Engine Bleed Air System

Engine bleed air systems bleed high pressure, high temperature air from the engine's low pressure and high pressure ports. The air flow is processed through temperature and pressure control devices and supplied downstream to the aircraft's main air conditioning system, to the airframe anti-icing system and to the main engine starting system.

An engine bleed air system consists of temperature control valves, pressure regulating valves, high pressure valves, pre-coolers heat exchangers, high pressure ducting, temperature sensors, pressure sensors, overheat / hot air leak detection devices and a control and monitoring electronic unit.

Liebherr supplies all components required for this type of systems and equips all kind of aircraft that need such function, like commercial airplanes, regional aircraft, military transport aircraft, fighters or business jets.
