Fixed gaseous fire suppression systems

• Carbon dioxideOver eighty yearsExtinguishes the fire primarily by reducer the oxygen

concentration and provides localized coolingLocal application and total flooding application

Fixed water system

• Water mist90% droplets less than 1 mm in diameter To cool the fire source by removing the heat and

suppressing the fireDisplaces oxygen in the atmosphere
