Waterdrop Exhaust Silencers
Lloyds approved FRP wet exhaust systems
Main engines and generators
Discharge above water, below water, or stack
Custom configurations to fit any machinery space
Patented designs for the quietest yachts
How do Waterdrop Silencers Work
Exhaust gas and water are separated inside the muffler to allow our tuned resonators to cancel exhaust tones. This eliminates exhaust rumble and splashing that can be heard on deck or in the accommodations.
All internal components of our Waterdrop Silencers are designed to your application. This allows the internal resonators to be tuned to the firing rate and gas flow of your engine.
With the water and gas separated cool dry exhaust gas can be routed overboard, underwater, or up the stack in FRP tubing reducing weight and installed cost of steel piping and insulation.
Generator Installations
Conventional Waterdrop Silencer
Vertical format provides the greatest degree of water and gas separation.
Recommended for stack discharges.
Systems with integrated soot sinkers greatly reduce floating soot particles
Generator Installations
Axial Waterdrop Silencer
Horizontal format is configurable into the tightest machinery spaces
Can be configured for installation on top of generators where floor space and walking areas are limited
Mounting options from above or below
Propulsion Engine Installations
Towers Mufflers
Gas/water separation system facilitates the quietest installation.
No engine noise
No splashing of water
Configurable for hullside or stack discharge
Custom parts can be designed to fit in even the tightest engine room
Systems with integrated soot sinkers greatly reduce floating soot particles
Lloyd’s of London approved
Propulsion Engine Installations
Towers Mufflers
Designed to provide quieting of gas exiting below waterline in a compact muffler
Minimal back pressure contribution
Used in conjunction with a Conventional Waterdrop for critical silencing of bypass
Ideal for midship or aft engine room configurations.
Equipped with 150lb class flanges for classified vessels
Propulsion Engine Installations
Axial Waterdrop Silencers
Axial format is ideal for installation outboard and aft of main engines.
Round or elliptical shells allow these silencers to be optimized for the avialable space without sacrificing critical internal volume
Water can be drained away separately or recombined with gas for a common discharge
Available with multiple inlets for twin turbo or triple/quad engine installations
