Data Centres 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. Inert gas fire suppression systems, normally used to protect this type of equipment, can produce sound levels that may have adverse effects on noise sensitive equipment. The ANSUL® Acoustic Nozzle, designed for inert gas fire suppression systems, decreases the acoustic footprint during a discharge. The Nozzle directs the agent into the hazard area and reduces the sound level. Flow calculations are used to specify the nozzle orifice size for the correct quantity and distribution of agent.
The ANSUL acoustic nozzle is scientifically proven and supports the claims of Johnson Controls that it can reduce sound levels the may affect sensitive IT equipment, especially hard drives. Earning the product UL verification (Independent Science based assessment), a first in the fire protection industry.
The ANSUL Acoustic Nozzle, in combination with the INERGEN® 150/200 Bar and INERGEN® 300 Bar with iFLOW Technology Fire Suppression Systems, is particularly useful for suppressing fires in hazards where sound levels may affect sensitive electronic equipment. Typical applications for the Acoustic Nozzle include server rooms and data centres.

The ANSUL Acoustic Nozzle directs agent into the hazard area and reduces the sound level compared with standard nozzles. Flow calculations are used to specify the nozzle orifice size for the correct quantity and distribution of agent. This game-changing product is UL Listed with INERGEN 150, 200 and 300-bar fire suppression systems and replaces the standard INERGEN nozzle without major pipe rework or hydraulic adjustments, making it an affordable solution for retrofits.
