Aircraft Hanger High Purity Nitrogen Generation Servicing System

The Aircraft Hangar High Purity Nitrogen Generation Servicing System, specifically the High Purity Self-Generating Nitrogen Service Cart (HP-SGNSC), is a state-of-the-art, self-contained unit designed to produce and supply high-purity nitrogen gas for various aircraft maintenance applications. Manufactured by Hydraulics International, Inc. (HII), this system ensures a reliable and on-demand source of nitrogen, eliminating the logistical challenges associated with traditional nitrogen supply methods.​

Technical Details:

1. Nitrogen Production:

   • Purity: The system generates nitrogen gas with a purity level of 99.5% or higher, suitable for sensitive aircraft systems.​

   • Flow Rate: Capable of producing nitrogen at a flow rate of 30 Standard Cubic Feet per Minute (SCFM), supporting rapid servicing operations.​

2. Pressure Capabilities:

   • High-Pressure Output: Delivers nitrogen at controlled pressures ranging from 0 to 5,000 Pounds per Square Inch Gauge (PSIG), ideal for servicing high-pressure aircraft systems and components.​

   • Low-Pressure Output: Provides nitrogen at controlled pressures between 0 and 400 PSIG, suitable for applications such as tire inflation and servicing other low-pressure components.​

3. Design and Mobility:

   • Configuration: The system is enclosed, skid-mounted, and electric-driven, ensuring durability and ease of integration within hangar facilities.​

   • Portability: Designed for mobility within the hangar environment, facilitating convenient access to various aircraft and maintenance areas.​

4. Automation and Control:

   • PLC Controlled: Features an automated Programmable Logic Controller (PLC) system that manages nitrogen generation and filling processes, minimizing the need for manual intervention.​

   • Human-Machine Interface (HMI): Equipped with a touch-screen interface providing full operation and maintenance diagnostics, including fault logs and troubleshooting aids.​

5. Compressor Technology:

   • Oil-Less Compressors: Utilizes 100% oil-less feed and high-pressure air compressors, eliminating the need for oil separators. This design choice extends the lifespan of nitrogen separation membranes and reduces overall maintenance costs.

6. Efficiency:

   • Rapid Filling: Capable of filling on-board storage bottles to 5,000 PSIG with 99.5% pure nitrogen in less than 45 minutes at ambient temperature, ensuring quick turnaround times

Applications:

• High-Pressure System Servicing: Suitable for charging aircraft high-pressure nitrogen systems and components, such as accumulators and struts.​

• Tire Inflation: Provides a reliable source of nitrogen for inflating aircraft tires, enhancing safety and performance.​

• Maintenance Support: Supports various maintenance activities within the hangar by supplying high-purity nitrogen on-demand, improving operational efficiency.​
