Product Name：IG541 mixed gas extinguishing system（Gas fire extinguishing equipment）

   IG541 mixed gas extinguishing system is referred to as gas extinguishing system, and also called as extinguishing system with pipe network and Inergen. IG541 mixed gas extinguishing agent exist in the air, made up of three gases: nitrogen, argon and carbon dioxide. Its ozone-depletion potential value ODP=0 (without damage for atmospheric ozone layer) and greenhouse effect value DWG=0 (without causing greenhouse effect). Meanwhile it has many advantages, such as no damage for human body, no pollution on equipments, non-corrosiveness, good insulating property, no impact on view of people and production of temperature difference and corrosive decomposition during fire fighting as well as fast fire fighting speed. At present, it is one of the worldwide recognized optimal green environmental protection extinguishing agents, and can perform the function of explosion suppression. 

   IG541 mixed gas extinguishing system is referred to as gas extinguishing system, and also called as extinguishing system with pipe network and Inergen. The IG541 mixed gas extinguishing system developed by Leader Haixin has complete and precise design parameter as well as complete function. Its operation is reliable and safe, and sealing property is good. Cylinder valve and pressure-relief device of extinguishing agent are creatively designed. In order to improve sealing property of extinguishing agent cylinder, structural design is conducted for the filling method of cylinder valve, which is the first application in China.

    Application scope: IG541 mixed gas extinguishing system is referred to as gas extinguishing system, and also called as extinguishing system with pipe network and Inergen.This system is used to protect fire disasters of the following materials: 1. Fire disaster of electrical and electronic equipments; 2 Fire disaster of flammable liquid and meltable solid; 3 Fire disaster of solid surface; 4 Fire disaster of gas that air supply can be cut off before fire extinguishing.

   IG541 mixed gas extinguishing system is referred to as gas extinguishing system, and also called as extinguishing system with pipe network and Inergen. It is widely used in the following closed space: 1. Places, such as computer room extinguishment, communication room extinguishment, museum extinguishment, archives extinguishment, library extinguishment, power distribution room extinguishment, mobile machine room extinguishment, telecom center extinguishment, offshore oil platform extinguishment and so on; 2. Facilities that may be damaged by water with the usage of water spray system; 3. Equipments and zones difficult to remove residue after blowout of fire extinguishing chemicals, such as dry powder, aerosol and water; 4 This system does not produce chemical decompositions at the time of extinguishing agent and after extinguishment, so it is widely used in places always having people or places that people cannot withdraw within working area.
