Conception de silencieux d'échappement des gaz de groupe électrogène de secours

Design of emergency generator exhaust silencers

Design, qualification and production of an initial series of two exhaust silencers for emergency power units in PWR (Pressurized Water Reactor) nuclear power plants.

The muffler design was developed exclusively to meet the specific requirements of the project:

– Guarantee acoustic attenuation of 50 dB with specific reagent for treating low frequencies
– Integrate into existing exhaust system without altering engine performance
– Guarantee mechanical integrity in seismic and shock wave conditions on site
– Reduce on-site installation time

Thanks to our experts in the nuclear field, our customer can benefit from dedicated project management and document traceability from engineering to manufacturing.
