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.

I have been involved in the design of numerous fire sprinkler systems over my 40 years in the industry and it all starts with the water supply. best garden sprinkler
