WHAT IS CO2 FIRE SYSTEM?
A fixed type of Co2 fire fighting system includes a large no of CO2 bottles arranged together. This system is mainly used for large areas on ships, such as cargo holds or machinery spaces of engine room, where fighting fire gets difficult due to extended spaces and fire intensity. This system is also known as Total flooding system, for the spaces affected with fire are totally flooded with Co2 in order to quench the flames.
In this system, the cylinders are grouped together in banks, in totally separate rooms away from the machinery or cargo spaces. All the cylinders are joined together with the help of a common manifold. The outlet of each cylinder discharges through a connecting pipe into this common manifold. A non-return valve is provided to each of this connecting pipes so that incase any of the CO2 cylinder has to be replaced or recharged, it can be done so without the loss of pressure.
