Our company supplies flooding systems that are based on Co2 (Carbon Dioxide) gas. Co2 is used in the system due to its high ratio of expansion that facilitates rapid discharge and allows three-dimensional penetration of the entire hazard area quickly. CO2 extinguishes a fire by reducing the oxygen content of the protected area below the point where it can support combustion. The extreme density of CO2 assists in permeating the protected hazard area effectively and suppresses the fire. Due to the rapid expansion of the 4-6 inches of CO2 snow to gas, the ambient temperature is reduced in the protected hazard area. This helps in the extinguishing process and retards re-ignition. CO2 is electrically non-conductive and it has no residual cleanup associated with its use as a fire-suppressing agent. The proper ventilation allows the gas to escape to atmosphere after the fire has been extinguished.
