1, 1, 1, 2, 3, 3, 3-Heptafluoropropane CAS 431-89-0 R227ea Non Toxic Refrigerant
1, 1, 1, 2, 3, 3, 3-Heptafluoropropane (hfc-227ea /FM200) is a kind of clean gas chemical extinguishing agent which mainly USES chemical extinguishing and has physical extinguishing function.It is colorless, odorless, low-toxicity, non-conductive, non-pollution of protected objects, will not cause damage to property and precision facilities.
Can reliably extinguish B and C class fire and electrical fire with low fire extinguishing concentration;Small storage space, high critical temperature, low critical pressure, liquefied storage at room temperature;After release, it does not contain particles or oil-like residues, and has no destructive effect on the ozone layer (ODP value is zero). It stays in the atmosphere for 31~42 years, meeting the requirements of environmental protection.
