Dry Boxes are used for a variety of purposes and in many designs depending on the application - but they are always used to keep the contents of the box dry.
Some dry boxes are used for deep sea diving to depths of up to 30 meters and generally seal to prevent water from entering the box. Other dry boxes hold musical instruments, equipment, or moisture-sensitive products and are also designed with a special seal to prevent moisture from entering.
There are also dry boxes that are used in laboratories or manufacturing plants, particularly electronics manufacturing and circuit board assembly. These dry boxes must maintain a constant dry, inert atmosphere for successful production. In some cases, the dry boxes themselves are constructed from material that is permeable to moisture. Simply sealing the box to create isolation will inevitably lead to the creation and introduction of moisture within the box.
To successfully eliminate moisture levels from dry boxes used in the lab, a continuous stream of Nitrogen gas must be pumped into the container to inert the atmosphere and purge it of water vapor-producing oxygen (See more info on Dry Box Purging with Nitrogen Gas).
Maintaining a steady flow of Nitrogen gas can be costly if you're depending on a gas company to supply you with high pressure N2 gas cylinders. Anytime the chamber is opened, a greater amount of N2 gas is necessary to purge the atmosphere again. It may be hard to predict how much Nitrogen you will need and how quickly you will empty your tank depending on the particular project you are working on. You face the risk of running out of Nitrogen or running your gas costs way up.
One solution to the issue of maintaining the necessary amount of Nitrogen gas for your dry box without worrying about running out or running up your costs is to invest in a Nitrogen Generator. A Nitrogen Generator will produce high purity Nitrogen gas on-site and on-demand. Using a simple process that literally generates N2 gas from the air all around us, a Nitrogen Generator will never run out out of gas and will eliminate your contract with the gas company.
