Emigreen® for integrated emission control solutions At Emigreen® we specialise in solutions. And we stand out from the crowd in this respect. Rather than promoting particular products, we develop integrated emission control solutions in response to customer requirements. To ensure compliance with regulations, to stop soot dirtying the deck of a luxury yacht, to devise a solution that will fit in a confined space. The requirements are many and varied but whatever the requirement, the Emigreen® solution is always highly reliable, fully controllable and impressively efficient.

Luxury yachts Emigreen® emission control solutions are always highly reliable, fully controllable and impressively efficient. Yet when it comes to luxury yachts, aesthetics are also important.

Our systems reduce exhaust noise, neutralise nitrogen oxide (NOx) emissions and trap soot particles so they no longer find their way onto the deck, into the swimming pool and into the water around the yacht. This gives the yacht designer more freedom in the positioning of otherwise emission sensitive components.

Exhaust noise reduction The exhaust noise from an engine is caused by the release of hot gas into the atmosphere in a series of high-pressure pulses, created when the exhaust valves open.

Different treatments for different bands of frequencies Although exhaust noise is made up of a wide range of different frequencies, it is possible to group the majority of the into three bands: low, medium, and high.

To attenuate exhaust noise, each band must be treated differently, and the silencer must be designed to reduce them harmoniously and simultaneously.
