A new series of 100-, 125-, and 150-kW Environmental Protection Agency Tier 3 generator sets with advanced sound-attenuated enclosure systems is available. The series comes in steel or aluminum with two levels of sound attenuation. The generator set and enclosure packages are intended for all-weather outdoor use wherever local ordinances or circumstances require sound abatement. The quieter sound-attenuation package features an enhanced exhaust silencer and steel construction with sound-absorbing material. This limits sound levels to 67.5 dBa for the 100-kW generator set package; 68.6 dBa for the 125-kW generator set package; and 69.6 dBa for the 150-kW generator set package (measured at 23 feet [7 meters] with the generator set operating at full rated load). Weather-protective generator set enclosures are also available. The package includes an industrial exhaust silencer and 14-gauge steel construction without added sound-absorbing features.
