Classic Waterdrop Silencer Sizing and Configuration Guide The classic waterdrop silencer is ideal in installations where the waterline is low and foot print area i; • Inlet locations are typically at the lowest or highest point of silencer. • Outlets in most cases can be located anywhere on the silencer. • Drain is located on the lowest part of the shell, or on the bottom face. Available Sizes____ Custom sweep and mitered elbows NPT ports for pressure testing, thermocouples, etc. Wide range of custom mounting rings, feet, etc. High-grade finish.

JoUNOOWN F0* peice **s QUIET Classic Waterdrop Generator Exhaust Installation Notes Generator Exhaust System • Keep exhaust components in close proximity to one another. • Drains should be minimum 12" above waterline. Drain should travel to min. 6" below DWL. All horizontal runs should be minimized and pitched. • Path from lift to silencer should be as direct as possible to minimize backpressure. • Minimize bends in the piping between lift & waterdrop. If silencers are offset from each other, rise from the lift then run to the waterdrop. • Minimize or eliminate bends and upward inclines in...

OUNDOWN F0* PEICE -|:: QUIET Classic Waterdrop Propulsion Exhaust Installation Notes Propulsion Exhaust System • Silencer to be installed level. • Silencer to be below dry riser or wet elbow. • Minimize or eliminate bends and upward inclines in all exhaust pipe routing. • Drain piping must nol be restricted in cross sectional area along the route to discharge. • Partial raw water bypass is a potential requirement of all exhaust systems.

JoUNOOWN F0* peice **s QUIET Axial Waterdrop Silencer Sizing and Configuration Guide The axial silencers are ideal in installations where water line is high. • Inlets are located on the end plate or side shell near one end of the silencer. * Outlets are located high on the end opposite the inlet. • Drains are optional and located on the outlet end, low on the silencer body. • Elliptical silencers are available if standard cylindrical dimensions do not meet spatial Available Options • Flanged connections with rotational backing rings. • Custom sweep and mitered elbows • NPT ports for...

OUNDOWN F0* PEICE -|:: QUIET Underwater Discharge Tower Silencer/Low Speed Bypass Silencer Sizing and Configuration Guide Tower silencers with low speed bypass silencers are ideal for high power propulsion engines. • Inlets are located at upper portion of canister. • Outlets typically go straight out the bottom towards underwater discharge penetration. • Low speed bypass may be of Classic Waterdrop or Axial Waterdrop design. Available Options • Horizontal (Flying Tower) configurations. • Flanged connections with rotational backing rings. • Custom sweep and mitered elbows • NPT ports for...
