We use an "Inert Gas Cabinet" sold by Stanley Storage Systems (800-523-9462). It's similar to a very large tool box (steel cabinet with wide, steel drawers...ours is 59"H x 30"W x 28"D, but they make two smaller sizes). They make it air-tight by welding the seams and adding a gasketed door to the front. We run a continuous N2 purge through it (fittings are pre-installed). This seems to do the job.

WE USE 3 chamber OF Mc-DRY(MODEL NAME). THE MACHINE CAN REMOVE HUMIDITY FROM PARTS IN THE GENERAL PERIPHERAL TEMPERATURE (MAY BE 25-30;CENTIGRADE). AND IT'S CONVENIENT FOR MAN TO PUT OR TAKE OUT COMPANENT FROM CHAMBER BECAUSE THERE IS NO HOT AIR AND ANY GAS. IN THIS CASE IT'S COOL.BUT IT'S DIFFICULT FOR US TO CONFIRM OR CHECK IT OUT THAT THE COMPONENT IS DEMAGED BY HUMIDITY AFTER SOLDERING THOUGH WE PUT ALL OF THE HUMIDITY SENSITIVE DEVICE IN THE McDRY. I THINK YOU NEED YOU JUDGE. WE BOUGHT IT FROM JAPAN. TEL (0427)49-9751 FAX (0427)44-4521 THE NAME OF PRODUCED COMPANY IS E.R L.T.D
