Carbon Dioxide (CO2) Karbondioksit Gazlı Söndürme Sistemleri
Historically most renowned and researched fire suppression agent, making it highly customizable according to the hazard being protected. Even though it is not ideal for human occupied spaces (mandatory safety precautions must be taken if people are present), it is the most effective gas for the suppression of a wide range of fires, Class A, B and C.
- Colourless and odourless
- Chemically inert
- Electrically non conductive
- No residues upon discharge
- Easily refilled locally
- Low cost for unoccupied areas
Fire suppression mechanism
- Displacing oxygen content in the atmosphere, reducing oxygen concentration from 21% to 15% (for most applications).
- Cooling effect by removing sufficient heat from the fire.
Methods of application
- Total flooding application: consists in discharging a certain amount of carbon dioxide into a fixed enclosure up to prescribed concentration.
- Local application: when the burning hazard is relatively smaller compared to the volume of the enclosure, it is more effective to discharge the CO2 directly to the surface-type fires and potential deep-seated fire.
Typical hazards protected
Including but not limited to:
- Marine industries: engine rooms, paint lockers, vehicle transport areas on cargo vessels, flammable liquid storage areas.
- Heavy industries: rolling mill, control rooms, sheet printing, particle board chippers, cable trays, electrical room, motor control centres, nuclear power facilities, waste storage facilities, etc.
Complete High Pressure systems (57 bar @ 20 ºC) using 67 litre cylinders with all the necessary components, all that is missing is the piping and the installation. Depending on the risk(s) being protected, various configurations can be designed:
- Modular systems (one cylinder configuration)
- Bank systems (multiple cylinder configuration)
- Selector valve systems (one system configured to protect various risks)
Check out its key features:
- Compact valve technology: allows using the standard cylinder transportation safety cap, avoids using special caps and adapters.
- Direct release circuit: outlet connection to activate the slave cylinders from the master valve, eliminating the pilot cylinder and relief screw (except selector valve configuration).
- Maintenance at its safest: all components may be assembled and disassembled whilst under pressure, this includes: pressure gauge, pneumatic release, manual release and solenoid valve.
- Discharge-free commissioning system: whilst performing system functional testing during commissioning, the release circuit can be disconnected from the valves avoiding any accidental discharge and allow easy testing.
- Standing strong and secure: stand alone or wall mounted brackets with several configurations available, adapting the system to the room space.
- Flexible and resistant: all release and discharge hoses take into account the best balance between flexibility and durability, allowing easy installation and strength to withstand the pass of time.
- Spare-parts free: upon discharge or during maintenance, no rupture disks, nor special components must be replaced. Reducing down-time and lowering warehousing costs.
- Differential pressure actuation: allows using the same pressure from the cylinder to maintain the valve closed, reducing dramatically leakage problems even with high temperature fluctuations.
- Optimized standardization of systems: common components between systems reduces quantities needed hence saving on warehousing costs and allowing fast delivery to clients locally.
