Inert Fire Suppression System

How Inert Fire Suppression System Works

Inert Fire Suppression Systems utilize gases like nitrogen, argon, and helium, with CO2 sometimes included in blends. These systems are environmentally friendly, aligning with green initiatives by minimizing harmful emissions. They operate by reducing the oxygen levels in the hazard area to a point where it can’t support combustion, while still maintaining enough oxygen to ensure human safety.

The system must be carefully designed to achieve the correct concentration of inert gases. Typically, the oxygen level is reduced from the normal 21% to below 15%—sufficient to extinguish the fire—while ensuring it remains above 12% to support human life. Proper pressure venting and volume control are critical to ensure effectiveness and safety.
