Carbon Dioxide CO2 Total Flooding Fire System is a highly effective fire suppression solution designed to quickly extinguish fires in enclosed or open areas. This advanced system operates in both total flooding and local application modes, offering flexible protection for a wide range of industrial and commercial environments.
In a total flooding mode, the system releases CO₂ gas to completely fill a sealed room, rapidly extinguishing the fire by reducing the oxygen level. In a local application mode, it targets non-deep-seated fires in open spaces or on specific equipment, making it ideal for areas where sealing is not possible.
How the Carbon Dioxide Fire Suppression System Works
The high-pressure CO₂ fire suppression system stores carbon dioxide in liquid form under pressure inside steel cylinders. When a fire occurs, the system activates and discharges CO₂ gas through a network of nozzles and hoses.
As the CO₂ is released, it expands rapidly, absorbing large amounts of heat from the surrounding area. This process reduces the temperature of the fire zone and lowers the oxygen concentration, effectively smothering the flames.
Because carbon dioxide is non-conductive and leaves no residue, it is ideal for protecting sensitive electronic equipment, machinery, and valuable assets without causing secondary damage.
However, CO₂ systems should only be used in unoccupied areas or in zones where safety precautions can be implemented, as high concentrations of carbon dioxide can cause asphyxiation.
Key Advantages of the CO₂ Total Flooding Fire System
- Rapid Fire Suppression: Extinguishes fires in 60 seconds or less, minimizing damage and downtime.
- Safe for Equipment: The CO₂ gas leaves no residue and does not harm electronics or sensitive components.
- Clear Visibility: Produces almost no visual obstruction, allowing for quick and safe evacuation.
- Eco-Friendly: CO₂ has zero ozone depletion potential, making it environmentally friendly.
- Compact Design: Requires minimal storage space and allows for easy installation.
- Low Maintenance: The system components are durable and require simple periodic inspection.
Main Components of the System
- Storage Cylinders: Contain high-pressure CO₂ with cylinder valves, solenoid valves, and dip tubes.
- High-Pressure Hose: Connects the cylinder valve to the liquid check valve, ensuring safe discharge.
- Discharge Nozzle: Installed at the end of the pipe network to release the CO₂ gas uniformly.
- Control System: Includes a control panel, smoke and heat detectors, fire alarms, and discharge indicators for complete system automation.

Applications of CO₂ Fire Suppression Systems
The CO₂ total flooding system is widely used across industries where fast and residue-free suppression is essential. Typical applications include:
- Power generation plants and electrical substations
- Data centers and server rooms
- Marine engine rooms and ship machinery spaces
- Manufacturing and chemical facilities
- Transformer and turbine enclosures
- Industrial kitchens and laboratories
Because of its fast response time and clean extinguishing properties, CO₂ fire systems are ideal for areas where other agents like water or foam may cause damage.
Safety Precautions
While CO₂ systems are efficient, safety remains a top priority. Since carbon dioxide can displace oxygen, personnel must evacuate the protected area before system discharge. It’s essential to include warning devices, delay timers, and manual release controls to ensure safe operation.
