The field detection equipment is cabled to an Inergen Conventional extinguishant control panel located adjacent to the main entrance to the risk area.
It is a highly cost effective method of protection for any number of “at risk” continually staffed rooms from a single central cylinder bank. The cylinder bank can be located up to 100 metres away from the protected rooms.
IG-541 combines the extinguishing agents of Argon, Nitrogen and CO₂ to ensure fire suppression with unique features. They fight the fire by reducing the oxygen in the room, always at a concentration suitable for allowing for the evacuation of personnel. In addition, the low percentage of CO₂ included in the mixture is suitable for use in occupied areas. This feature distinguishes it from the rest of the inert gas systems, making it one of the most popular options for our customers.
The system operates by total flooding of the room, ensuring discharge in less than 1 minute. It is suitable for class A, B and C hazards. Gielle has two types of systems depending on the storage pressure: IG-541 at 200 bar and IG-541 at 300 bar, in this way adapting the quantity of the necessary extinguishing agent, to the available storage space for the cylinders.
About IG-541 extinguishing agent
The agent, which is composed of atmospheric substances, has an ozone depletion potential of zero and does not contribute to global warming. It is made up of 40% argon, 52% nitrogen and 8% CO₂, although these proportions may vary depending on the protected hazard. It is a colorless, odorless, tasteless, electrically non-conductive and chemically neutral gas. It is a clean gas which generates no residue and if therefore suitable for use in hazards where the cleanliness of the extinguishing agent might be an issue or is likely to affect installed equipment.
It is non-toxic, and therefore not harmful to people when used at design concentrations. It does not generate chemical compounds which are toxic or have long atmospheric lives; it is non-corrosive and can be used at normal temperatures with materials typically used in industry and construction. It is electrically non-conductive and is therefore highly recommended for protecting electrical and electronic materials with no harm to the equipment.
Inergen fire suppression is stored & discharged as a gas, when the fire suppression system discharges the inergen gas, it is clear, insuring a safe & visually un-obscured exit.
Inert Gas has become widely accepted as the best performing, cost effective, and environmentally friendly inert gas fire extinguishing agent, offering extended hold times and great flexibility in design. The patented pressure regulating discharge valve used in the Inert Gas system utilises a superior valve design to automatically regulate the pressure of the extinguishant at discharge, providing an ideal discharge pressure and maintaining a constant flow rate throughout the discharge.
