Core Product Advantages

I. High Purity Performance, Precisely Optimized for Welding Processes

The standard configuration delivers stable 99.99% high-purity nitrogen, with customizable ultra-high purity up to 99.999% for precision welding scenarios. High-purity nitrogen effectively isolates the welding zone from ambient oxygen, fundamentally preventing weld oxidation, surface discoloration, and internal porosity. It produces smooth, bright, and uniform weld sections, greatly reducing post-weld grinding, rework, and defective rates, and significantly improving final product yield.

This nitrogen generator adapts perfectly to the welding of stainless steel, aluminum, copper, and various alloy materials, delivering consistent and reliable welding quality for diverse processing demands.

II. Complete Specification Range, Supporting Standard and Custom Solutions

Our product lineup covers all mainstream flow rates from 1 Nm³/h to 20 Nm³/h, including 1, 3, 4, 5, 8, 10, 15 and 20 Nm³/h models. It can accurately match both single small welding stations and centralized gas supply systems for multiple workshop workstations.

All core parameters including nitrogen flow rate, outlet pressure, purity grade, and overall equipment dimensions support full personalized customization according to actual workshop layout and production requirements. Customers can achieve fully on-demand configuration without capacity waste, avoiding compromises caused by fixed standard models.

III. Mature PSA Nitrogen Generation Technology, Fast Output and Stable Purity

Adopting ambient-temperature Pressure Swing Adsorption (PSA) technology, the equipment applies a dual-tower alternating adsorption and regeneration system, equipped with high-quality imported carbon molecular sieves. Qualified standard-purity nitrogen can be steadily produced within 20 minutes after startup.

Supported by intelligent PLC automatic control, the machine maintains constant pressure, stable purity, and continuous flow output during long-term operation without performance attenuation. It supports 24-hour uninterrupted cyclic operation to fully meet continuous industrial welding production needs.

IV. Integrated Skid-Mounted Structure, Small Footprint and Easy Installation

The whole machine adopts an integrated skid-mounted compact design with a neat and reasonable internal layout, minimizing workshop space occupation. It requires no customized concrete foundation construction or complex pipeline layout.

After placing the unit on a flat ground and connecting power and compressed air sources, the equipment can realize fully automatic on-site nitrogen production. The operation process is simple and intuitive, requiring no professional technicians for installation, commissioning, or daily operation, effectively saving labor and engineering costs.

V. On-Site Self-Gas Supply, Highly Cost-Effective Replacement for Liquid Nitrogen

The system takes atmospheric air as the raw material and only consumes electric power during operation, completely eliminating the recurring cost of purchasing bottled nitrogen or liquid nitrogen. As a one-time investment for long-term self-sufficient gas supply, it greatly reduces enterprises’ daily gas consumption expenditure.

With durable carbon molecular sieves, low failure rate, and simple daily maintenance, the equipment investment can generally be recovered within 1 to 2 years. It is the most economical and reliable long-term nitrogen supply solution for welding factories and precision processing workshops.

FAQ

Q: What standard nitrogen purity is required for welding processes?

A: 99.99% purity meets the demands of regular welding work. For precision electronic component and lithium battery welding, we provide customizable ultra-high purity up to 99.999%, which thoroughly avoids weld oxidation and pore defects.

Q: What standard flow rate models do you have in stock?

A: Our ready-to-ship specifications cover 1, 3, 4, 5, 8, 10, 15 and 20 Nm³/h. Customized flow rates, working pressures and nitrogen purity grades are all available for special production demands.

Q: Can one nitrogen generator supply gas for multiple welding machines simultaneously?

A: Yes. Calculate the peak total gas consumption of all welding equipment working at the same time and add a 20% safety allowance (1.2 times the calculated flow). One single unit can realize centralized gas supply for multiple workstations, cutting equipment investment and saving workshop space.

Q: How much time does it take to reach target nitrogen purity after startup?

A: The equipment can output nitrogen that meets standard purity requirements in roughly 20 minutes after startup. It then runs fully automatically around the clock with steady pressure and consistent nitrogen purity.

Q: Does an on-site nitrogen generator save more cost compared to buying bottled or liquid nitrogen?

A: An in-house nitrogen generator removes repeated expenditure on purchased nitrogen gas, greatly lowering long-term production gas costs. Under regular continuous production, the equipment investment can be fully recovered within 1 to 2 years.

Q: Is the installation procedure complicated?

A: Not at all. No dedicated concrete foundation or complex pipeline construction is needed. Just place the unit on flat ground and connect the power supply, and the machine is ready for operation. Installation is extremely simple and can be completed by staff without professional technical background.
