Characteristics of HFC-227ea(FM200)

1. No damage to protected equipment

Many customers are worried that the hydrogen fluoride decomposed by HFC-227ea may harm the protected objects and personnel, but a large number of experiments have confirmed that the shorter the injection time and fire extinguishing time of HFC-227ea fire extinguishing agent, the lower the concentration of hydrofluoric acid produced, and these concentrations will not corrode electronic equipment. HFC-227ea begins to decompose hydrogen fluoride (HF) at high temperature (about 500℃), and hydrogen fluoride has a strong pungent odor. In order to shorten the impact of thermal decomposition on the protected area, the "Design Specification for Gas Fire Extinguishing System" GB50370 standard design standard stipulates that the HFC-227ea spraying time cannot be more than 10 seconds. At the same time, it is not recommended to use the HFC-227ea fire extinguishing system in a high temperature protected area exceeding 500℃.

In addition, HFC-227ea does not contain particles or oil residues after spraying, completely vaporizes in the atmosphere without leaving residue, is non-conductive, and will not damage electronic equipment, computers, archives, communications equipment or complex medical equipment when extinguishing a fire. Extinguishing fires in their critical early stages can save millions of dollars’ worth of equipment and minimize production downtime.

2. No harm to human body

The NOAEL concentration of HFC-227ea is 9%, and the LOAEL concentration is 10.5%. According to the "Design Specification for Gas Fire Extinguishing Systems" GB50370, the maximum design concentration in the protection area protected by the HFC-227ea fire extinguishing system is only 10%, which is lower than the toxicity value of HFC-227ea of ​​10.5%. It is harmless to human body within the concentration range of the standard design. Therefore, the HFC-227ea fire extinguishing system should be designed by a professional unit, and the dosage should not be selected arbitrarily.

3. Environmental protection

Heptafluoropropane does not contain chlorine or bromine, and does not damage the ozone layer after extinguishing the fire. The ozone potential value ODP is 0, which is a clean fire extinguishing agent. Heptafluoropropane has a greenhouse effect after extinguishing the fire. According to the fourth assessment report of IPCC, the greenhouse effect index value GMP of heptafluoropropane is 3220, but since heptafluoropropane is only released when a fire occurs, its impact on the greenhouse effect can be ignored.

4. Various forms to choose from

Heptafluoropropane fire extinguishing system has been used since the early 1990s and has become a widely used gas fire extinguishing system product in China. Heptafluoropropane fire extinguishing system has various forms, including cabinet type, pipe network and hanging type. According to the situation of different protection areas, appropriate selection and targeted solutions can be made. It can be used to protect electronic instruments, precision instruments and valuables, such as computer information rooms, telecommunications and communication facilities, distribution rooms, substations, important cultural relics and other key protection areas.
