CO2-System

CO2 - System

Why CO2 ?

• Electrically non-conductive gas.
• Environmentally friendly.
• Natural occurring gas.
• Well specified -NFPA 12.
• Leaves no residue.
• Available refill at low cost.

what is CO2 ?

• Carbon Dioxide.
• Colorless and odorless gas.
• Clean agent substitute to Halon 1301.
• Pressurized at 57 bars in high pressure cylinders at liquid state.
• Density is 50% greater than air.

Where to use CO2 ?

• Unoccupied areas of electronic and technical rooms.
• Transformer Rooms.
• Battery and UPS Rooms.
• Remote base stations and shelters.
• Archive and storage Rooms.
• Generator room and power House.
• Flammable liquid materials.
• Fuel Room.

How dose CO2 work ?

• Liquid CO2 forms solid dry ice (snow) when released into the atmosphere - cooling and heat absorption effect.
• CO2 reduces the concentrations of oxygen in the air to the point where combustion stops - from 21 to below 15%.
• Consideration must be given to the fact that if CO2 is inhaled, it may lead to asphyxia.

CO2 System Operation :

• Fire detectors sense fire conditions in the hazard area (smoke,heat,gas,air sampling...)
• Electrical signal is sent through the fire alarm alarm control panel FACP to the control head.
• Control head releases CO2 from the cylinders and is delivered through a fixed piping network to discharge nozzles in 1 min for surface fires and less than 7 min for deep-seated fire.

Methods of Application 

Three methods of application :

• Total flooding for enclosed spaces.
• Local application for discharge directly into the fire (surface fire in flammable liquid,gases..).
• Hand hose line for fixed supply of CO2.
