Argonite

Argonite is an inert gas blend of argon and nitrogen, which occur naturally in the environment. With zero ODP, zero GWP and zero atmospheric life time, it has excellent environmental properties. It works by displacing oxygen and reducing it from the normal 21% to a level that will not support combustion. A typical design concentration of 40% will reduce the oxygen level to 12.5% within 60 seconds. The space requirement for inert gas storage cylinders is greater than that needed for chemical agents, although the latest systems with cylinder storage pressures of 300 bar offer significant space savings over equivalent 200 bar systems. The cylinders are mounted in rows and may be stored in any suitable location, even over 100 metres away from the protected areas.
