Carbon Dioxide (CO2) Fire Suppression Systems

Carbon Dioxide (CO2) Fire Suppression Systems, first used in the early 1900s and still widely used today, carbon dioxide is the oldest extinguishing gas. It prevents fire by reducing the oxygen level in the discharged environment to a level where ignition cannot occur. Carbon dioxide gas, which naturally occurs in the atmosphere and does not harm the ozone layer, has zero greenhouse effect and no conductivity, is also colorless and odorless.

It is the most effective solution especially in areas containing chemicals, enclosed spaces with electrical energy, and in protecting equipment or objects such as solvent processing sections of printing machines in the packaging industry. It leaves no residue after discharge, requires no cleaning, and protected systems or equipment can be restored to operation shortly after. Carbon dioxide suppression systems, which can be designed according to CEA 4007 NFPA 12 standards, can be designed as total flooding or local application systems.

When smoke, heat, or flame is detected by the system’s detectors, the carbon dioxide suppression system activates automatically or manually. The system discharge time is 60 seconds for Class A surface fires, and it has single or multiple cylinder mechanisms. The gas, which has very low refill costs, can be easily obtained. The gas, which is not in the clean agent class, should not be used in rooms containing delicate electrical and electronic devices or in continuously occupied areas due to its asphyxiating effect.
