Halotron BRX

Halotron BrX™ (2-BTP) Amerex provides a unique solution for Halon 1211 replacement. These extinguishers utilize Halotron BrX to fulfill the next generation of aviation extinguisher requirements. BrX is a low GWP and very low ODP clean agent approved for use on commercial aircraft. The extinguishers are constructed of a lightweight aluminum valve assembly and cylinders (Model 351 has a steel cylinder). Models 349 and 351 include a hose that allows the operator greater flexibility for utilization in tight spaces.

Halotron BrX (stabilized 2-BTP) is a high-performance clean extinguishing agent (i.e., volatile and electrically non-conductive) designed for applications where efficient firefighting performance is the most crucial factor.

The unique molecule employed contains bromine, which is “chemically active” (i.e., a chain breaker atom which interferes with the chemical transitions necessary to support combustion). It, therefore, offers an advantage over conventional clean agents. These other common clean agents, including hydrofluorocarbons (HFCs) and fluoroketones, extinguish fires primarily utilizing a physical action (heat removal) effect.

This property of Halotron BrX enables a lower weight equivalence to halon 1211 compared to other halocarbon clean agents that do not have the chain-breaking effect and require more extensive and heavier extinguishers. This weight effectiveness has resulted in Halotron BrX gaining acceptance as an adequate replacement for halon in aviation uses.

In addition, since it is a clean agent, it does not leave potentially harmful residues after application. This is in contrast to conventional dry chemical agents such as mono-ammonium phosphate (MAP) (“ABC Dry Chemical”) and potassium bicarbonate (“Purple K”) which both leave fine particle dust that has to be cleaned up and that can be corrosive.
