Key Features

  1. High Purity Output (99.99%)
    Guarantees contamination-free nitrogen, ensuring clean cuts and high-quality welding results.

  2. Concentration Meter with Flow Control

    • The flow meter allows precise control of nitrogen flow.

    • Reducing flow rate enhances nitrogen purity, ensuring consistency for critical applications.

  3. Programmable Time Relay

    • Controls the working sequence and pressure relief timing for Tower A and Tower B.

    • Pre-configured for optimal performance, requiring minimal user adjustment.

  4. PSA Technology for Stability
    Uses Pressure Swing Adsorption (PSA) technology to separate nitrogen efficiently, maintaining steady output.

  5. Monitoring Features

    • Air Pressure Gauge: Real-time monitoring of inlet pressure (0.6–0.8 MPA).

    • Nitrogen Pressure Gauge: Tracks nitrogen pressure in the storage tank.

    • Tower A and Tower B Pressure Gauges: Displays the operational status of carbon molecular sieve tanks, alternating between active and pressure-relief modes.

  6. Compact and Modular Design
    Designed for easy integration into industrial setups. Multiple units (3-4) can operate together to meet higher nitrogen demands.


Advantages of Using 3-4 Units

  1. Enhanced Nitrogen Supply
    Provides a combined flow rate of 9-12 NM³/h, suitable for large-scale laser cutting and welding projects.

  2. Redundancy for Continuous Operation
    If one unit undergoes maintenance, others can maintain the nitrogen supply.

  3. Scalability
    Easily expandable to meet increasing production requirements.

  4. Precise Nitrogen Purity Control
    Flow meter adjustments ensure nitrogen purity meets specific process requirements.

Applications

Industry Use Case
Laser Cutting Prevents oxidation for smooth, precise cutting of metals.
Welding Provides an inert environment for cleaner, stronger welds.
Electronics Ensures a contamination-free atmosphere for manufacturing components.
Pharmaceuticals Maintains sterility during production processes.
Food Packaging Increases product shelf life through nitrogen flushing.

Installation and Maintenance

  1. Air Inlet Preparation

    • Use a 16mm air pipe for the air inlet.

    • Ensure the air source is properly dehydrated and deoiled to protect the generator.

  2. Nitrogen Outlet Connection

    • Use a 12mm air pipe for the nitrogen outlet, connecting directly to the target system.

  3. Panel Monitoring

    • Regularly check pressure gauges for the air inlet, nitrogen tank, and towers.

    • Use the flow meter to adjust the nitrogen flow rate and concentration.

  4. Maintenance Tips

    • Periodically clean and inspect the air inlet to prevent blockages.

    • Follow recommended servicing schedules to ensure the long-term reliability of the PSA system.
