What is a Dry Cabinet?

In various industries such as semiconductors, optoelectronics, and precision electronics, it is crucial to protect components and materials from moisture and oxidation. Storing these items directly in ordinary environments can lead to damage. To address this issue, nitrogen gas cabinets are used as a protective storage solution.

A nitrogen cabinet storage is a laboratory equipment that utilizes a flow of nitrogen gas to create an oxygen-free environment within an enclosed space. This inert atmosphere protects 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 consist of three main parts. The doors are surrounded by magnetic sealant strips and pressed sealant cotton to ensure airtightness. The pipeline part includes a nitrogen pipeline, nitrogen flowmeter, and nitrogen saving module QDN. The circuit part consists of a power supply, control panel, and power supply box.

The materials used in nitrogen dry box storage vary. Cold-rolled steel with anti-static spray is suitable for ordinary environments, while stainless steel, including mirror and brushed stainless steel, is used in clean rooms or corrosive environments.

The working process and principle of dry nitrogen storage cabinets involve connecting the cabinet to a nitrogen gas source through a regulator. The flow rate and pressure of the gas can be controlled. The gas enters the nitrogen control cabinet through small ports or diffusers located at the top. The humidity conditions required for product storage are determined and set through the control panel.

Once the nitrogen gas flows into the industrial drying cabinet, it displaces oxygen and other gases, reducing the oxygen concentration to the desired level. This creates a stable, oxygen-free environment suitable for storing chemicals, electronics, or biological samples.

Nitrogen continuously enters the cabinet, gradually diluting the air and reducing humidity and oxygen content. The pressure in the cabinet increases as nitrogen is charged, compressing the sealing strip and replacing the original air. It is important to note that the external nitrogen pressure should not be too high and should be adjusted according to the cabinet specifications.

Dry nitrogen storage cabinets have various applications in laboratory settings. They are used for preserving sensitive materials, including chemicals, electronic components, and biological samples, protecting them from moisture and contaminants. Additionally, nitrogen cabinets create oxygen-free environments for chemical reactions that require precise control and accuracy.

In conclusion, Dryzone, a professional dry cabinet dehumidifier supplier, manufactures a dry cabinet, specifically a nitrogen gas cabinet, that is a vital tool in industries where moisture and oxidation can damage sensitive materials. By creating an oxygen-free environment, these cabinets ensure the integrity and stability of stored items. Whether it is for preserving materials or conducting precise experiments, nitrogen cabinets play a crucial role in laboratory settings.
