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"

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.

same job.  Do I need to plan some maintenace on it, calibration, is there a
used market for that what are the compagny who sold them.

  So many question...hehehe

Thanks You

Yannick
