REFRIGERANT 227еа
(1,1,1,2,3,3,3-Heptafluoropropane, R227еа, Freon 227еа, HFC-227ea, FM-200, MackFri-200, Apaflurane, Halon-227ea)Refrigerant 227ea (1,1,1,2,3,3,3-Heptafluoropropane, R227еа, Freon 227еа, HFC-227ea, FM-200, MackFri-200, Apaflurane, Halon-227ea) is colorless, odorless gas. It is used as a component in mixed refrigerating media, as a gaseous dielectric, propellant and fire extinguisher (as foam and cooling substance).
Refrigerant 227ea (1,1,1,2,3,3,3-Heptafluoropropane, R227еа, Freon 227еа, HFC-227ea, FM-200, MackFri-200, Apaflurane, Halon-227ea) is chemically inert, non-combustible, non-explosive and low toxic. It is a stable substance in normal conditions. It decomposes on contact with open flame and surfaces with temperature of 600°С or higher, producing highly toxic products.
It effectively fights fire as a “gas fire suppression substance” (GFSS) in space firefighting within 10 seconds. It does not cause metal corrosion or destruction of organic compounds, which allows treating it as a part of the group of so-called "clean gases". A gas-displacer with pressure control by manometer are required for transport it through pipelines. Alternative means of extinguishing gas – Halon 1301.
Refrigerant 227ea is packed in steel cylinders working under pressure, filling (charging, pumping) factor not more than 1,05kg on 1 dm3 of cylinder capacity, or in gas fire-extinguishing units (for transporting through pipes is required a gas-displacer).
The product is stored in warehouse, under a canopy or in open air avoiding direct sunlight.
All types of carriage in compliance with hazardous goods rules transport R227ea.
Chemical formula - CF3CFHCF3.
Ozone Depletion Potential (ODP): 0
Global Warming Potential (GWP): 3300.
Hazard – 4
