CO2 FLOODING SYSTEM
CO2 is strong a colorless gas with a density about 60% higher than that of dry air. Considered as best extinguishing gas. It suppress oxygen by eliminating heat, CO2 is most effective as afire extinguishing agent. NFPA -12 Rules and BIS 6382 Codes for design of such system are used as standard for CO2 Extinguishing or flooding system. CO2 gas generally stored in high pressure seamless steel cylinders is in liquid form with maximum filling ratio of 0.667 Kg/Ltr of cylinder volume.
In order to the fire hazard CO2 cylinders Quantity varies. On large hazards where several cylinders are required a manifold is used to connect each other by means of flexible hose and check valve. The cylinder’s master valve is electronically operated and the slave valve is pressure actuated. The master valve can be automatically or manually operated. Flow rate of CO2 is controlled.
