Nitrogen Booster

Designed specifically for nitrogen pressure boosting, this device efficiently compresses low-pressure nitrogen (5–10 bar) to high-pressure levels—up to 300 bar or beyond—serving the demanding needs of industrial, scientific, and specialized applications.

Performance Highlights

  • Pressure Range: Stable boosting from 100 to 300 bar, with custom options available for higher pressures.

  • Purity Assurance: Oil-free design maintains nitrogen purity at 99.9%–99.999%, eliminating contamination risks.

  • Energy Efficiency: Achieves 30–50% energy savings relative to liquid nitrogen vaporization methods.

  • Control System: Integrated PLC or touchscreen interface for accurate pressure management and automatic voltage stabilization.

  • Safety Features: Built-in overpressure protection, overload cutoff, and leak detection for secure operation.

Industry Application

  • Industrial Manufacturing
    Widely used in laser cutting, tire nitrogen filling, and metal heat treatment as shielding gas to improve product quality and process stability.

  • Energy & Power
    Provides reliable nitrogen sealing for transformers and pressurization for energy storage systems, ensuring safe and stable operation.

  • Laboratory & Research
    Serves as carrier gas for chromatography and enables precise environmental control in material testing applications.

  • Aerospace
    Supports fuel system testing and supplies high-pressure nitrogen for airborne equipment, meeting stringent safety and performance standards.

  • Petrochemical
    Ideal for pipeline pressure testing and reactor inert gas protection, enhancing safety during critical operations.

Q & A Collection

  • Q1: What is the boost pressure?

       A: Standard models are 100-300 bar, and custom models can reach over 500 bar.

  • Q2: Does it require an external gas source?

       A: It requires connection to a nitrogen cylinder/generator (inlet pressure ≥ 5 bar).

  • Q3: How is nitrogen purity guaranteed?

      A: It uses stainless steel piping and precision filtration, with an optional purity analyzer.

  • Q4: What is the flow rate range?

      A: 0.5-20 Nm³/h (multiple units can be connected in parallel to increase flow).

  • Q5: Is maintenance complex?

      A: Routine inspection for leaks and replacement of consumables every 2,000 hours are all that's required.
