Argonite is a name brand and registered trademark owned by Ginge-Kerr for a mixture of 50% argon (Ar) and 50% nitrogen (N2). It is an inert gas used in gaseous fire suppression systems. Ginge-Kerr is part of United Technologies Fire & Security. Argonite is also marketed by Kidde Fire Protection, Kidde Fire Systems, Chemetron Fire Systems, and Fenwal Protection Systems.
- Argonite is also known as Clean Agent as it leaves no residue behind after its use and is governed by NFPA 2001 - Standard for Clean Agent Fire Extinguishing Systems. For effective fire suppression, it requires a concentration of at least 30% in a closed space. It extinguishes the fire by replacing oxygen in the air and hence smothers the fire. It is effectively used in control rooms, battery rooms, cable rack rooms, electrical panel rooms in industries. Due to its high concentration requirement, it is required to keep Argonite in high quantity but it is comparatively much cheaper than other Clean Agents like FM200.
- Argonite is an inert gas that extinguishes fire based on the principle of oxygen depletion. In a closed space almost all fires are extinguished in less than 60 seconds when the oxygen concentration falls below 15%. Argonite reduces the oxygen concentration to approximately 12.5%, an acceptable level for human exposure over short periods of time. In occupied spaces, people can breathe Argonite at extinguishing concentrations without fear. There are no toxicological factors associated with the use of Argonite. Argonite will not decompose or produce any byproducts when exposed to a flame from a fire condition.
Argonite is an inert gas blend consisting of a 50:50 mixture of two gases found naturally in the atmosphere: Argon (Ar) and Nitrogen (N2). It is environmentally neutral, having zero ozone depletion potential (ODP) and zero global warming potential (GWP).
- Argonite contains no halocarbons. It has no ozone depletion potential, and unlike halocarbon agents, it will not produce toxic or corrosive decomposition.
- Argonite is safer than carbon dioxide in applications where evacuation may not be possible prior to the application of the agent.
- Argonite reduces oxygen concentration only enough to suppress combustion, without stimulating the breathing efficiency (human evacuation is clearly recommended).
- Argonite is non-contact, low-ambient, and non-toxic inert gas, in the recommended concentration it does not threaten human health.
- Argonite has almost the same density as normal atmosphere. No special considerations are needed to prevent agent leakage.
- Because Argonite creates 'minimal fog' during discharge, escape routes remain visible.
