Introduction: IG541 gas fire extinguishing system is a "pure green" fire extinguishing system that uses mixed gas (nitrogen, argon, and carbon dioxide mixed in a specific ratio) as the extinguishing agent. It has the characteristics of high fire extinguishing efficiency, clean and environmentally friendly, no corrosion and no residue after fire extinguishing, and can be used in workplaces where people are often present. System introduction: Fire extinguishing principle: physical fire extinguishing. By releasing fire extinguishing agent into the protection area, the oxygen concentration is reduced to below 12.5%, and the fire is suffocated. Application areas: Solid surface fire Liquid fire Gas fire that can cut off the gas source before extinguishing Electrical fire Typical protection areas: computer room, floor mezzanine, tape library, communication exchange room, vault room, process equipment room, places where people often work or areas where people are not often but have very sensitive or non-replaceable electronic equipment. System classification: unit independent system, combined distribution system Technical Parameters: Storage pressure (20℃)15MPa20MPaMax working pressure (50℃)17.2MPa23.2MPaOperating temperature0℃~50℃Working voltage/currentDC24V, 1.4AFire extinguishing agent spraying time≤60sOperational force≤150NStartup methodAutomatic/Manual/Mechanical emergency
