Wet Exhaust Systems
The secret to quiet wet exhaust systems lies in the silencer selected. A good silencer separates the noisy water, soot and air into components, storing the soot, releasing the water slowly, and channeling the air out of the vessel in a pure and least noisy state.
In one of the most common example scenarios, a classic waterdrop silencer will take the water out of the steamy exhaust gas and release it below the water line to reduce both splashing and the weight of the exhaust travelling through the rest of the system. Using an active silencer with a tuned resonation limiter will cancel out the specific remaining wavelengths created by that process. This can also thereby negate the sound of the exhaust. Active silencer are an option; they come with tune resonation limiters, which cancel noise by affecting the resonant frequency inside the exhaust. Every engine has a maximum allowable back pressure – too much of it creates an affect like sticking a banana in a tailpipe. Soundown will implement exhaust systems with back pressure requirements in mind, so engine performance isn’t compromised and warrantees aren’t voided.
Soundown often uses patented technology to achieve ideal results, depending on the vessel and its configuration. Soundown’s silencers are approved by Lloyd’s of London, meeting any required insurance standards, and have been certified by the International Maritime Organization (IMO), a certification that includes testing by Lloyd’s of the systems’ ability to consistently provide quality over the long term.
We also pay attention to implementation and the general aesthetics of the system, making sure that the level and tone of finish matches its surroundings for a visually appealing silencer.
We’re proud to produce some of the world’s quietest exhaust systems for engines, pumps, generators and even ACs
