Carbon dioxide (CO2), which has been used in the suppression systems since the early 1900s, is the oldest and the most commonly used suppression gas. When it is discharged, it prevents fire by reducing the oxygen ratio to a point where ignition will not occur. CO2 gas, which is naturally found in the atmosphere, does not harm the ozone, has zero greenhouse effect, has no conductivity and is also colorless and odorless.
It is the most effective solution for the protection of equipment or items such as solvent-treated parts of printing machines, particularly in the areas where chemicals are present, as well as in enclosed areas where electrical energy is present, and in the packaging sector. It leaves no residues after discharge, does not require cleaning, and fire-protected systems or equipment can be re-activated in a short period of time.
CO2 extinguishing systems, which can be designed in accordance with the CEA 4007 & NFPA 12 standards, can be designed as both in-room and local suppression applications. System discharge time is 60 seconds for Class A surface fires. Systems can be single or multi-cylinders. CO2 gas, which has quite low costs of refilling, can be easily supplied.
Use of CO2, which is not listed as a clean gas, is not suitable in rooms with delicate electrical and electronic equipment due to its cooling effect, and in b locations where people are continuously present, due to its suffocating effect.
