Engine exhaust silencers SMP

The SMP range of engine exhaust silencers developed by Groupe BOËT has been designed to meet the growing challenges of noise reduction in industrial environments. These solutions cover a wide spectrum of acoustic performance, from standard attenuation to very high reductions, enabling them to adapt to the varied requirements of noise-sensitive operators and infrastructures. Thanks to a proven combination of reactive, multi-volume and absorptive systems, SMP silencers ensure long-lasting efficiency and preserved engine performance, even under the most demanding operating conditions.

Modular solutions for every acoustic requirement

The SMP range stands out for its flexibility and modularity, offering an optimized solution for every industrial project. This versatile range covers cogeneration and generator applications as well as projects in urban or hospital areas, where noise control is essential.

Entry-level models guarantee moderate noise reduction, ideal for sites with limited acoustic constraints.
Intermediate models offer a compromise between compactness, attenuation and engine efficiency.
High-performance models achieve attenuation levels of up to 48-50 dB(A), thanks to a multi-volume design with reactive and absorptive coupling, suitable for installations with stringent acoustic requirements.

Field of application

Power generation
Cogeneration plants
Stationary and mobile generators
Urban and residential areas
Hospitals and sensitive buildings
Containers and Acoustic enclosures

Product features

Each SMP silencer benefits from a robust design in carbon or stainless steel, guaranteeing strength and durability in demanding environments.
Standardized connections (PN10 flanges, bent or tapered edges) and radial or axial orientations facilitate integration into a variety of configurations.
Manufacturing is carried out to tolerances in compliance with ISO 13920 class B, ensuring precision and reliability. The SMP range covers diameters from DN50 to over DN800, making it suitable for both low-power motors and high-capacity industrial installations.

Key product benefits
