Data Centre Server Chiller Farm – £100k wasted on noise control

data center server farm fan noise attenuation

Data centres require a lot of cooling - which involves noisy chiller fans, air handling units and condensers. Moreover, in addition to the general fan air noise, there are often low-frequency tonal elements (hums) that cannot be silenced using conventional silencers and acoustic barriers. Fortunately, there are low-cost alternatives...

An Abatement Notice was issued re the noise from a large array of chillers and air handling units at this data centre. The company had already spent nearly £100k on noise control with very little success and were considering claiming Best Practicable means (BPM) in court when the council suggested they might like to get a second opinion from us…

Our accurate diagnosis and control technology meant that we could guarantee BPM would be implemented by recommending a range of innovative noise reduction techniques for the AHUs and chiller condenser fans. These reduced the plant noise by 15dB at less than half the previously expected cost. If this approach had been implemented in the first place, the company would have saved over £100k, the council would have saved resources and the complainants would not have had to suffer unnecessary disturbance over a 2 year period.
