Inert Gas

Description

Chemori Inert Gas Fire Extinguishing System consists of high pressure cylinders filled with either IG-55, IG-100 or IG-541 agent under pressure, connected to fixed piping and nozzles or hoses which is designed in accordance to the National Fire Protection Association (NFPA) 2001: Standard on Clean Agent Fire Extinguishing System and EN 15004: Fire Fighting System.

Seamless steel cylinders manufactured in accordance with the following specifications.

  • Pressurized equipment directive 97/23/CE (CE Marking)
  • Transportable pressurized equipment directive (TPED) 199/36/CE (CE Marking)

 

Cylinders used for the inert gas system have the design pressure of 2,900 psi (200 bar) and 4,351 psi (300 bar) with the test pressure of 6,526 psi (450 bar). Each cylinder is equipped with valve containing a safety burst disc for protection against over pressurization due to elevated temperature.

Chemori IG-541 is composed of 40% Argon, 52% Nitrogen and 8% of CO2. Chemori IG-541 suppression systems are based on the principle of reducing the oxygen concentration inside the protected hazard. The oxygen concentration is minimized by the application of IG-541 until it reaches a level where combustion is no longer supported. Each system is designed so as to decrease oxygen to a specific level. When discharged, Chemori IG-541 is quickly and uniformly distributed within the enclosure, achieving design concentration in 60 seconds.

Chemori IG-100 is made up of 100% of Nitrogen. This inert gas is naturally present in the atmosphere, therefore, its greenhouse effect is nil and its ozone layer depletion potential is zero. It is chemically inert, non-conductive, colorless, odorless and flavorless. Chemori IG-100 is non-corrosive and may be used at normal temperatures with such materials as nickel, steel, stainless steel, copper, brass, bronze and plastics.

This is a blend of 50% Argon & 50% Blend of Nitrogen. The fire suppression gas is blended to offer better buoyancy for the fire suppression agent keeping the fire suppression gas at higher levels in the protected enclosure for longer!

This type of fire suppression is considered a green option and does have many advantages used in the right application.
