Data Centre Safety/ Fire Suppression Innovation of the Year
Johnson Controls is proud to introduce an Acoustic Nozzle specifically designed to be used as part of the SAPPHIRE PLUS 70 bar system using Novec 1230 fire protection fluid. This solution joins the inert gas acoustic product introduced in 2017 and is fully implemented in the acoustic calculator, a unique tool designed to model the acoustic effects in the Data Centre environment.
Johnson Controls acoustic nozzles, when used with the proprietary acoustic calculator, provide the means to decrease the noise level (sound power) of a fire suppression system discharge in areas containing sensitive hard disk drives in Data Centres.
The noise output of the nozzle has been verified by UL, its area coverage confirmed to be identical to the standard area coverage of the non-acoustic nozzle, leading to a full UL approval.
Unlike other nozzles available in the market today, the Johnson Controls solution offers a complete package, using the calculation tool, which integrates the performance of the nozzle with the means to estimate the acoustic effects, when a system is discharged.
The calculation tool allows Johnson Controls to provide specific room modeling that takes into account the sound pressure generated by the nozzle, using the agent flow rate, distance from the hard disk drive and room construction.
As indicated the addition of the SAPPHIRE acoustic nozzle now forms a suite of products that transcends the decision of choosing either a halocarbon or inert gas, based only on the ability to provide an acoustic solution.
