Product features


  • Wide flow range (3–1000 Nm³/h) – One platform covers small-scale lab use to large industrial plants.

  • High discharge pressure (up to 350 bar) – Enables direct cylinder filling and high-pressure process requirements without extra boosters.

  • Flexible compression stages (1–4) – Optimised for different inlet/outlet ratios, ensuring energy-efficient operation at any pressure.

  • Low speed (300–700 rpm) – Reduces mechanical wear, extends component life, and lowers noise levels.

  • Dual cooling options (air or water) – Adapts to site conditions, ambient temperature, and available utilities.

  • Moderate power consumption (≤55 kW) – Keeps operating costs low while delivering high output.

Customer Pain Points Solved


  • Inconsistent supply pressure – Our booster stabilises output even when inlet pressure fluctuates.

  • High energy bills – Multi-stage design and low speed minimise power consumption per Nm³ delivered.

  • Frequent downtime – Robust construction and low maintenance intervals reduce unplanned stops.

  • Space constraints – Compact footprint with flexible cooling choices fits tight installations.

  • Limited scalability – Wide flow range allows you to adjust capacity without replacing the entire unit.


Application Industries


  • Gas cylinder filling stations – High-pressure nitrogen for industrial, medical, and diving cylinders.

  • Oil & gas (EOR) – Nitrogen injection for well stimulation and pipeline purging.

  • Chemical & petrochemical – Inerting, blanketing, and reactor pressurisation.

  • Food & beverage – Modified atmosphere packaging and nitrogen flushing.

  • Electronics manufacturing – High-purity nitrogen for soldering and component storage.

  • Metal processing – Laser cutting, plasma cutting, and heat treatment.

  • Pharmaceuticals – Blanketing sensitive compounds and filling medical gas cylinders.

  • Automotive & tyre services – Nitrogen inflation for commercial and racing tyres.

Frequently Asked Questions (FAQ)


Q1: What is the recommended inlet pressure range?

A: The booster accepts suction pressure up to 25 bar; for lower pressures, we can adjust stages or add a pre-booster.


Q2: How do I choose between air-cooled and water-cooled?

A: Air-cooling is simpler and cost-effective for ambient <40°C. Water-cooling is preferred for high temperatures, continuous 24/7 operation, or where ventilation is limited.


Q3: How does speed affect performance?

A: Lower speed (300 rpm) reduces wear and noise; higher speed (700 rpm) increases flow. We set the optimal speed based on your flow and pressure requirements.


Q4: How many compression stages do I need?

A: Depends on inlet and outlet pressures. Typically, 1 stage for up to 10 bar difference, 2–4 stages for higher ratios. Our engineers will recommend the most efficient configuration.


Q5: What is the maintenance schedule?

A: Routine valve and filter checks every 2,000 operating hours; major overhaul at 8,000–10,000 hours.


Q6: Can this booster handle variable flow demand?

A: Yes, with optional variable speed drive or bypass control, it adapts to fluctuating downstream consumption.


Q7: Is the unit suitable for outdoor installation?

A: Yes, with appropriate weather-proof enclosure; otherwise, indoor installation is recommended.
