FM-200
gas is manufactured by M/s. Great Lakes Chemical Corporation
(GLCC) and is the new solution to replace Halon 1301 in fire
protection applications. FM - 200 (CF3CHFCF3 – HEPTAFLOUROPROPANE)
is a clean, efficient, environmentally acceptable, and leaves
no residue, thus minimizing any downtime after a fire. It
has a Ozone Depletion Potential (ODP = 0) many applications
require clean extinguishants for use on active electrical
systems or Class C fires. FM-200 has been shown to be electrically
non-conductive and is safe for electrically charged e quipment.
It is colourless, odourless and suppresses fire by interrupting
the combustion process and affecting the available oxygen
content in the area of the discharge .
FM-200
provides protection equal to that of Halon 1301. It rapidly
extinguishes fires through a combination of chemical and physical
mechanisms. The minimum design concentration of FM-200 is
7% by volume, compared to 5% for Halon 1301. This means that
only 70% more agent by weight is required as compared to a
typical Halon 1301 system, additional storage space requirements
are minimal. There is no need to clutter a facility with bulky
racks of heavy, high-pressure cylinders such as those used
in inert gas systems.
The
fixed FM-200 (HFC-227ea) extinguishing system is designed,
installed and commissioned in accordance with the latest version
of National Fire Protection Association Standard NFPA 2001,
(standard on Clean Agent Fire Extinguishing Systems)
FM-200
is stored as liquid in seamless steel containers and superpressurised
with nitrogen to 360 / 600 psig (25/42 Bar) to increase its
discharge flow characteristics.
Worldwide
supply of FM-200 gas by M/s. Great
Lake Chemical Corporation for Fire Extinguishing
application is through six authorised OEM suppliers. Siemens,
Cerberus Division is one of them.
Unlike
other manufacturer, Cerberus
offers High Pressure (42 Bar) FM-200
system. It offers better performance due to high
pressure technology. It ensures that FM-200 storage pressure
is 42 bar and minimum operating pressure at the nozzle is
10 bar.
