problems).
