ACOUSTIC ATTENUATORS – LOUVERS – SILENCERS

Acoustic Attenuators – Louvers – Silencers

ECOTONE™ acoustic attenuators are us full to reduce noise generated by air or gas flow with keeping the pressure drop as low as possible without compromising the air or gas flow itself , acoustic attenuators or silencers are commonly used in , industrial, power plants , steel plants or mixed applications.

ECOTONE™ offers a complete range of acoustic attenuators / noise silencers to meet noise pollution control requirement. Ready-made silencers and custom built solutions are offered as per site requirements.

ECOTONE™ provide acoustic attenuators for HVAC systems, Industrial fan n inlets and discharge at radiators, cooling towers, generators noise .

ECOTONE™ provides different type of acoustic attenuators depending on the design or construction of attenuators of a specific application. For example circular type / rectangular attenuators depending on the type of the inlets or outlets of the system. other type of acoustic attenuators are bend attenuators, called cross-talk attenuators, air-relief silencers, cross-talk attenuators etc.

Selection of Acoustic Attenuators are depends several factors, such as type of equipment, location of silencer , shape of pipelines , indoor, outdoor, increased humidity , affordable pressure drop. ECOTONE™ experts can help you with choosing an acoustic attenuator among those available in standard dimensions
