KAEFER develops high-performance components and solutions for acoustic challenges on ships in its own sound laboratory. We use construction plans, engine features and other data to dimension and manufacture air intake, air extraction and exhaust silencers for sound insulation.

KAEFER silencers are made of anti-magnetic steel. This steel is extremely demanding to produce, weld and construct due to the thermal tensions and cracks which can arise in subsequent operations. We have managed to build a construction which has proven long-term stability while maintaining agreed noise levels.
