The low sound levels generated by BAC products make them suitable for installation in most environments. Although axial fan units such as the Series 3000, Series 1500, PT2 Cooling Towers can meet the sound requirements of most installations, centrifugal fan models such as the VT1 and VTL should be considered for extremely sound sensitive installations.

To evaluate whether an axial fan unit can be applied on a particular application, follow these steps to minimize the impact of sound on the environment. These suggestions are ordered with regard to the impact they will have on cost.

  • Provide a method of capacity control. Capacity control will allow the fan to run at lower speeds when loads are lighter or the wet-bulb is lower. These lower speeds are often sufficient to provide the scheduled capacity at night, when sound requirements are the most stringent.
  • For PT2 models, a low sound fan option may be available to significantly reduce the sound levels generated from the unit.
  • Factory designed, tested and rated sound attenuation is available on the discharge for further sound attenuation.
  • Barrier walls can be constructed to prevent sound transmission to sensitive areas.
