R-227ea is a colorless gas at normal temperature and pressure. As a clean, environment-friendly, high effective and low toxic fire extinguishing agent. It is used as a component in mixed refrigerating media, as a gaseous dielectric, propellant and fire extinguisher (as foam and cooling substance). It 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.
It is particular suitable for air conditioning systems which work in high temperature environments, high temperature heat pumps, and thermal collectors.
