The system of any one of claims 25 and 27, wherein the sound power level from the nozzle is no greater than dB. Ep: the epo has been informed by wipo that ep was designated in this application. The nozzle includes an inlet that connects to the distribution piping and includes a plurality of outlet holes. The low midrange contains the low order harmonics of most instruments and is generally viewed as the bass presence range. The second outer annular ring ' is comprised of a support platea hoopand a sound absorbing insert In other words, the radially facing primary apertures extend transversely through the sidewall of the inner tube

    The rows can be parallel to each other.

    The sound absorbing rings reduce the interaction between the gas flow and the outer tube Depending on the configuration of the enclosure being protected, the pressure reducing device reduces the pressure to achieve the required inert gas flow for the enclosure.

    The remaining structure of annular ring ' is similar to annular ring discussed above and thus, for brevity, will be omitted. To accomplish this, typically, the inert gas suppression systems often discharge the inert gas at supersonic velocities. Nozzle also includes a second set of secondary outlets that includes a plurality of radially facing apertures As it exits the first secondary outletsthe first fluid flow portion Fl is directed between sound absorbing surfaces and of inserts andrespectively, which further reduce the sound.

    Thus, while electronic equipment in an enclosure may be unaffected by the fire itself, the equipment can still experience damage and thus downtime due to the high sound levels from the inert gas discharge.

    The stainless steel wool can be, e. Depending on the system, the high pressure source can be connected to more than one enclosure, through pipe network ending in multiple nozzles, and the flow to each enclosure is individually controlled via respective control valves.

    Similarly, as it exits the second secondary outletsthe second fluid flow portion F2 is directed between sound absorbing surfaces and of inserts andrespectively, which further reduce the sound. In embodiments that use inner ring see FIG. The system of any one of claims andwherein a sound power level of the nozzle is in a range between dB to dB for inert gas flow rates in a range of approximately CFM to approximately 5, CFM.

    Detailed Description [ Exemplary embodiments of the present disclosure are directed to inert gas nozzles that suppress the sound from the nozzles to acceptable levels without the high pressure drop in the nozzle as found in prior art and related art systems.
