Working Principle of a Nitrogen Generator

This 3 m³/h Mini Nitrogen Generator for Welding typically uses carbon molecular sieves as the adsorbent. The adsorption rates of oxygen and nitrogen by carbon molecular sieves differ significantly; in a short time, the adsorption rate of oxygen far exceeds that of nitrogen. This characteristic is utilized to achieve oxygen-nitrogen separation. The adsorption capacity of carbon molecular sieves for oxygen decreases as the pressure decreases; reducing the pressure allows for desorption, thus regenerating the carbon molecular sieve. Furthermore, carbon molecular sieves also have the ability to adsorb carbon dioxide and moisture, and desorption is relatively easy.

Applications

3 m³/h Mini Nitrogen Generator for Welding is based on pressure swing adsorption (PSA) technology, can continuously produce high-purity nitrogen on-site, primarily for isolating oxygen and preventing oxidation. Their applications are wide-ranging: Welding: Improves weld quality and prevents solder joint oxidation;
Provides a protective atmosphere for SMT assembly and semiconductor packaging in electronics manufacturing;
Ensures material density in metal processing (powder metallurgy, 3D printing);
Used in the automotive industry for tire nitrogen filling and component protection;
Modified atmosphere packaging in food, explosion-proof purging in chemicals, and as a carrier gas in laboratories.

Effectively reduces enterprise gas costs and ensures process stability, making it an ideal solution for small- to medium-scale production that balances economy and efficiency.

FAQ

Q: What is the required standard purity for nitrogen used in welding?
A: 99.99% is sufficient for routine welding. For precision electronics and lithium battery welding, we can customize 99.999% ultra-high purity to prevent weld oxidation and porosity.

Q: What are the standard flow rates?
A: We have in-stock specifications of 1, 3, 5, 8, 10, 15, and 20 cubic meters. Customization of all flow rates, pressures, and purities is available.

Q: What does the 3 cubic meter model mean?
A: It refers to a nitrogen production capacity of 3 standard cubic meters per hour (3 Nm³/h), suitable for small to medium-sized welding stations or laboratory use.

Q: What is the required inlet pressure for the equipment?
A: We recommend an inlet pressure of 0.7~1.0 MPa. An oil-free air compressor and a refrigerated dryer are required to ensure gas quality.

Q: What is the outlet pressure of the nitrogen generator?
A: The outlet pressure can be adjusted within the range of 0.1~0.65MPa to easily adapt to different welding equipment.

Q: Is the equipment power-consuming?
A: The total power consumption of the machine is approximately 100~200W (excluding the air compressor), and the power consumption per cubic meter of nitrogen is approximately 0.42 kWh, which is very energy-efficient.

Q: How long does it take for the equipment to produce nitrogen?
A: It takes approximately 15~30 minutes after startup to produce qualified nitrogen. Once the purity is stable, it can be connected to the welding station. No prior experience is required for installation.
