CO₂ gas firefighting systems

CO₂ (carbon dioxide) fire protection systems represent an efficient and versatile solution for protecting a variety of environments from different types of fires, offering significant advantages in terms of safety and performance.

Their operating principle is based on the use of carbon dioxide as a gaseous extinguishing agent, which can remove oxygen and quickly and safely stop the combustion process.

Functionality and extinguishing principles

CO₂ fire protection systems operate by discharging carbon dioxide in gaseous form into the area at risk of fire. Carbon dioxide acts on two main fronts:

1. Smothering: CO₂ reduces the oxygen concentration in the environment (down to levels between 14% and 5%) below the minimum required to sustain combustion, quickly extinguishing the fire.
2. Cooling: Carbon dioxide removes heat from the fire and incandescent materials, helping lower the temperature and hinder the spread of flames.

The effectiveness of CO₂ systems comes from the combination of these two mechanisms, making them particularly suitable for extinguishing Class B (flammable liquids) and Class C (combustible gases) fires. In total saturation, the extinguishing action can also be effective on Class A fires (combustible solid materials).

• High extinguishing effectiveness: CO₂ is a versatile and powerful extinguishing agent capable of quickly smothering a wide range of fires.
• Clean action: CO₂ leaves no harmful residues, avoiding damage to machinery, equipment and valuable materials.
• Non-toxic: CO₂ is a non-toxic gas.
• Electrical safety: CO₂ is an inert gas and does not conduct electricity, making it ideal for protecting electrical equipment and environments at risk of explosions.

• Wide adaptability: CO₂ systems can be installed in a variety of environments, both for total saturation and localized protection.
• Penetration in hard-to-reach areas: Since it is a gas, carbon dioxide easily spreads even in hard-to-reach areas that are inaccessible to other extinguishing systems.
• Compatible with other safety systems: It can be integrated with other fire protection systems, such as fire detection and alarm systems, for greater effectiveness in emergency management.

Transformer rooms and electrical panels

Protecting transformer rooms and electrical panels is crucial to ensure operational continuity and prevent significant economic damage. CO₂ fire suppression systems are particularly suitable for these environments as they leave no harmful residue and do not interfere with electrical or electronic components.

Printing presses

The presence of paper material combined with synthetic inks and cellulose powders from processing requires extremely fast and effective fire extinguishing systems. CO₂ firefighting systems offer reliable protection for this type of machinery, safeguarding production facilities and materials.

Flammable transfer rooms

The presence of flammable liquids, combustible gases and hazardous materials requires highly effective and safe extinguishing systems. CO₂ fire suppression systems provide optimal protection in these environments, preventing explosive fires and safeguarding the health of workers.
