LoTec, Inc. designed, fabricated, and directed the manufacture of eight identical stainless-steel Solar Saturn exhaust silencers — reactive silencers — for a single building. The requirement was 45 dBA at 190 meters, including self-generation and breakout noise, and a pressure drop of 1.10 inches water column.

45 dBA at 190 meters — about the sound of birds.

The requirement

Eight identical units in one building is uncommon. Most of the spec was straightforward. The noise number was not. That 45 dBA target was only possible because of how remote the site was.

What LoTec did

LoTec verified the requirements, monitored the design, and directed manufacturing of the components, with particular attention to cutting self-generated noise.

After

The customer was satisfied with both the performance of the silencers and the schedule. That work led to additional packages: more reactive silencers, and combination reactive/absorbing silencers.

LoTec has designed, fabricated, and installed turbine exhaust silencers and related low-noise systems for over 30 years. If you are specifying this work, we can look at the environment and the machine together.
