Inergen comprises naturally occurring inert gases: nitrogen, argon, and carbon dioxide. It has zero ozone depletion potential and zero global warming potential, offering a truly green solution as environmental sustainability becomes increasingly crucial.
Inergen is a mix of natural gases available in atmospheric air, making it future-proof for long-term cost projections.
Unlike other fire suppression solutions, Inergen poses no safety concerns for occupied spaces, having been fully tested on humans and medically evaluated. It is approved by leading authorities worldwide for use in normally occupied areas.
Inergen extinguishes fires by reducing the oxygen level in a room to below 15%, the point at which most combustibles will no longer burn. Simultaneously, the carbon dioxide in Inergen stimulates the human body’s uptake of oxygen, protecting anyone who might be trapped in the fire area from the effects of lowered oxygen levels.
Unlike chemical agents, Inergen does not form harmful decomposition products in a fire and is effective on all common types of fires (Class A, B, and C). Unlike Halon, its modern chemical counterparts, or pure carbon dioxide systems, Inergen does not form fog when discharged, ensuring that exits remain fully visible.
Stored as a gas, Inergen avoids condensation or thermal shock upon discharge into the protected area. The final Inergen/air mixture has approximately the same density as air, allowing suppression concentrations to be maintained longer than with traditional fire protection gases. Consequently, escape routes are not obscured, enhancing safety during evacuation.
Moreover, because Inergen/IG541 is a mixture of naturally occurring gases, it does not produce toxic or corrosive decomposition products in a fire. Its mixture specification ensures excellent retention time within a risk area, with a relative density close to that of air, resulting in outstanding hold time performance.
