2NM³ Nitrogen Generator (ZHN-02) for Laser Cutting and Welding with 2-3 Units Configuration

The ZHN-02 Nitrogen Generator is specifically designed for industrial applications such as laser cutting and welding, delivering high-purity nitrogen (99.99%) with a controllable flow rate of 2NM³/h. Using 2-3 units of this generator provides enhanced nitrogen capacity, ensuring uninterrupted operation for demanding manufacturing environments.

ZHN-02


Product Specifications

Parameter Details
Model ZHN-02
Nitrogen Flow Rate 2 NM³/h (Controllable)
Nitrogen Purity 99.99%
Inlet Air Pressure 0.6–0.8 MPA
Nitrogen Output Pressure ≤0.6 MPA
Power Consumption 15 W
Supply Voltage AC220V
Dimensions (L×W×H) 500 × 450 × 780 mm

Key Features

  1. High Purity (99.99%)
    Ensures an oxidation-free environment critical for laser cutting and weld quality.

  2. Controllable Flow Rate
    Adjustable nitrogen flow rate of 2NM³/h provides flexibility to meet various production needs.

  3. Pressure Swing Adsorption (PSA) Technology
    Utilizes PSA to efficiently separate nitrogen from compressed air, ensuring stable and reliable output.

  4. Panel Monitoring Features

    • Air Pressure Gauge: Monitors the inlet air pressure (0.6–0.8 MPA) in real-time.

    • Nitrogen Pressure Gauge: Displays real-time pressure in the nitrogen storage tank.

    • Pressure Gauges for Tower A and Tower B: Allows monitoring of the carbon molecular sieve tanks’ pressures. Only one tower operates at a time, while the other is in pressure relief or regeneration mode.

  5. Compact and Modular Design
    Compact dimensions (500 × 450 × 780 mm) make it easy to integrate into existing setups. Deploying 2-3 units ensures scalability.


Advantages of Using 2-3 Units

  1. Enhanced Capacity
    Combining 2-3 units provides 4-6NM³/h nitrogen flow, sufficient for high-demand laser cutting and welding applications.

  2. Redundancy and Reliability
    Multi-unit setup ensures continuous operation even if one unit undergoes maintenance.

  3. Optimized Energy Usage
    Low power consumption of 15W per unit ensures cost-effective operation for multiple units.

  4. Flexible Configuration
    Units can be used individually or together based on production needs, offering operational flexibility.

Applications

Industry Use Case
Laser Cutting Prevents oxidation and ensures clean, smooth cuts.
Welding Protects welds from contamination for enhanced quality.
Electronics Provides an inert atmosphere for precise assembly.
Pharmaceuticals Creates a sterile environment for drug production.
Food Packaging Preserves freshness with nitrogen flushing systems.

Installation and Maintenance

  1. Air Inlet Requirements

    • Use clean, dry compressed air at 0.6–0.8 MPA pressure.

    • Connect using the designated air inlet port with an appropriate pipe.

  2. Nitrogen Outlet Connection

    • Use the nitrogen outlet port for direct integration with the laser cutting or welding system.

  3. Monitoring and Adjustments

    • Check the air pressure gauge regularly to ensure proper inlet pressure.

    • Monitor the pressure gauges for Tower A and Tower B to verify operational status.
