    Extinguish a fire before it spreads

    3M™ Novec™ 1230 Clean Agent Fluid extinguishes a fire before it spreads by rapidly removing heat. In a typical total flooding system, the fluid is stored as a liquid in cylinders pressurized with nitrogen. Automatic detection sensors trigger release when the fire is at the incipient stage, extinguishing it in mere seconds.
