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.
