 Sound Attenuation
If the standard LRW sound pressure level is not quiet enough for certain applications, the sound levels can be further reduced by adding various stages of sound attenuation. The sound attenuation options of the LRW can be provided in stages and will provide varying degrees of attenuation based on the stage of attenuation selected. Consult the factory for Factory Certified Sound Data for each option.
Fan Side Inlet Attenuation
Reduces sound radiated from the fan side air intakes and has an open bottom to allow for air entry. This attenuation package ships loose to be mounted in the field on each side of the cooling tower over the fan intakes.
Fan End Inlet Attenuation
Reduces sound radiated through the far end air intake. It consists of baffled panels to change the path of the air entry and to capture the radiated noise thus reducing the overall sound levels generated. In addition, the external belt adjustment mechanism is extended through the inlet attenuator to allow easy belt adjustment without having to enter the unit.
Discharge Attenuation
The discharge attenuation hood features a straight sided design with insulated baffles to reduce the overall sound levels of the discharge air. The discharge attenuation incorporates a large access panel to allow entry to the drift eliminators and water distribution system. If a higher discharge velocity is required, a tapered discharge hood providing minimal sound attenuation is available.
