 Sound Attenuation Packages
The standard LRW is the quietest, low silhouette, centrifugal fan, closed circuit cooler in the industry. This is achieved by providing the first stage of inlet sound attenuation as part of the LRW's standard design. The LRW drive system, including the fan housing(s), electric motors, belts, bearings and drives, is completely enclosed by a protective housing providing a significant level of sound reduction.
If the standard LRW sound pressure level is not quiet enough for certain applications, the should 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 EVAPCO, Inc. for Factory Certified Sound Data for each option.
