Select a step where Air Liquide intervenes in your value chain.

Fuel tank inerting

Air Liquide is the leader in the field of aircraft fuel tank inerting via membrane based OBIGGS (On Board Inert Gas Generator System). OBIGGS systems prevent ignition of fuel tank vapors by providing inert gas generated on board the aircraft. The technology generates nitrogen enriched air to blanket the aircraft fuel tank and displace the flammable fuel/air mixture. Vulnerability to lightning, static discharge, or enemy fire for military aircraft, is greatly reduced by OBIGGS.
