Engine Exhaust Silencers

We supply an entire range of silencers for diesel and natural gas engines for installations ranging from small to large, as well as all of the necessary accessories. We supply customised intake and exhaust flow silencers for every type of industrial application.

Silencers can be designed to fit the shape of any casing (round, rectangular, or oval), using a wide range of materials. Inlets and outlet will be arranged as required by the customer.

BBM spark arrestors

On request, our silencers can be equipped with integrated spark arrestors. These specially developed arrestors - certified by Det Norske Veritas - feature the following characteristics:

•    Compact design
•    High separation of particles
•    Best solution for maritime and off-shore applications
•    Easy cleaning of collection chamber
•    Good flow distribution for low pressure drop

Acoustic design and calculation

We design silencers with an attenuation range of 10 to 60 dB(A). The silencers can be the absorbing, resonator, or reactive type, and in most cases a combination of these. Acoustic and velocity/pressure drop calculations for each design have to be executed in parallel to get the most optimised result. We also offer space-saving solutions.

Our acoustic designs include optimised solutions for the entire system. BBM Akustik Technologie guarantees the entire system, based on our R&D and site measurements.
