Unlike conventional nitrogen trolleys that rely on pre-filled bottles, the U-SGNSC generates high-purity nitrogen gas (>99.5%) on demand, ensuring autonomy and reducing logistical dependency. It is deployed in flight-line environments for on-ground maintenance, servicing and mission readiness of aircraft and helicopters. Its diesel-powered, trailer-mounted design makes it rugged, mobile and suitable for forward operating bases, where reliability and independence are crucial.

The system integrates advanced gas generation, compression and storage subsystems into a modular towable trailer unit, enclosed within an equipment protective canopy painted in standard military olive green, providing weather protection, acoustic damping and easy maintenance access.

No bottles. No resupply convoy. Nitrogen on demand, on site.

Designed as per IAF RFP requirements with qualification test procedures (QTP) and acceptance test procedures (ATP) approved by RCMA/CEMILAC, the cart aligns with the Indian Air Force indigenisation drive — fully developed and manufactured in India.

Plain-language answers from the engineering team.

Q · 01 What is the Universal Self-Generating Nitrogen Service Cart (U-SGNSC)?

The Universal Self-Generating Nitrogen Service Cart (U-SGNSC, Model A4029) is a rugged, towable ground support system built by Neometrix Engineering Pvt Ltd, India. It generates greater than 99.5% pure nitrogen on demand from a diesel-driven compressor and membrane separation train, and delivers it at up to 303 bar (4400 psi) for aircraft tyre inflation, landing gear strut servicing and hydraulic accumulator charging.

Q · 02 Who manufactures the U-SGNSC nitrogen service cart?

The Universal Self-Generating Nitrogen Service Cart is designed and manufactured by Neometrix Engineering Pvt Ltd, a leading ground support equipment manufacturer and supplier based in India, for the Indian Air Force and export defence customers.

Q · 03 Why does the cart generate its own nitrogen instead of using bottles?

Conventional nitrogen trolleys depend on pre-filled cylinders and recurring resupply logistics. The U-SGNSC integrates its own diesel-driven compressor, dryer and dual Parker SmartFluxx SA1508 membrane skid, so it produces greater than 99.5% pure nitrogen on-site and on demand, eliminating dependency on bottled gas at forward operating locations.

Q · 04 What pressure and purity does the U-SGNSC deliver?

The system delivers nitrogen at a minimum purity of 99.5%, boosted by a hydraulic intensifier to a maximum delivery pressure of 303 bar (4400 psi) at 18 Nm3/hr, with two ISO 9809-2 certified cylinders providing approximately 850 ft3 of stored nitrogen at STP.

Q · 05 What powers the Universal Self-Generating Nitrogen Service Cart?

An 80 HP, BS-VI compliant diesel engine (Ashok Leyland P15) with CRDI fuel injection drives a 75 CFM, 12 bar feed-air compressor and the hydraulic intensifier, making the cart fully self-contained and independent of external power or gas supply.

Q · 06 What applications is the U-SGNSC used for?

The cart is used for aircraft tyre inflation, landing gear strut servicing, hydraulic accumulator charging, on-ground engine start support, general flight-line maintenance, and remote operations at forward operating bases where bottled nitrogen is impractical.

Q · 07 Does the U-SGNSC comply with relevant standards?

Yes. The high-pressure storage cylinders are ISO 9809-2 certified, and the system is designed as per IAF RFP requirements with prototype trials, qualification test procedures (QTP) and acceptance test procedures (ATP) approved by RCMA/CEMILAC, within an AS9100/ISO 9001/DGAQA-aligned quality framework.

Q · 08 How is nitrogen purity monitored during operation?

A PLC-based operator panel with a digital nitrogen purity analyzer (Honeywell A02) provides continuous, real-time purity monitoring, alongside safety alarms, gauges and protective interlocks including oxygen sensing and auto-shutdown.
