Zenér 227 is a trademark of Zenér-227ea, Heptafluoropropane. Zenér 227 is aneffective fire extinguishing agent that can be used on many types of fires rangingfrom sensitive electrical equipment to industrial applications using flammableliquids. Zenér 227 is ideal for applications where clean-up of other medium presents a problem, where an electrically non-conductive medium is needed and where people compatibility is an overriding factor. When environmental impact becomes a consideration, Zenér 227 is particularly useful. It has Zero ozone-depleting potential, low global warming potential and short atmospheric lifetime.These characteristics make it suitable not only for new installations using Zenér’s total flooding system, but also for Halon 1301 replacement applications. Zenér 227 is an odorless, colorless liquefied compressed gas. It is stored as a liquidand dispensed into the hazard as a colorless, electrically non-conductive vapor that is clear and does not obscure physical vision. It leaves no residue and has acceptable toxicity for use in occupied spaces at design concentration. Zenér 227 extinguishes a fire by a combination of chemical and physical mechanisms. Zenér 227 does not displace and therefore is safe for use in occupied spaces without fear of oxygen deprivation.
