O Gas has the following advantages:
– Fast and efficient extinguishing due to the oxygen depletion combined with cool-
ing effect
– Reliably avoids re-ignition, typical in deep seated fires
– Excellent property protection due to minimal water use: Droplet spectrum and
water fog can be designed for an optimum cooling effect
– Cost savings through shared piping network and nozzles for water and nitrogen
– Increased safety for people through the reduction of toxic fumes
– Precisely tailored to customer needs thanks to special system design software

O Gas requires smaller overpressure flap openings. As part
of the nitrogen is used to propel the water, there is a resulting softened initial burst
of gas, which turns into less required overpressure openings and thus lower costs.
