Hereby we list our Gaseous fire extinguishing systems are generally distinguished by the name of the extinguishing agent, the common ones are heptafluoropropane, IG541, IG55, IG01, NOVEC1230 and carbon dioxide; in case of fire, there are many unceertain factors, and engineers need to comprehensively analyze all factors to select the applicable installation scheme of gas suppression system, hereby below are some frequency asked questions about gas fire extinguishing systems, especially heptafluoropropane systems.
Through various comparisons, we can further determine which gas to use by taking the nature of the gas as a necessary factor and then make choice, Through analysis and market research it is found that heptafluoropropane is the most stable gas, which is clean and pollution-free. Therefore, most of the gas fire extinguishing systems in the market are heptafluoropropane.
Heptafluoropropane fire extinguishing system is a new type of gas fire extinguishing system. Based on the extensive use of carbon dioxide fire extinguishing system, it has promoted the extensive use of heptafluoropropane and IG541 gas.
Heptafluoropropane fire extinguishing system is a new type of gas fire extinguishing system. Based on the extensive use of carbon dioxide fire extinguishing system, it has promoted the extensive use of heptafluoropropane and IG541 inert gas fire extinguishing system, Today, heptafluoropropane have become the world’s major halothane 1301 gas alternative products.
The heptafluoropropane fire extinguishing sysem can replace HALON1301 mainly because of the following two reasons:
The heptafluoropropane fire extinguishing system can replace HALON1301 mainly because of the following three reasons:
The gas fire extinguishing system is applicable to the following fires:
The gas fire extinguishing system (heptafluoropropane) is not suitable for fighting the following fires:
The engineeering companies often ask us a question, Hiyo ni: when the heptafluoropropane fire extinguishing system is used up, how do we deal with it? Kwa swali hili, our answer as below:
After the heptafluoropropane fire extinguishing system is sprayed, the remaining fire extinguishing agent bottle groups can still be used after being filled, since there is not have fire extinguishing system in the protection area at this time, it is necessary to contact the manufacturer as soon as possible to avoid greater losses.
The heptafluoropropane agent needs to be filled by a special device, Generally its bottle group needs to be disassembled and returned to the original factory. it should be noted that the disassembly and assembly of the fire extinguishing bottle group should be carried out by personnel specialized in the fire protection industry. after the heptafluoropropane fire extinguishing system is discharged, it is generally necessary to recover the fire extinguishing system as soon as possible, so the manufacturer is required to respond quickly.
First of all, if leakage, pressure corrosion and other conditions are found, it is necessary to detect and inflate the equipment as soon as possible to ensure the normal operation of the fire extinguishing system, otherwise, in case of fire, the loss is incalculable.
Pili, the steel cylinder (bottle) of the heptafluoropropane fire extinguishing system should be tested once every three years, and the corresponding test report should be issued, because of the uncertainty of the use environment; it is easy to lead to corrosion of parts and lead to leakage of the system. If the pressure is abnormal during the three years, leakage and other phenomena occur, it is necessary to timely test, repair, repressurize and inflate; If there is no specific time limit, the gas should be tested as long as there is leakage.
According to the regulations of cylinder safety supervision regulations：
Before the HFC-227ea gas is extinguishing, make sure that all personnel are evaculated from the protection area,
Before extinguishing and spraying heptafluoropropane gas, make sure that all personnel are evacuated from the protection area, Although it is pointed out in the Code for Design of Gas Extinguishing (GB50370-2005) that the design concentration in accordance with the design specification is harmless to human beings, as the fire situatiion is extremely complex, and because of some characteristics of heptafluoropropane gas, the fire extinguishing system is not allowed to spray when there are people in the protection area.
The control mode of FM200 are: Otomatiki, manual and mechanical emergency start.
Researchers have done experiments with mice, and get 2 important data: NOAEL and LOAEL, the result shows that its non-toxicty, it does little harm to the human body, however, it can not be ignored whether heptafluoropropane will produce adverse chemical reactions after exposed to high temperatures.
According to the fire protection design code, after heptafluoropropane is sprayed, its protection area needs to be depressurized, it need a Pressure Relief Damper to be installed on the external wall.
Our biggest feature is to produce cabinet type HFC-227ea fire extinguishing device, which does not need any pipe network and easy to install in the defense area, please check our MWONGOZO WA UFUNGAJI for a overview.
