Engine Exhaust Silencers

The Dürr Universal team has more than 60 years of experience engineering and manufacturing industrial engine exhaust silencers, including both diesel engine exhaust silencers and natural gas engine exhaust silencers. Applications include power generation, gas compression, engine test cells, marine (propulsion and generators), and locomotive.

Silencers for engine exhaust applications

Dürr Universal’s manufacturing and engineering teams deliver world class primary industrial silencers and secondary industrial silencers to reduce noise for many different engine product lines. Silencers are available with acoustic performance ranging from industrial to ultra-quiet attenuation grades. Dürr Universal's engine exhaust silencers are offered in a variety of styles and configurations, including cylindrical, puck and oval configurations. Engine exhaust silencers can also be designed to include emission reduction, spark arresting or pressure-relief capabilities.

Dürr Universal offers a comprehensive range of high-quality, fully welded:

  • Absorptive engine exhaust silencers
  • Reactive engine exhaust silencers
  • DNV-approved spark arrestor engine exhaust silencers
  • Combination engine exhaust silencers

Dürr Universal produces diesel engine exhaust silencers, as well as gas internal combustion engine silencers. Each engine and operating location require a unique combination of silencer properties to achieve the specific acoustic goal. For this reason, many different silencer models are available. In cases where standard silencers will not meet a particular requirement, custom (bespoke) engine exhaust silencers can be designed to satisfy the most challenging customer requirements.

Most naturally aspirated and turbocharged engines need a multi-chamber engine exhaust silencer. Many super-charged engines are best silenced with this design. Some applications may also use a straight-through design, in which low backpressure is required.

Dürr Universal offers a wide range of both stationary genset exhaust silencers and mobile genset exhaust silencers for fixed- and variable-speed engines (low, medium and high-speed RPM).

A full line of engine exhaust accessories is also available including, insulation blankets, expansion joints, exhaust piping/connectors, rain caps and support brackets.
