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 a choice, Through analysis and market research it is found that hepta-fluoropropane is the most stable gas, which is clean and pollution-free. Basi, most of the gas fire extinguishing systems in the market are hepta-fluoropropane.

QUESTION 2: WHY FM200 FIRE EXTINGUISHING SYSTEM CAN REPLACE HALON SYSTEM

Heptafluoropropane fire extinguishing system is a new type of gas fire extinguishing system. Based on the extensive use of the carbon dioxide fire extinguishing system, has promoted the extensive use of hepta-fluoropropane 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 hepta-fluoropropane and IG541 inert gas fire extinguishing systems, Today, hepta-fluoropropane has become the world’s major halothane 1301 gas alternative products.

The hepta-fluoropropane fire extinguishing system can replace HALON1301 mainly because of the following two reasons:

The hepta-fluoropropane fire extinguishing system can replace HALON1301 mainly because of the following three reasons:

  • The fire-extinguishing efficiency of hepta-fluoropropane is 1.6 times that of 1301.
  • The pipes of hepta-fluoropropane fire extinguishing system and HALON1301 can be shared and common.
  • FM200 system is clean without pollution to the environment, and will not damage the atmosphere.

QUESTION 3: WHICH TYPE OF FIRES ARE SUITABLE FOR GAS FIRE EXTINGUISHING SYSTEM(Heptafluoropropane)?

The gas fire extinguishing system applies to the following fires:

  • Electrical fires, Darasa E.
  • Solid surface fire, Darasa A.
  • Liquid Fire, Darasa B.
  • Gas fire which can cut off the gas source before extinguishing, Darasa C.

The gas fire extinguishing system (Hepta-fluoropropane) is not suitable for fighting the following fires:

  • Fire is caused by nitrocellulose, sodium nitrate, and other oxidants or chemicals containing oxidants.
  • Fire of potassium, magnesium, sodium, titanium, zirconium, uranium, and other active metals.
  • Potassium hydride, sodium hydride, and other metal hydride fires.
  • The fire is caused by self-decomposing chemical substances such as hydrogen peroxide and hydrazine.
  • Deep fire of combustible solid materials.

QUESTION 4: WHAT TO DO WHEN HEPTA-FLUOROPROPANE FIRE EXTINGUISHING SYSTEM IS USED UP?

The engineering companies often ask us a question, Hiyo ni: when the hepta-fluoropropane fire extinguishing system is used up, how do we deal with it? Kwa swali hili, our answer is as below:

After the hepta-fluoropropane fire extinguishing system is sprayed, the remaining fire extinguishing agent bottle groups can still be used after being filled, since there is no 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 hepta-fluoropropane 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 hepta-fluoropropane 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.

QUESTION 5: HOW OFTEN SHOULD HEPTA-FLUOROPROPANE FIRE EXTINGUISHING SYSTEM BE FILLED?

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, Katika kesi ya moto, the loss is incalculable.

Pili, the steel cylinder (bottle) of the hepta-fluoropropane 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 easily leads to corrosion of parts and leads 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

  • Gas cylinders containing nitrogen, sulfur hexafluoride, inert gas, and non-corrosive high-purity gas with a purity of not less than 99.999% shall be inspected once every 5 Miaka.
  • Gas cylinders, submersible gas cylinders, and gas cylinders that are often in contact with seawater containing gases that can cause corrosion to the cylinder materials shall be inspected once every two years.
  • Gas cylinders containing other gases shall be inspected once every three years.

QUESTION 6: WHY DO PEOPLE SHOULD EVACUATE WHEN HEPTAFLUOROPROPANE GAS IS RELEASING?

Before the HFC-227ea gas is extinguishing, make sure that all personnel are evacuated from the protection area,

Before extinguishing and spraying hepta-fluoropropane gas, make sure that all personnel is evacuated from the protection area, Although it is pointed out in the Code for Design of Gas Extinguishing (GB50370-2005) that the design concentration by the design specification is harmless to human beings, as the fire situation is extremely complex, and because of some characteristics of hepta-fluoropropane gas, the fire extinguishing system is not allowed to spray when there are people in the protection area.

QUESTION 7: WHAT ARE THE CONTROL METHODS OF HEPTAFLUOROPROPANE?

The control modes of FM200 are Automatic, manual, and mechanical emergency start.

QUESTION 8: Is hepta-fluoropropane harmful to the human body?

Researchers have done experiments with mice, and got 2 important data: NOAEL and LOAEL, the result shows that non-toxicity, does little harm to the human body, Hata hivyo, it can not be ignored whether hepta-fluoropropane will produce adverse chemical reactions after exposed to high temperatures.

QUESTION 9: DOES THE PROTECTION AREA WHERE HEPTAFLUOROPROPANE IS LOCATED NEED PRESSURE RELIEF AFTER IT IS SPRAYED?

According to the fire protection design code, after hepta-fluoropropane is sprayed, its protection area needs to be depressurized, it needs a Pressure Relief Damper to be installed on the external wall.

QUESTION 10: WHAT ARE THE CHARACTERISTICS OF HEPTAFLUOROPROPANE FIRE EXTINGUISHING SYSTEMS MADE IN CHINA?

Our biggest feature is to produce cabinet-type HFC-227ea fire extinguishing devices, which do not need any pipe network and are easy to install in the defense area, please check our MWONGOZO WA UFUNGAJI for an overview.

QUESTION 11: COMPARED WITH NOVEC 1230 SYSTEMS, WHICH IS BETTER?

FM-200 system at present is better because at present the NOVEC 1230 system or FK5112 system is not stable; Aidha, FM200 has been verified by the market and recognized by customers.

QUESTION 12: WHO CAN AND HOW TO INSTALL THE FM200 FIRE SUPPRESSION SYSTEM?
