Pre-Engineered External Storage FM200 System
Description:
The FM200 external storage piston flow fire suppression system is a
high-reliability clean agent fire protection solution using
HFC-227ea (FM200) as the extinguishing agent. By adopting an
externally driven pressure design, the system provides additional
propulsion to deliver the agent over long distances, making it
ideal for large spaces and complex piped network layouts.
With a maximum working pressure of 8MPa, a driving cylinder
pressure of 6.0MPa (20℃), and a pressurizing cylinder pressure of
13.5MPa, the system ensures fast and stable discharge. The
discharge time is ≤10 seconds, enabling rapid fire suppression at
the early stage of a fire. Cylinder volumes range from 90L to 245L,
with filling capacities from 112.5kg to 306.25kg. A single zone can
protect up to 800㎡ in area or 3600m³ in volume, offering flexible
configuration for different project requirements.
FM200 (HFC-227ea) is a colorless, odorless, low-toxicity,
non-conductive and residue-free clean agent. It causes no damage to
sensitive equipment and requires no post-discharge cleanup,
ensuring business continuity and asset protection.
The system supports both automatic and manual activation modes,
providing high operational reliability and easy maintenance. It is
widely used in data centers, server rooms, telecom rooms, power
distribution rooms, control rooms, libraries, archives, vaults and
underground facilities, and is suitable for Class A, B, C fires as
well as electrical fires.
Compared with conventional piped FM200 systems, the external
storage piston flow design significantly improves discharge
distance and agent distribution uniformity, effectively solving
problems such as pressure loss in long pipelines and insufficient
discharge in large spaces. It is an ideal fire suppression solution
for critical assets and large-scale fire protection projects.

Fire extinguishing principle of fire extinguishing agent:
HFC-227ea fire extinguishing agent extinguishes fire mainly due to
its fast heat removal speed. Its fire extinguishing principle is
composed of the following three parts:
1) cooling the protected area; 2) dispersion of fire extinguishing
agent; 3) consumption of oxygen.
(1) HFC-227ea fire extinguishing agent is sprayed into the
protected area in liquid form. When spraying out of the nozzle, the
liquid fire extinguishing agent can quickly turn into gas and
absorb the heat of the master. It reduces the temperature of the
protected area and the surrounding of the flame.
(2) HFC-227ea fire extinguishing agent is composed of large
molecules. When extinguishing a fire, some of the bonds in the
molecules are broken and heat is absorbed.
(3) The spraying of fire extinguishing agent and the presence of
flame in the protected area reduce the concentration of oxygen,
thereby reducing the combustion rate.
Working principle of independent unit system
The working principle of this system is relatively simple. Only
when a fire occurs, the alarm control panel issues a command. After
a delay, the solenoid valve opens and releases the nitrogen in the
driving gas bottle group. The starting gas passes through the
starting pipeline, opens the power drive bottle group to work, and
the gas in the power drive bottle group pushes the fire
extinguishing agent in the fire extinguishing agent storage bottle.
The fire extinguishing agent passes through the connecting hose and
the liquid flow one-way valve into the collecting pipe, the
delivery pipe network, and the nozzle to spray the fire
extinguishing agent into the protected area to put out the fire.

Applications:
It is widely used in computer rooms, power distribution rooms,
telecommunications centers, libraries, archives, treasure chest and
underground engineering for the class A, B, C fire and electrical
equipment fire. But it is not applicable to potassium, sodium,
magnesium, uranium and active metal chloride and digestive fiber
fire places.
