Engine exhaust silencers SMC
Groupe BOËT’s SMC40 engine exhaust silencers are designed to provide optimum noise reduction for internal combustion engines in the most demanding industrial environments. Developed by the Research & Development department, it combines a reactive system with a sound-absorbing device, guaranteeing high performance even under severe operating conditions. Its compact, robust design allows easy integration in confined spaces such as containers, hoods or enclosures.
Durable acoustic solution to reduce engine noise in compact environments
Thanks to the combination of a reactive wave-shifting system and acoustic absorption technology, the SMC40 silencer offers a guaranteed attenuation of 39 dB(A). This result is due to enhanced low-frequency efficiency, complemented by broadband absorption covering the entire sound spectrum.
This performance makes it an ideal industrial acoustic solution for engine noise reduction in power generation plants, urban generators or installations in noise-sensitive environments. Designed to last, the SMC40 maintains its acoustic performance while preserving engine efficiency.
Field of application
Product features
The SMC40 silencer for diesel, gasoline and gas engines combines compactness and efficiency. Its welded cylindrical design ensures high mechanical strength and easy integration, even in confined spaces. Available in S235JR carbon steel as standard, it can also be manufactured in 304L, 316L stainless steel or other alloys for more demanding environments.Connections are made via standardized PN10 flanges (up to DN400) or other standards on request (BW, BS10, WN…), guaranteeing maximum compatibility. Different radial or axial orientations enable optimized integration according to installation constraints.
Key product benefits
The SMC40 silencer offers several benefits for industrial operators:
Product options
Made-to-measure
Each custom-built SMC40 exhaust silencer is designed taking into account gas flow, permissible pressure drops and project-specific constraints. Thanks to precise sizing (DN50 to DN450, weights from 31 to over 660 kg), it guarantees an ideal compromise between engine noise reduction and energy performance.
This customized approach enables the silencer to be integrated into power plants, compact containers or urban generator sets. Groupe BOËT supports its customers from the initial design stage right through to commissioning, offering solutions perfectly adapted to the realities of the field.
