The following series of photos depicts a Supper Quiet Robinson Custom Enclosure being installed in a Collier County, FL, wellfield. Since the unit was required to reduce noice to no more than 60 dBA at one meter, Robinson designed a custom enclosure capability of reducing the source noise by 40 dBA. That is why this unique Cummins Power South 450 KW unit has "Penthouses" on both ends of the enclosure roof. Inside these penthouses are specially designed sound attenuation baffles that keep the noice down to specification requirements while still allowing the flow of air in and out of the structure. The customer and installation contractor are extremely impresseed with how quiet the unit is at full load.
