SOUNDOWN WATERDROPtm SILENCER
Soundown's proprietary design WaterDrop tm silencer offers diesel exhaust super silencing, 10 to 20 decibels quieter than conventional systems with minimal increase in back pressure.
The principal of the silencer relies on using the engine cooling water to enhance silencing effect, after which the water is separated from the exhaust gas and silently (without water splash) discharged below the water line.
The de-watered and silenced exhaust can be piped as desired with very little increase of back pressure due to the low velocities of the cooled gas.
The noise levels of the generator exhaust with this system are usually in the range of quiet ventilation blowers. Propulsion engine exhaust is normally brought down to the ambient noise of the stern wash.
Applications include diesel generator and propulsion exhaust systems. Power range of existing applications of the Waterdrop silencers is:
Generators: 8 to 400 kW,
Propulsion: 12 to 2,000 hp.
Larger sizes and custom shapes are also available
