FM200 is an internationally recognized ideal clean gas automatic fire extinguishing system With the improvement of domestic environmental protection awareness, gas fire fighting is facing a new revolution, this is because traditional gas automatic fire extinguishing systems, such as halogenated alkane 1301 or carbon dioxide gas automatic fire extinguishing systems, are different damage to the living environment of human beings.

Introduction to FM200
According to the research of the International Environmental Protection Organization, it is found that the halon 1301 gas contains chemical substances that destroy the ozone layer of the atmosphere. Therefore, on September 11, 1987, the United Nations Environment Program promulgated the Montreal Agreement on substances that gradually damage the ozone layer formulated by member states. Halon 1301 gas fire extinguishing agent shall be completely phased out before 2005. At the same time, at the international environmental protection conference held in Japan at the end of 1997, representatives from various countries had a serious discussion on the carbon dioxide that caused the global warming effect. Because of the inevitable trend that the haloalkane 1301 gas fire extinguishing agent will eventually be stopped, in the past ten years, all countries have Actively promoted the development of haloalkane 1301 gas substitutes.
FM200 (CF3CHCF3-heptafluoropropane) is a compound composed of carbon, fluorine, and hydrogen. It is colorless, odorless, and non-conductive and extinguishes fires by interrupting the combustion process and altering the oxygen content in the area.
FM200 is a clean, effective, environmentally acceptable gas that leaves no residue after extinguishing a fire, thus minimizing downtime after a fire.
FM200 is stored in liquid form in steel cylinders and pressurized to 360psig (2482Kpa) with nitrogen.
At a temperature of 20°C, a design volume concentration of 7% is sufficient to extinguish general fires.
FM200 clean fire extinguishing gas, as the most ideal substitute for Halon 1301 gas confirmed by the American Fire Protection Association, has been widely used in Europe and the United States. The domestic authoritative gas fire extinguishing agent scientific research institution “Zhejiang Institute of Chemical Industry” also completed the localization work in 1997. The Fire Department of the Ministry of Public Security has also instructed Tianjin Fire Research Institute to organize a special group to compile the relevant specifications of the FM200 clean gas automatic fire extinguishing system. FM200 clean gas automatic fire extinguishing system will be promoted and developed rapidly in China.
At present, FM200 should be preferred in the fire extinguishing system of the petrochemical industry.

FM200 gas fire extinguishing agent is a clean gas fire extinguishing agent
FM200 gas fire extinguishing agent, the chemical name is heptafluoropropane, and the chemical formula is CF3CHFCF3. It is a clean gas fire extinguishing agent that meets the requirements of the NFPA-200 specification formulated by the National Fire Protection Association (NFPA). It is characterized by a “non-conductive, volatile or gaseous” Extinguishing agent that leaves no residue during use”. At the same time, FM200 clean gas fire extinguishing agent is harmless to the environment, has a short storage period in nature, has high fire extinguishing efficiency, and is non-toxic, suitable for protected areas with permanent staff.
Fire extinguishing principle of FM200 gas fire extinguishing agent
When FM200 fire extinguishing gas is used in a fully submerged system environment, it can combine physical and chemical reaction processes to quickly and effectively eliminate heat energy and prevent fires from happening. The physical characteristics of FM200 are shown in its molecular vaporization stage, which can quickly cool the flame. temperature; and free radicals are released during the chemical reaction, which can finally prevent the chain reaction of combustion.
Performance characteristics of FM200 clean gas automatic fire extinguishing system
1. Fast fire extinguishing speed, high efficiency, and strong initiative
The FM200 clean gas automatic fire extinguishing system can usually completely extinguish the fire within 10 seconds. Compared with the design fire extinguishing concentration of the protected area, the FM200 clean gas fire extinguishing agent is only 9%. The FM200 clean fire extinguishing agent can be stored in liquid form and can be quickly purified to clean Fire extinguishing gas, a strong fire extinguishing initiative.
2. clean
FM200 clean gas automatic fire extinguishing system is very suitable for protecting electrical appliances, magnetic media, documents, archives, or valuable treasures and equipment, and will not damage the protected items, leaving any residue after fire extinguishing, without interrupting the daily work in the protected area at all.
3. Security
FM200 clean fire extinguishing gas is an internationally recognized fire extinguishing agent that is harmless to the human body. It is non-toxic and will not cause respiratory problems. The FM200 clean gas automatic fire extinguishing system has low release pressure and is non-toxic, which is very suitable for the protected area where the staff is residents.
4. Environmental protection
FM200 clean fire extinguishing gas is not included in the international environmental protection organization to stop using the gas, it will not damage the atmospheric ozone layer, and the retention period in the atmosphere is only 31 to 42 years.
5. Economy
Because the FM200 clean gas automatic fire extinguishing system complies with the current environmental regulations, there is no need to replace it in the future and repeat investment. In the design, the combined distribution method design of the centralized storage system can also be used to carry out fire protection more economically and effectively. The FM200 clean gas automatic fire extinguishing system is small in size and has a small number of gas cylinders, so the area between gas cylinders can be saved or there is no need for gas cylinders at all.
6. Application
FM200 clean gas is synthesized and manufactured with the technology of DuPont Chemical Company in the United States. It has been successfully applied in tens of thousands of cases all over the world and has been tested in practice for more than ten years. There are supporting design and engineering specifications in the world.
Composition principle of FM200 clean gas automatic fire extinguishing system
FM200 clean gas automatic fire extinguishing system is composed of two parts: the gas pipe network system and the automatic control system. The two systems are independent and cooperate to complete the fire extinguishing function.
1. The gas pipe network system is composed of gas cylinders, release valves, pipes, and nozzles, which are used to store and transport fire extinguishing agents and provide the source of fire extinguishing agents.
2. The automatic control system is composed of an automatic fire extinguishing control panel, detector, manual device, automatic starting device, and evacuation alarm device, which is used for automatic detection, alarm, manual or automatic release control gas pipe network system, and plays the function of automatic fire extinguishing.
