AURA industrial silencers reduce noise generated in piping systems and industrial installations where steam or gases flow, expand or are discharged. High flow velocities and pressure differences can generate significant noise levels. Suitable silencers help reduce sound emissions and improve noise conditions in industrial environments. AURA designs and manufactures customized absorption and throttling silencers for demanding industrial applications. Each silencer is engineered according to the operating medium, temperature, pressure, flow conditions and required noise reduction. As a specialist in industrial process heat, AURA has extensive experience with the technical requirements of industrial thermal and fluid systems. This expertise also supports the design of our industrial silencers.
Operating media: Steam and gas
Maximum operating temperature: Up to 550°C
Nominal pipe sizes: DN 20 to DN 300
Silencer types: Absorption and throttling silencers
System design: Customized according to operating conditions
The specific design depends on the operating medium, temperature, pressure, flow rate and acoustic requirements.
Absorption silencers:
Absorption silencers reduce the transmission of airborne noise in industrial piping systems and installations. Typical designs include inline silencers and splitter silencers. They are used, for example, when steam or gases are drawn in or discharged and generate significant flow noise. Absorption silencers are particularly suitable for reducing airborne noise in the medium-frequency range. The actual attenuation depends on the design and frequency spectrum.
Throttling silencers:
Throttling silencers are used when pressurized steam or gases are expanded or discharged. They combine controlled pressure reduction with measures to reduce the resulting noise emissions. Typical applications include pressure vessels, autoclaves and industrial piping systems. The appropriate silencer design depends on operating pressure, temperature, flow rate and acoustic requirements.
AURA industrial silencers can be used in various industrial installations, including:
