A fire requires three elements to continue burning: oxygen, fuel, and heat. By eliminating any one of these, a fire can be suppressed or extinguished. While some suppression agents reduce the heat of a fire, a CO2 fire suppression system eliminates oxygen to suppress the fire. When the system detects smoke or fire, it releases the CO2 agent into the protected space. The CO2 level rises rapidly as the oxygen level drops, causing the fire to be suppressed or extinguished.

CO2 is a colorless, odorless, and electrically non-conductive gas that leaves no residue behind. Sensitive equipment within the protected space is therefore not damaged by the CO2, which reduces downtime and costs. Once CO2 has dispersed to safe levels, personnel can assess any fire or smoke damage and quickly resume work with no cleanup required.

The pipe network type of CO2 automatic fire suppression system is mainly composed of three parts: extinguishing devices, pipe fittings, and electrical accessories.

• Extinguishing devices — components such as the cylinder used to fill and store CO2, the frame, and the driving device (nitrogen cylinder) that triggers the storage cylinder to discharge the agent.
• Pipe fittings — conduits that connect the extinguishing device and guide the agent into the protected zone, such as high-pressure galvanized steel pipe, flanges, and elbows.
• Electrical accessories — devices used to detect and monitor the entire protected area and control the whole system, as well as to warn people to evacuate and prevent fire expansion.

These three integrated parts work together to efficiently detect, supervise, alarm, and automatically extinguish fire.

Suitable for protecting spaces such as libraries and archives rooms, electronic computer rooms, electrical substations, telecommunication rooms, hangars, garages, marine engine rooms, cargo holds, paint-spraying rooms, boiler rooms, and control centers.

The system is suitable for extinguishing all types of fires involving flammable liquids and solid matter, as well as gas fires in which power can be cut off before extinguishing the fire.
