Fire suppression systems
World-beating components, intelligently
Meggitt offers a complete fire protection system using the
best components in the world.
Our knowledge and experience is gained from 40 years of installing
suppression systems on virtually every aircraft flying.
As a result, we are able to keep weight and size to a minimum,
reducing the initial cost to OEMs and the operational cost
Unique flow-metering capability
With aircraft range increasing over the last decade, we provide
airframers with suppression systems they can rely on for longer
diversions in the event of a cargo fire.
Our low-rate systems are fitted with a unique flow-metering
design enabling slow and accurate release of the suppression
agent. When fire occurs during flight, the system maintains
the exact level of extinguishing agent in cargo compartments.
Less accurate systems require more agent, increasing overall
Pioneering environmentally-friendly suppression
As the industry moves away from Halon, we continue to pioneer
new solutions. With large investments in our research team
and facilities, we are exploring usage and delivery of new
and more sustainable suppression agents designed for extremes
of temperature and altitude.
• Reduced costs: superior components and system engineering
reduce weight and space demands, resulting in lower OEM and
• Enhanced reliability: 40-year track record of in-house
design and manufacture; complete suppression systems installed
on virtually every aircraft flying
• Ultimate optimization: thanks to extensive certification
experience of Halon and green agent systems, we can help you
fine-tune performance, weight and envelope
How it works
Our fire protection systems are designed for immediate fire
suppression and long-term sustained protection during flight
The high-rate, multi-shot extinguishing bottles put out fires
(engine, APU and cargo) within seconds using directional valves
and distribution tubing solutions for total flooding.
The low-rate bottles use a unique metering design that allows
flow of the suppression agent, whether in gas or liquid state,
to be metered across a wide range of temperatures.
Aircraft fire protection reliability and safety is improved
by our patented temperature-compensated pressure switch which
determines whether the fire extinguisher is fully charged,
regardless of ambient temperature.
Bottles can be sized anywhere from 10 to 2,500 in3 (164 cm3
– 0.04m3 ) and can be made from steel or titanium, depending
on weight requirements.
• Proprietary design: unique flow metering equipment
measures over wider range of temperatures
• Industry-leading certification support
• Pioneering research into usage and delivery of environmentally-friendly
