CO2 Nozzle Spacing
CO2 Nozzle Spacing
(OP)
Hello.
I need some help on Carbon Dioxide system. I am wondering how the area coverage for nozzles should be considered in designing 1)Total Flooding and 2)Local Application in comparison with maximum sprinkler head spacings in water-baed system(NFPA 13). Any input would be greatly appreciated...

RE: CO2 Nozzle Spacing
For total flooding applications distribute the discharge nozzles based upon the following two constraints:
i- Maximum Spacing = 20 ft (6 m)
ii- Flow Rate, based on Table below:
Nozzle Size (in.) Flow Rate per Nozzle (lb/min)
½ Up to 120
¾ 121 – 250
But please keep in mind that these values are for guidance only, and should be confirmed by proper hydraulic calculations.
Regards.
