Acoustic constraints of high-power engines
The 1,500 kVA motors used in biogas applications generate significant noise emissions when the exhaust gases are evacuated. The challenge was twofold:
- Noise reduction with attenuation levels in excess of 30 dBA.
- Low pressure losses, essential for energy efficiency.
These constraints were compounded by a small footprint, making acoustic dimensioning particularly complex.
Groupe BOËT’s technical solution: SM EVO2 silencer
To meet this challenge, Groupe Boët has designed a custom-made industrial acoustic silencer: the SM EVO2.
Key features :
- 30 dBA sound attenuation for demanding environments.
- Optimized design to reduce pressure drop.
- Space-saving integration without compromising performance.
This type of engine silencer meets the standards of critical industries (nuclear, petrochemical, food-processing, pharmaceutical) and is part of a global approach to industrial noise reduction.
Applications and benefits for industry
The solution developed by Groupe BOËT illustrates its expertise in industrial acoustic studies, acoustic simulation and equipment sizing. SM EVO2 silencers are used in :
- Compressor silencers and booster silencers for wastewater treatment plants and pneumatic conveying.
- Acoustic silencers for noisy industrial machines on ICPE sites.
- Acoustic enclosures, acoustic panels, acoustic doors, acoustic grilles and sound-absorbing materials are all part of a complete solution.
This expertise contributes to improving acoustic safety in industry, reducing the environmental impact of noise and ensuring compliance with international standards such as ISO 9001 acoustic certification.
Conclusion and call to action
With the design of the SM EVO2 silencer, Groupe BOËT provides a high-performance, sustainable response to the noise challenges of biogas plants. This achievement demonstrates the Group’s ability to provide tailor-made industrial acoustic solutions, adapted to the most demanding requirements.
