The ANSUL Acoustic Nozzle is designed for inert gas fire suppression systems used in sensitive environments such as data centers and server rooms. It helps reduce sound levels during system discharge, protecting noise-sensitive equipment like hard disk drives while effectively directing the fire suppression agent into the hazard area.
Built with durable materials and a 360-degree discharge pattern, the nozzle improves fire protection performance while minimizing acoustic impact on critical electronic equipment.
The ANSUL® Acoustic Nozzle is designed for use in inert gas fire suppression systems to help protect sensitive environments such as data centers and server rooms. Modern computing equipment, particularly hard disk drives (HDDs), can be affected by high sound levels generated during fire suppression system discharges. The Acoustic Nozzle helps reduce the acoustic footprint during discharge, minimizing the risk of damage to noise-sensitive electronic equipment while still delivering effective fire suppression.
The nozzle directs the suppression agent evenly into the hazard area with a 360-degree discharge pattern, ensuring proper distribution while reducing sound levels compared to standard nozzles. It is specifically designed to work with INERGEN® 150/200 bar and iFLOW 300 bar fire suppression systems, making it well suited for protecting critical IT infrastructure and high-value electronic assets.
Constructed with an aluminum body and sound-damping materials, the Acoustic Nozzle combines durability with acoustic performance. It helps control sound pressure levels that could otherwise impact equipment performance during a system discharge. When combined with proper nozzle placement and room acoustic treatments, it can further reduce noise impact and improve overall system effectiveness.
Overall, the ANSUL Acoustic Nozzle provides effective fire suppression agent distribution while reducing discharge noise, making it an ideal solution for facilities where both fire protection and protection of sensitive electronic equipment are critical.
FSP Can Supply Ansul Inergen Acoustic Discharge Nozzle IG-541 New & Replacement (445710). The Ansul and Hygood Accoustic Nozzles are designed to decrease the acoustic footprint of Inergen agent during a discharge.
With Data Centres providing more and more essential services, Inergen Gas Suppression systems are being increasing utilised in these applications. With the data being stored on higher capacity disks, these disks become more suseptable to vibration and movement, such as the interference by sound power and sound pressure.
Data center operators should be reviewing acoustics within their facilities and the Fire Suppression systems should form a part of this review.
