ZHN-01L
(Models: ZHN-01L / ZHN-02L / ZHN-03L)
The ZHN-L Series Laser Welding Nitrogen Generators are advanced, high-performance gas generation systems designed to meet the demanding needs of modern laser welding operations. Engineered with precision and manufactured to the highest quality standards, these machines deliver a reliable and continuous supply of high-purity nitrogen gas directly on-site.
By eliminating the dependency on bottled nitrogen, the ZHN-L series significantly reduces operational costs, simplifies logistics, and improves overall welding efficiency. With cutting-edge control systems, integrated purification technology, and a compact, user-friendly design, these nitrogen generators are the ideal solution for manufacturers, workshops, and industrial facilities seeking superior welding performance and productivity.
Each ZHN-L nitrogen generator is equipped with a modern Programmable Logic Controller (PLC), ensuring intelligent, stable, and automated operation.
Continuous monitoring of system parameters
Automatic fault detection and alarm functions
Easy control via the touch interface
Optimized nitrogen generation for efficiency and performance
This intelligent control ensures that the nitrogen purity and flow remain consistent during the entire welding process, guaranteeing repeatable, high-quality results.
Moisture in compressed air can negatively affect both the nitrogen purity and the welding quality. The ZHN-L series integrates a high-efficiency refrigerated air dryer, which:
Removes moisture from the incoming compressed air
Prevents oxidation and contamination
Extends the service life of filters and nitrogen separation modules
This built-in feature ensures that the nitrogen supply is always dry, clean, and stable.
For applications that demand extremely pure nitrogen (up to 99.999%), the ZHN-L nitrogen generators include a three-stage filtration process:
Pre-filter: Removes large particles and oil mist
Fine filter: Eliminates small particulate matter and residual oil
High-efficiency filter: Ensures ultra-clean, high-purity nitrogen output
The triple filtration not only improves gas quality but also protects downstream equipment and laser welding heads from damage.
The system features automatic condensate drainage, minimizing maintenance needs and preventing moisture buildup.
This reduces downtime, lowers labor costs, and maintains consistent nitrogen purity over extended periods.
The ZHN-L series is designed to integrate seamlessly into existing workshop setups. It can be connected directly to an air compressor, with the gas ready for immediate use.
No additional storage tanks or complicated pipelines are necessary, making installation fast and cost-effective.
User interaction is made simple with a 7-inch industrial-grade touchscreen, supporting multiple languages for global operation.
Clear display of operating status
Easy adjustment of parameters
Quick troubleshooting guidance
Suitable for operators of different skill levels
Nitrogen plays a crucial role in laser welding by preventing oxidation, improving bead appearance, and reducing porosity in weld joints. The ZHN-L series provides:
Stable Gas Flow – Essential for consistent welding results
High Purity – Reduces discoloration and oxidation of metals
Versatility – Suitable for welding stainless steel, aluminum alloys, titanium, and more
These generators are ideal for use with:
Fiber laser welding machines
Handheld laser welders
CNC laser welding systems
Robotic welding lines
