Hygood FM-200 Gas Suppression System

FM-200 works by removing the element of heat from a fire to interrupt combustion and suppress a fire. It is non-conductive so there is no effect on energized electrical components upon discharge, and with zero ozone depleting potential, it has proved to be the most widely selected replacement for Halon 1301.



HYGOOD FM-200 systems are accepted as providing reliable and effective fire protection solutions for high value assets, processes and locations, as well as the people who work in these protected areas.

The FM-200 Clean Agent is a colorless, odorless, non-contaminating gaseous fire protection agent. Electrically non-conductive, FM-200 works by removing heat from a fire so that combustion cannot be sustained. The decision to use FM-200 can be based on a number of key factors: it is the most widely used of the chemical replacements for Halon 1301 and it is an agent that has been used to successfully protect tens of thousands of high-technology facilities in 70 countries around the world.

Extensively tested, FM-200 systems are proven safe for use in occupied areas. They are designed using bespoke software, which accurately calculates the amount of FM-200 required for the protected space. The target concentration of FM-200 in an identified protected volume is matched to international standards, which themselves are the result of extensive and repeated fire tests, to match design to fire protection performance.
