DATA SHEET SAPPHIRE® Acoustic Nozzles Description Data centers and server rooms are continuously improving their efficiencies to store and process more data. Improvements in computing hardware have led to an increase in Hard Disk Drive (HDD) sensitivity to sound. High pressure SAPPHIRE® systems, used to protect this type of equipment, can produce sound levels that may have adverse effects on noise-sensitive equipment. The ANSUL® Acoustic Nozzle is designed for SAPPHIRE PLUS and 42-Bar SAPPHIRE fire suppression systems and decreases the acoustic footprint during discharge while maximizing agent vaporization. The nozzle directs agent into the hazard area and reduces the sound level during discharge compared with standard nozzles. Flow calculations are used to specify the nozzle orifice size for the correct quantity and distribution of agent. Application The ANSUL® Acoustic Nozzle, in combination with the SAPPHIRE PLUS Fire Suppression Systems, is suitable for suppressing fires in hazard areas where sound levels may affect sensitive electronic equipment. Typical applications for the acoustic nozzle include server rooms and data centers.

NOZZLE DIMENSIONS Sound Performance Sound power is the amount of sound energy produced by a noise source such as a fire suppression system discharge nozzle. The ANSUL® Acoustic Nozzle is designed to reduce the sound power level produced during a discharge of the SAPPHIRE PLUS Fire Suppression System. Sound pressure is the sound received at a location remote from the noise source. The remote location may include HDDs. Sound pressure is the critical sound energy relevant to the effects on the...
