Carbon Dioxide Fire Extinguishing System is a powerful fixed fire suppression solution widely used in marine vessels and industrial applications. Designed for total flooding fire protection, this system releases CO2 gas in bulk into an enclosed space, effectively displacing oxygen and extinguishing the fire without damaging equipment or leaving residue.
This CO2 flooding system is particularly suitable for high-risk, enclosed areas where rapid fire suppression is critical. These areas include:
- Ship engine rooms
- Cargo holds
- Purifier rooms
- Pump rooms
- Electrical cabinets and industrial enclosures
Product Description and Technical Specifications
The central bank CO2 fire extinguishing system stores carbon dioxide in high-pressure cylinders and releases it into the protected area through a distribution pipe network.
Key Specifications:
- System Type: High Pressure (HP) CO2 Fire Suppression System
- Driving Pressure: 6 MPa
- Design Pressure: 12.5 MPa
- Starting Gas Source: Nitrogen (N₂)
- Gas Discharge Time: 60 seconds (complete flooding)
- Actuation Mode: Manual, automatic, or remote electric start
- Installation: Fixed suppression system with central storage (banked CO2 cylinders)
How the CO2 Fire Extinguishing System Works
The CO2 fire suppression system operates by rapidly releasing carbon dioxide gas into a fire-affected space. The process is as follows:
- Fire is detected by a fire alarm or detection system.
- The system is manually or automatically activated using a control panel or emergency station.
- Nitrogen gas (N₂) acts as the starting source to drive the release valves.
- CO2 gas is discharged under high pressure (6 MPa) into the protected zone within 60 seconds.
- The oxygen level drops, suffocating the fire and bringing it under control or extinguishing it entirely.
This method ensures quick, efficient fire suppression without water, foam, or powder—ideal for protecting delicate machinery and electronics.
Benefits of a CO2 Fire Suppression System
- Fast and effective fire suppression
- Non-damaging to sensitive equipment – no residue or clean-up
- No electrical conductivity – safe for energized equipment
- Ideal for total flooding of enclosed spaces
- High reliability with automatic and manual release options
- Long-lasting CO2 gas cylinders with minimal maintenance
Applications
The CO2 fire extinguishing system is widely used across various marine and industrial environments:
- Marine vessels: cargo ships, oil tankers, engine rooms
- Power generation: transformer rooms, turbine enclosures
- Manufacturing and process industries
- Automated warehouses and data centers
- Paint booths and flammable liquid storage areas

Customization and Cylinder Capacity
Each CO2 extinguishing system can be customized based on:
- Protected volume size
- Discharge pressure requirements
- Cylinder quantity and layout
- Control and monitoring integrations
Cylinder capacities and storage configurations (vertical or horizontal) are available based on project specifications. Optional accessories include nozzles, pressure switches, actuators, control panels, and alarm systems.
Conclusion
The Carbon Dioxide Fire Extinguishing System is a proven, highly effective fire protection solution for spaces where water or chemical suppression agents are not suitable. Whether for ships, industrial plants, or hazardous zones, a CO2 fire suppression system offers clean, fast, and complete fire control.
