CO2 Suppression Systems
Total-Flooding CO2 Suppression Systems use carbon dioxide at high concentration (34-62% depending on fuel) to extinguish fires by oxygen displacement. They differ fundamentally from clean-agent systems by being hazardous to people and requiring mandatory evacuation before discharge. Designed for unoccupied areas and specific high-risk equipment.

About this category
CO2 suppression systems are among the oldest automatic gas systems and are still used in specific applications where alternatives are not viable. The design: high-pressure CO2 cylinders (50-70 bar) or low-pressure refrigerated storage (20 bar at -18°C), tight steel piping, distributed discharge nozzles, an independent fire-detection system, pre-discharge evacuation alarms, and a pneumatic safety lockout. Design concentration varies: around 34% for ordinary liquids, 50-62% for special fuels. Operating sequence: detection → audible/visual alarm → 30-60 s evacuation delay → CO2 discharge within one minute → holding concentration for 10-20 minutes. Applications: unoccupied generator rooms, transformer vaults, industrial battery rooms, printing and paint facilities, flammable-liquid storage, and manufacturing cells. A key advantage: high effectiveness on liquids and electrical, lower cost than clean agents, no residue. A substantive difference from FM-200 and Novec 1230: CO2 works by oxygen displacement (asphyxiation risk); clean agents work by heat absorption and chemical inhibition (used in occupied spaces only within design concentration and approved exposure limits). A critical technical note: total-flooding CO2 is prohibited in occupied areas due to the risk of death by asphyxiation; clear warning signage, personnel-entry lockout, and a documented evacuation plan are mandatory. Design, installation, and maintenance reference frameworks vary by model, application, and local requirements, so product and project documentation should be reviewed before procurement.
