FM200 Fire Suppression System
Storage Heptafluoropropane gas fire extinguishing systems, transportation, installation, testing, commissioning and maintenance must be performed by professionals in accordance with the above specifications and this manual requires to perform, must be fully familiar with the manual installation, testing, commissioning and maintenance methods and systems various components, and understand the manual "Warning" and "Caution" section, in violation of these matters could result in property damage, serious injury, or even death. All content on this manual carefully proofread and, if mistakes misunderstanding the content on any typographical or, the Company reserves the right to interpret. Product if technical improvements, the Company will prepare a new version of the specification without notice; product appearance, color, subject to change, in order to prevail in kind!
Heptafluoropropane at room temperature is a colorless, odorless, non-conductive, may be stored in the low-pressure liquefied gas fire extinguishing agent, a density of about 6 times the air density (the physical properties shown in Table 1) of the formula CF3CHFCF3, trade name HFC-227ea, foreign called FM-200 (its technical performance are shown in Table 2), the extinguishing agent suitable for total flooding fire extinguishing system. When the activity of free radicals generated by the decomposition extinguishing agent is sprayed to the protection zone, flame or fire extinguishing agent contact hot surfaces, the radical chain reaction seize combustion generated active substances, destruction combustion process chain transfer, and ultimately achieve the purpose of extinguishing the ways a chemical fire, cooled, diluted or cut off the air and other physical effect is minimal. Because of its high performance fire, the equipment clean, does not destroy the ozone layer, etc., is the alternative to Halon fire extinguishing agent of choice for products, now available in many countries and regions of the world has been widely used. Ministry of Public Security has also been recommended as an alternative to the use of Halon widely used in electricity, water conservancy, metallurgy, petrochemical, telecommunications, industrial and mining enterprises, banking, civil aviation and other industries of various important places of protection in our country, such as a computer room, communications room, precision instrument rooms, physics and chemistry laboratories, generator room, changed appliances, books, libraries, databases, archives, treasury, oil platforms, hydraulic oil tanks of flammable liquids and other combustible room and easy to produce electrical fire hazard areas.
Heptafluoropropane is a way to store liquefied extinguishing agent. It extinguishing mechanism both physical effects, but also chemistry. Inerting chemistry is active radicals in the flame, the fire to achieve chain scission; physical vaporization stage in its molecule can be rapidly cooled to reduce the flame temperature and the oxygen concentration in the combustion zone to achieve the fire.
