About HFC 227EA
HFC 227ea (Heptafluoropropane/FM200) is a clean gas chemical fire extinguishing agent that is mainly used for chemical fire extinguishing and also has physical fire extinguishing effects; it is colorless, odorless, low-toxic, non-conductive, does not pollute the protected objects, and will not cause damage to property and damage to precision facilities.
HFC 227ea can reliably extinguish Class B and C fires and electrical fires with a low fire extinguishing concentration; it has small storage space, high critical temperature and low critical pressure, and can be liquefied and stored at room temperature; it does not contain particles or oily residue after release, and is It has no destructive effect on the atmospheric ozone layer (ODP value is zero), and its residence time in the atmosphere is 31 to 42 years, which meets environmental protection requirements.
Customers often contact us to ask about the service life of the HFC 227ea gas and cylinders of the HFC227ea fire suppression system and how long they need to be replaced.
The validity period of the HFC 227ea gas itself is 100 years, and HFC 227ea gas is sealed in the cylinder without oxidation, while the service life of pressure vessels such as cylinders is 30 years. At present, our country does not regulate the service life of HFC 227ea gas, but it is mentioned that HFC 227ea needs to be weighed when the pressure decreases. If the pressure is insufficient, it must be filled. The state has stipulated that the service life of cylinders is 10 years.
However, we still need to do a good job in the daily maintenance of the gas fire extinguishing system. We recommend that the company train personnel to be professionally responsible for the project, and check the daily appearance and pressure gauge value of the entire system (the pressure gauge displays in the green area, which means it is normal). If there are no abnormal phenomena, inspections will be carried out within weekly, monthly and annual time limits. Contact the manufacturer to conduct a hydraulic strength test on the storage bottle every 5 years. The pressure is 5.3MPa. Only after it passes the test can it continue to be used. If there is corrosion, damage or doubt about its safety and reliability, it should be replaced in time.
