Carbon Dioxide (CO2)

Carbon dioxide (CO2) is colorless, odorless, and electrically non-conductive. It is characterized by rapid and effective penetration into the protected area, making it the most commonly used gaseous extinguishing agent in firefighting equipment. Years of accumulated experience facilitate engineering in a myriad of applications related to CO2 automatic extinguishing systems.

Two physical principles fundamentally govern the extinguishing mechanisms of carbon dioxide.

The first allows oxygen concentration to be reduced below 15% (a lower concentration prevents most fires that cannot sustain combustion). The second mechanism relies on cooling and heat absorption from the protected area.

CO2 automatic extinguishing requires precise safety measures in occupied areas to ensure the protection of personnel. Indeed, even at low concentrations, it can cause suffocation.
