Industrial Nitrogen Generators for Laser Welding
ZHN-L Series Laser Welding Nitrogen Generators
ZHN-03L 60NL/min High Purity Nitrogen Making Machine for Laser Welding Machines
Overview
The ZHN-03L Nitrogen Making Machine is a high-capacity, high-purity nitrogen generator engineered for modern laser welding applications. Delivering 60 NL/min of nitrogen gas with a purity adjustable between 95% and 99.999%, it ensures a continuous, on-demand, and cost-effective supply of nitrogen directly at your facility.
This industrial-grade nitrogen generator eliminates the need for costly bottled nitrogen deliveries, reduces downtime, and provides a stable gas supply for optimal welding quality. With intelligent PLC control, integrated air drying and filtration systems, and a user-friendly interface, the ZHN-03L is designed to meet the rigorous demands of manufacturing workshops, metal fabrication plants, and large-scale production lines.
Key Features & Advantages
1. High Capacity for Industrial Production
With an output of 60NL/min, the ZHN-03L is ideal for high-volume welding operations, including robotic welding cells and multi-machine setups.
Supports multiple welding stations simultaneously
Maintains stable nitrogen flow under heavy-duty usage
Reduces operational interruptions caused by gas shortages
2. Adjustable High Purity (95% – 99.999%)
Different welding materials and applications require different nitrogen purity levels. The ZHN-03L offers flexible purity settings to match your needs:
95%-98% for general welding where cost efficiency is prioritized
99%-99.999% for critical welding jobs that demand maximum protection against oxidation and discoloration
3. PLC Intelligent Control System
An advanced Programmable Logic Controller (PLC) ensures fully automated, stable, and energy-efficient operation:
Monitors flow rate, purity, and pressure in real-time
Automatically adjusts system performance to match demand
Provides alarm notifications for maintenance and fault conditions
Saves energy by optimizing compressor and filtration cycles
4. Integrated Refrigerated Air Dryer
Moisture in compressed air can degrade nitrogen purity and damage welding quality. The ZHN-03L integrates a high-performance refrigerated air dryer to:
Remove moisture before gas separation
Prevent oxidation and contamination during welding
Prolong the life of filters and separation modules
5. Triple Filtration System for Ultra-Clean Gas
The ZHN-03L uses a three-stage filtration process to guarantee ultra-pure nitrogen:
Primary Filter: Removes large particles, dust, and water droplets
Fine Filter: Captures micro-particles and oil aerosols
High-Efficiency Filter: Ensures the nitrogen meets high-purity standards for sensitive welding applications
6. Automatic Condensate Drainage
An automatic drainage system discharges accumulated moisture without manual intervention, reducing maintenance time and keeping the system in optimal condition.
7. Direct Air Compressor Integration
Designed for easy installation, the ZHN-03L connects directly to your existing air compressor for immediate nitrogen production—no external storage tanks required.
8. 7-Inch Multilingual Touchscreen
The user-friendly touchscreen provides:
Real-time operational data
Easy access to system settings
Multi-language interface for global use
Step-by-step troubleshooting guidance
