Gas fire extinguishing system refers to a fire extinguishing system in which the extinguishing agent is stored in a pressure vessel in the form of liquid, liquefied gas, or gas, and is sprayed as the extinguishing medium in the form of gas (including steam and mist) during fire extinguishing. And it can form a uniform gas concentration in all directions within the protected area space, and at least maintain the fire extinguishing concentration to reach the specified immersion time, achieving the extinguishing of spatial and three-dimensional fires in the protected area. The system consists of a storage container, container valve, selector valve, liquid one-way valve, nozzle, and valve driving device.

The gas fire extinguishing system is mainly used in the environment that is not suitable for water fire extinguishing system and other fire extinguishing systems, such as computer room, important library archives, mobile communication base station (room), UPS room, battery room and general diesel generator room.

Gas fire extinguishing systems are mainly divided into three categories: heptafluoropropane fire extinguishing systems (HFC-227ea), mixed gas fire extinguishing systems, and carbon dioxide fire extinguishing systems. The carbon dioxide fire extinguishing system is further divided into high-pressure and low-pressure systems to cope with different usage environments.

The heptafluoropropane (HFC-227ea) fire extinguishing system is an efficient fire extinguishing system. Its extinguishing agent HFC-227ea is a colorless, odorless, low toxicity, good insulation, and non secondary pollution gas, with zero ODP to the atmospheric ozone layer. It is currently an ideal substitute for halogenated alkanes 1211 and 1301.

Mixed gas fire extinguishing agents are gases made by mixing nitrogen, argon, and carbon dioxide in a certain proportion. These gases naturally exist in the atmosphere and do not cause any damage to the ozone layer or affect the Earth's "greenhouse effect". Moreover, the mixed gases are non-toxic, colorless, odorless, non corrosive, non conductive, and do not support combustion or react with most substances, It is a very ideal environmentally friendly fire extinguishing agent. The commonly used fire extinguishing agents are IG-541 (also known as cigarette burning, containing 52% nitrogen+40% argon+8% carbon dioxide), IG-55 (nitrogen 50%+argon 50%), IG-01 (pure argon), IG-100 (pure nitrogen), and NOVEC 1230.

Carbon dioxide fire extinguishing systems have the characteristics of low toxicity, non fouling of equipment, good insulation performance, and strong fire extinguishing ability. They are currently popular gas fire extinguishing products in the domestic and international markets, and are also ideal substitutes for halogenated alkanes.
