PhostrEx^TM fire suppression system.

Eclipse Aviation has developed the first new engine fire suppression system in 50 years, PhostrEx.  Used exclusively on the Eclipse 500™, PhostrEx is the only non-Halon engine fire suppression system approved by the Environmental Protection Agency and Federal Aviation Administration.  The result of these dual approvals is that PhostrEx is the only fire suppression system today that can meet the standards of the Montreal Protocol, an international treaty designed to protect the depletion of the earth’s ozone layer. Until now, aircraft were exempt from the treaty and allowed to use Halon.  That is, until a suitable replacement was available.  That replacement is the PhostrEx fire suppression system.

PhostrEx advantages.
The PhostrEx fire suppression system has been patented by Eclipse and is exclusive to the Eclipse 500.  PhostrEx is superior to Halon systems in all respects. 

• More effective – The PhostrEx agent is much more potent than Halon. Two teaspoons of the PhostrEx agent are equivalent to 2 1/2 cups of Halon.  And it is proven to actually extinguish fires.
• Lightweight – Because of the effectiveness of the PhostrEx agent, the total PhostrEx fire suppression system weight is approximately 90 percent less than a traditional Halon system.
• Low maintenance costs – The PhostrEx fire suppression system is much less complex than Halon systems and is designed to be maintenance free for 10 years.  After 10 years, you simply remove and replace the PhostrEx agent canister.  In contrast, most Halon systems require recurring maintenance every five years.  Overall lifecycle costs for the PhostrEx system are projected to be approximately one-tenth of a Halon system, contributing to the low direct operating costs of the Eclipse 500.
• Proven in extensive testing – Eclipse initiated a multi-million dollar development effort in 2003 to prove the efficacy of the PhostrEx agent by testing it in nearly 200 actual fires identical to those which might occur in aircraft engines.  A Fire Test Rig was designed and built to provide a platform to simulate engine-born fires.  Eclipse will be the only aircraft manufacturer to have an FAA-certified fire suppression system proven through actual fire testing.
• Environmentally friendly – The PhostrEx agent has no ozone-depletion potential and contributes nothing to global warming.  When the PhostrEx agent is released from its hermetically sealed canister, it works in less than one-tenth of a second, combining with moisture in the air and quickly becoming inert.  Because of this rapid reaction with moist air and surfaces, the agent cannot be transported to the stratosphere where ozone depletion could occur.  In a fire, the PhostrEx agent decomposes 1,000 times more rapidly than Halon and undergoes three sequential losses of bromine atoms, which are the power behind this agent.  These atoms catalyze suppression of the fire.
