MINNEAPOLIS - CUMMINS POWER GENERATION has found a wait to quiet its Tier 3 generator sets with advanced sound-attenuation enclosures. The 100-kW version has a sound level of only 67.5 dB(A), one of the industry's quietest. The same technology is also applied to 125- and 150-kW Tier 3 generator sets.
Generators can be ordered in steel or aluminum enclosures with either of two levels of sound attenuation. The extreme low-noise levels are achieved in part by forcing the cooling air to make two 90-degree bends, thus reducing high-frequency sound. The enclosures also have convenient access doors for access to the engine and alternator.
