Fuel Tank Inerting Systems

Honeywell’s fuel tank inerting systems are installed in various commercial airliners worldwide. Engineering the first certified fuel tank inerting system for commercial airliners, Honeywell has a long legacy of delivering innovative safety systems to aviation. For over a decade, Honeywell has led the integration of Nitrogen Generation Systems (NGS) into large air transport applications. 

The on-board inert gas generation system (OBIGGS) is the industry's first FAA-certified commercial air transport system to utilize nitrogen enriched air to reduce explosion risk.

The slideshow displays customizations that were built with Honeywell’s fuel inerting systems.

What is a Fuel Tank Inerting System?

An inerting system uses advanced technology to reduce the amount of oxygen that enters a fuel tank in order to reduce risks of combustion.

What is a Nitrogen Generation System (NGS)?

Honeyewll’s nitrogen generating systems (NGS) generate nitrogen enriched air to fuel tanks. The NGS requires no flight or ground crew action for normal system operation and is not dispatch critical.
