FM 200 SYSTEM

23 of 26

FM 200 SYSTEM

  • FM-200 Removes Heat Energy Not Oxygen
  • Effective on Class A, B, and C fires, FM-200 extinguishes fires quickly through a combination of chemical interaction and physical heat removaL It does not smother flames by removing oxygen. FM-200 removes heat energy from fire, not oxygen from the environment. FM-200 absorbs heat from the flame zone and interrupts the chemical chain
  • reaction of the combustion process.

FM 200 SYSTEM

25 of 26

FM 200 SYSTEM

​

  • Storing FM-200 in cylinders as a liquid saves substantial storage space.

​

  • In addition, most FM-200 systems require less than 7% concentration to quickly extinguish a fire.
