The Aerospace Fuel Supply System from Neometrix Defence Limited is a fully integrated, skid-mounted installation for Aviation Turbine Fuel (ATF), Jet A-1, or kerosene service. Developed for engine test cells, APU facilities, and advanced combustion research centers, it integrates hydraulic, pneumatic, electrical, and automation disciplines to ensure flawless fuel management — from dual redundant pumps and dome-type regulators to aerospace-standard filtration and flow metering.

Six subsystems make up the skid: a Fuel Pumping Module that generates and maintains flow and pressure, an Emergency Supply Module providing nitrogen-pressurised backup, a Pressure Regulating Module for stable downstream pressure, a Fuel Metering Module for high-precision flow measurement, a Final Filtration Module for absolute fuel purity, and an Interconnection Network of stainless-steel piping and flexible hoses tying it all together. Each skid is fabricated from SS316/SS304, passivated for fuel compatibility, and equipped with drip trays, lifting lugs, and earthing points for operational safety and mobility.

Core Modules
