Sound attenuation

HFL cooling towers use quiet centrifugal fans, but to reduce noise even further, you can extend your HFL cooling tower with sound attenuators at the air intake and discharge points.

For residential areas:

Sound attenuation (HS type)

  • Discharge attenuator with vertical baffles
  • Intake attenuator with straight baffles

For rural areas:

Heavy sound attenuation (HD type)

  • Discharge attenuator with vertical baffles
  • Double intake attenuator with straight baffles

Your local BAC representative can explain any of the above sound attenuator options in more detail and provide you with sound pressure and sound power data.
