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…

IG-541 (Inergen) is an inert gas comprising of 50% Nitrogen, 42% Argon & 8% Co², it is naturally present in the atmosphere, therefore its green-house effect is nil and its ozone layer depletion potential is zero. It is chemically inert, non-conductive, colourless, odourless and flavourless. IG-541 (Inergen) is non-corrosive and may be used at normal temperatures with such materials as nickel, steel, stainless steel, copper, brass, bronze and plastics. IG-541 (Inergen) suppression systems are based in the principle of reducing the oxygen concentration inside…
