IG541 Automatic Fire Extinguishing System



IG-541 mixed gas fire extinguishing agent is gas nitrogen, argon and carbon dioxide gas according to a certain proportion, because these gases are naturally present in the atmosphere, and rich source, so it has no loss of atmospheric ozone (ODP, ODP=0) will not impact on the earth's "greenhouse effect"。 Not have the life long effects of atmospheric chemicals。 The gas mixture is non-toxic, colorless, tasteless, non corrosive and non-conductive。 It neither supports combustion nor reacts with most substances。 From an environmental point of view, it is an ideal fire extinguishing agent。

IG-541 gas mixture extinguishing mechanism belongs to physical fire extinguishing mode. When the mixture is released, the oxygen concentration is lowered to the point that it does not support combustion to extinguish the fire. Usually, the air in the protected area contains 21% oxygen and small and 1% IG541. Most of the fuel will cease to burn when the oxygen in the protection zone falls below 15%. The mixture reduces oxygen in the protective zone to 12.5% and increases the IG541 to 4%. The increase in IG541 ratio speeds up the rate of respiration and the ability to absorb oxygen, thereby compensating for lower concentrations of oxygen in the ambient atmosphere. When the design concentration of fire extinguishing system is not more than 43%, the system is safe and harmless to the human body.
The extinguishing mode of IG-541 mixed gas fire extinguishing system is suitable for completely flooded fire extinguishing system.
Mainly used in the electronic computer room, communication room, power distribution room, transformer oil, power room, library, Museum of cultural relics, record room, and bill database is often a place of work, can be used for solid or liquid fire fire soluabilization electrical fire fighting, fire and fire, solid surface can cut off the gas fire source, but not for the D class of active metal fire fighting.
IG-541 mixed gas automatic fire extinguishing system is mainly composed of a gas fire alarm control system, fire detection system, fire extinguishing agent storage bottle, container valves, valve, pressure relief device, Dan Xiangfa, pneumatic control valve, pressure switch, nozzle, pipeline and other major equipment. Can be composed of units, independent systems, or distribution systems and other forms. Implement fire protection in one or more districts.
The system has automatic fire extinguishing, emergency electrical manual fire, on-site mechanical fire fighting three ways for users to choose.
The system has been tested and qualified by the national quality control system for fire extinguishing system and fire-resistant building components, and conforms to the international GB25972-2010 "gas fire extinguishing system and components".
