Gas extinguishing system

A gas extinguishing system for a predefined protected area, wherein the gas extinguishing system comprises:

• an inert gas source, designed to provide inert gas at least during a flooding period dimensioned for the protected area;
• and
• a diffuser system fluidly connected or connectable to the inert gas source by a tubing system, wherein the diffuser system includes:
• at least one diffuser tube having a plurality of drill holes provided in a surface of the diffuser tube through which at least a portion of the inert gas provided by the inert gas source is introduced radially into the protected area relative to a longitudinal direction of the diffuser tube;
• and
• a pressure reducer allocated to the at least one diffuser tube including a baffle, wherein the pressure reducer is fluidly disposed between the tubing system and the at least one diffuser tube and separates the tubing system, which is at a maximum of 60 bar, from the diffuser tube defining a low-pressure area relative to the tubing system,
• the diffuser system operating with a primary baffle pressure, associated with the baffle, measured in absolute bar that is at least twice as high as an internal pressure of the diffuser tube during the flooding period, and the diffuser system operating with the internal pressure of the diffuser tube during the flooding period amounts to a maximum of 2 bar absolute.
