Steve, thanks. I think I need a cabinets for the weekend jerky making as supplement income... jk -----Original Message----- From: Stephen R.

I'm like you, the physics make me feel a little lightheaded too. But, we fairly recently bought some desiccant cabinets from McDry, and they keep the humidity down to 4% inside the cabinets...and that's here in Oklahoma, we see humidity levels at 80-90% quite often here. McDry's claim to fame is that a desiccant cabinet will actually pull moisture out of devices over a period of time...something that dry nitrogen cabinets can't do. You can check their charts out at: http://www.seikausa.com/mcdry/page5.html I actually think that you could make beef jerky inside these cabinets...hehehe. They are a little pricey, but when you consider the costs of inerting a cabinet with nitrogen, and the added aspects of a desiccant type system, I think they're worth it. With these cabinets all you do is plug them into a standard receptical, and forget about it. The desiccant is self regenerated by the system... -Steve Gregory- << Anyone out there ever considered drying moisture sensitive devices by lowering the pressure in a storage vessel? It is difficult to achieve 40°C and less than 5%RH when ambient RH is 50-60 percent. So, someone called and asked how long he would need to keep the parts at a pressure equivalent of 80,000 ft above sea level, temperature at room ambient to dry out parts. No one here had considered it before. The physics made me feel like I was at altitude.
