Standard Nitrogen Control system

N2HT

Gas concentration control system,Oxygen concentration monitoring system

The Bossmen Standard Nitrogen Control Unit is designed specifically for the semiconductor industry, featuring a stainless steel nitrogen cabinet that meets international semiconductor drying and cleanliness standards, such as IEC-TR-62258-3. This standard clearly states that the storage environment for wafers and bare die must maintain a nitrogen concentration of at least 99%, with humidity controlled between 30% RH and 7% RH to prevent electronic damage caused by improper humidity levels.

The Bossmen Standard Nitrogen Control Unit not only precisely regulates humidity but also offers advanced electrostatic discharge (ESD) elimination to effectively prevent dust generation and adhesion, ensuring a clean storage environment. With a high-efficiency filtration system, it further addresses dust interference, meeting ISO14644 Class 6 cleanroom standards.

Additionally, the system is equipped with an energy-saving feature that automatically stops nitrogen filling when the environmental humidity reaches the set standard, reducing nitrogen consumption and saving up to 80% in energy.

The Bossmen Standard Nitrogen Control Unit provides a stable, energy-efficient, and clean environment for semiconductor storage, ensuring product quality and production efficiency.

Application

Electronics Manufacturing: In semiconductor production, display manufacturing (such as LCD, OLED), and PCB assembly, the Standard Nitrogen Control Unit maintains a low-oxygen environment to prevent oxidation and damage to electronic components. For example, during soldering, nitrogen is used to prevent metal oxidation, ensuring high-quality soldering.
Pharmaceutical Industry: In drug manufacturing and storage, the Standard Nitrogen Control Unit maintains an oxygen-free environment to prevent oxidation of certain drugs or chemicals. This is particularly critical during the storage and transportation of biologics, vaccines, and other sensitive products.
Chemical Industry: In some chemical reactions, the Standard Nitrogen Control Unit creates a low-oxygen environment to prevent unwanted oxidation reactions or by-product formation. Nitrogen is used to control the reaction atmosphere in high-precision chemical synthesis processes, improving yields and maintaining reaction stability.
Metal Processing: In metal heat treatment, welding, and coating processes, the Standard Nitrogen Control Unit prevents metal surface oxidation, ensuring that the surface quality of metals remains intact. For example, nitrogen prevents oxidation during steel heat treatment or aluminum alloy processing, maintaining the metal’s mechanical properties.
Aerospace: In spacecraft atmospheric control, nitrogen is used to replace oxygen, creating a stable working environment and preventing oxygen from damaging high-precision equipment.
Laboratories and Research: In some laboratories, particularly in chemical, physical, or biological research, the Standard Nitrogen Control Unit creates an oxygen-free environment to prevent oxygen from interfering with experiments. Nitrogen is used in certain catalytic reactions to maintain a pure reaction environment.
Optical Manufacturing: In the manufacturing of optical lenses and laser equipment, nitrogen controls oxygen levels to prevent oxidation of optical materials, ensuring product quality. This is especially crucial for high-precision optical devices such as microscopes, lenses, and laser components.
Medical Equipment and Applications: In some medical devices, the Standard Nitrogen Control Unit maintains a stable atmosphere to prevent oxidation or bacterial growth. For example, medical instruments and testing equipment require a low-oxygen environment during operation to ensure optimal performance.
Freezing and Cold Storage: In some cold storage facilities, nitrogen is used to create an oxygen-free environment, extending the shelf life of food or pharmaceuticals, particularly in long-term storage.

In summary, the Standard Nitrogen Control Unit is applicable across various industries that require control of oxygen concentration or atmospheric conditions. Its use spans from electronics manufacturing and chemical reactions to aerospace and medical fields. The inert properties of nitrogen make it an ideal choice for creating stable, oxygen-free environments.
