In semiconductors, optoelectronics, precision electronics, and other industries, many components and materials will be affected by moisture or oxidation when they are directly stored in ordinary environments. The physical structure of nitrogen N2 is stable, and the gas with a lower cost is just suitable to be used as the protective gas of the product. Thus, the nitrogen gas cabinet can protect the products that need to be stored in a nitrogen atmosphere.

A nitrogen cabinet storage is a type of laboratory equipment that uses a flow of nitrogen gas to create an inert, oxygen-free environment within an enclosed space. The purpose of this is to protect sensitive materials or samples from exposure to oxygen or other contaminants that may negatively affect their stability, reactivity, or accuracy.

The Dry Nitrogen Gas Cabinets are Mainly Composed of Three Parts:

In the part, the surrounding of each door is composed of magnetic sealant strips, and there is also pressed sealant cotton around the glass to ensure the overall airtightness of the cabinet;

The pipeline part, nitrogen pipeline-nitrogen flowmeter-nitrogen saving module QDN-pipe enters the dry nitrogen storage cabinet;

The circuit part mainly includes a power supply, control panel, and power supply box.

The Materials of Nitrogen Dry Box Storage

Cold-rolled steel plus anti-static spray can meet the storage of products in an ordinary environment;

Stainless steel (also divided into mirror and brushed stainless steel, click here for more about stainless steel desiccator cabinet ) is mainly used in clean rooms of class 100 and above or in corrosive environments;

Working Process and Principle of Dry Nitrogen Storage Cabinets

To create the nitrogen atmosphere, the dry nitrogen storage cabinets is connected to a nitrogen gas source, usually through a regulator that allows the user to control the flow rate and pressure of the gas. The gas is then fed into the cabinet through one or more small ports or diffusers located at the top of the cabinet. So we need to find out the humidity conditions required for product storage and then set the humidity value through the control panel.
