Why Hawkstein Nitrogen Technology

Dynamic Pressure Versatility: Aerospace nitrogen requirements vary. Our units handle standard tire inflation (approx. 200 PSI) and high-pressure landing gear strut charging (up to 4000+ PSI) using specialized regulators & Boosting system
Proactive Contamination Control: Modern pneumatic systems (tires/struts) are sensitive. We use inline particulate filters and specialized dry nitrogen (Dew point <-60°C) to prevent internal system corrosion.
Tarmac-Proven Engineering: Our heavy-duty chassis and all-terrain wheels allow safe, stable towing across taxiways and field environments, ensuring the gas is delivered exactly where it’s needed.

FAQs

It is primarily used for the safe, dry, high-pressure charging of aircraft tires, landing gear struts, and hydraulic accumulators. Nitrogen prevents tire blowout and maintains hydraulic system stability.

Standard air contains moisture and oxygen, which causes internal tire degradation and can freeze/cause corrosion in landing gear. Dry Nitrogen is an inert gas that eliminates these critical risks.

Aviation (Commercial & Military), Ground Support Equipment (GSE) providers, MRO facilities, and specialized high-pressure test environments.

Yes. For applications requiring pressure up to 415 Bar (6000 PSI), we integrate an optional air-driven Nitrogen Pressure Booster, enabling efficient high-pressure charging from standard cylinders.

Strategic Applications

The Hawkstein Nitrogen Service Unit is a mission-critical asset across diverse high-precision industries.

Aviation & MRO (Maintenance)

Tire Inflation: Ensuring safe, precise, high-volume charging for commercial and military aircraft wheels.
Strut Charging: High-pressure replenishing of nose and main landing gear oleo struts.

Aerospace & Defense Support

Ground Support Systems: Pressurizing naval missile launch accumulators and naval steering gear systems.
Accumulator Maintenance: High-pressure charging of flight control hydraulic accumulators.

Industrial & Power Generation

High-Pressure Test Loops: Providing a controlled Nitrogen source for pressure testing pipelines and valves.
Sealing Gas Systems: Supplying back-up gas for high-speed industrial turbine seals.

Why Specialized Nitrogen Support is Non-Negotiable

Mission Safety: Tarmac operations demand safety. Nitrogen avoids the flammable risks of compressed air for tire servicing and prevents internal component ignition.
System Life Extension: By eliminating moisture and contaminants, our NSU prevents internal corrosion of high-value landing gear, potentially doubling the component life.
Operational Readiness: Engineered for rapid towing (up to 15 MPH on flat tarmac), the unit ensures your support crew can service multiple aircraft without unnecessary delays, reducing critical turnaround times.
