EGSA Founder Member Dürr Universal recommends a number of products for the silencing of internal combustion engine exhausts and air vacuum discharges. These utilise the original “straight through” absorptive principle, with exhaust pulse noise being effectively dissipated by absorptive material. This design provides very low restriction to exhaust gases, so the back pressure is negligible. Silencers of this type may also be used as secondary units on systems using reactive primary silencers.
Also available from Dürr Universal are:
*VENT SILENCERS: Gas compression station blowdowns are unbearably loud without the right acoustical treatments. Dürr Universal designs and manufactures vent silencers for this specific application across power generation and industrial processes, including the oil and gas industries. Our acoustics, flow management and structural design expertise lets you control the noise, blowdown and stack height. Via our supply chain options in the UK, Europe and India, we provide painted, galvanized and stainless-steel options that utilize in-house, qualified welding and non-destructive examination capabilities. Dürr Universal keeps your operation clean, quiet and safe.
*EXHAUST SILENCERS: Dürr Universal offers a wide range of exhaust silencers for industrial and marine diesel, gas and petroleum applications. These multi-chamber combination silencers often have a primary reactive chamber with absorptive secondary and are especially effective at a broad range of sound attenuations across both high and low frequencies. The designs are continually assessed to ensure high sound attenuation performance in a competitive market.
Dürr Universal owns Quietshield – a line of combination silencers developed to optimise the level of attenuation, silencer size and backpressure. Designed for engine and compressor applications that require high-quality, durable sound attenuation, the silencers have a high-performance internal design that delivers superior sound reduction.
The range of exhaust silencers can be used in isolation, in conjunction or integrated with other Dürr Universal silencers to produce the optimum acoustic solution.
*SPARK ARRESTOR SILENCERS: Dürr Universal offers a wide range of DNV-approved spark arrestor silencers for use in hazardous environments. The designs provide excellent low- and broad-band frequency attenuation for industrial and marine applications, as well as options for fire precautions. The unique design allows dangerous sparks to be removed from the exhaust gas and provides an attenuation range up to 45dB. The hot particles are trapped safely within the arrestor dust box for removal later. The range of spark arrestor silencers can be used in isolation, in conjunction or integrated with other Dürr Universal silencers to produce the ideal acoustic solution.
In addition to the silencers, Dürr Universal supplies equipment for full inlet and exhaust lines including pipework, bellows, and structural steel - in effect this represents the whole silencer system, with the silencers mentioned here forming the range available. Dürr Ltd. Clean Technology Systems, CTS Universal, is based at Barleyfield, Hinckley, LE101YE, United Kingdom.
