Pre-Engineered FM200 Cabinet System with 10s Discharge Time and External Storage Piston Flow for 800㎡ Protection Area

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.

Main technical performance parameters of the system:

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.
