For components storage, RP-system from
Mistubishi Chemical would work... you may need a vacuum meat sealer to heat seal
the aluminum foil bag (good for beef too)...there are two kinds of RP
system. Make sure you get the right one (type
A)...

Hi Yannick!
We use the McDry cabinents here,
and they work great. The humidity level is kept around 4% RH, and that's not
too bad..you know, it never gets hot or humid here in Tulsa, Oklahoma (GRIN).
Also, when I start running low on beef jerky, I'll just throw a few slabs of
beef in for a few days...(JUST KIDDING)
You may think at first they are
expensive, but when you figure the costs of plumbing nitrogen, and the
on-going expense of using the nitrogen, the costs really aren't that
bad.
There's virtually no maintenance on them, as they self-regenerate
the dessicant in them. You should send the humidity meter out annually for
calibration, McDry will do that for you. In fact, they send you a notice when
yours is due for calibration.
Camera dry boxes are kind of small, and
the ones I've seen don't go down to the low humidity levels that the dry boxes
for electronics do.
One good thing about desiccant cabinents, is that
you can avoid baking if the components are left in the dry box long enough.
According to the data, they will actually "de-humidify" the components
bringing the absorbed moisture down to a level below where "pop-corning" or
micro-cracking can occur.
There's two companies that I know of that
make these desiccant dry boxes. One is McDry (the ones I use), and the other
is a company called Toyo Living. This last APEX show is the first time I've
seen Toyo Living dry boxes. They supposedly are cheaper than McDry, and also
contain heaters that work in conjunction with the desiccant. Here's the links
to both
companies"

RE: [TN] Dry Cabinet
Yannick,
What will you be using the dry
cabinet for?
What level of humidity/dryness must be
maintained?
Calibration, maintenance etc will depend on the unit you
buy.
Let us know your application so we can give more
info.

on it, calibration, is there a
used market for that what are the compagny
who sold them.
So many question...hehehe
Thanks
