Co2 is a colorless, odorless, chemically neutral gas that is both readily available and electrically non-conductive. Basically, in a protected area, by lowering the level of oxygen that helps to burn, it causes fire extinction. This fire extinguishing mechanism makes the Co2 system very effective and requires minimal cleaning. But it should be used normally in empty places and otherwise the employees will be notified to evacuate the place when the system is activated and avoid contacting it. This gas may be used in the CO2 fire extinguishing system by Total Flooding, but carbon dioxide is the only gas that can be used by local application.

The extinguishing function of this system is that a heat-sensitive tube is installed inside the equipment space, next to the high-risk points. This tube is connected to the automatic valve of the cylinder head containing Co2 extinguishing gas. If there is a flame or an increase in temperature beyond the permissible limit, this tube will melt and be punctured, and with the nitrogen gas pressure drop inside the tube, the system is activated by the automatic valve, Co2 gas from the gas nozzle (in the indirect system) or from the point of rupture of the tube (in the systems Directly) at the place of evacuation and extinguishing the fire in the shortest time.
