"Triton" Electric Piston Horns utilize a 7.5 to 10 horsepower electric motor to drive a piston which oscillates air in a column. With an entirely oil-less crankcase and gear case, steel gears, anti-condensation heating and self-draining cylinder assemblies, these piston horns are highly reliable ship's whistles requiring virtually no maintenance. Installation costs are minimal since no air or steam piping is required.
• Piston horn is electrically powered and IMO certified for
vessels over 75 meters and over 200 meters in length
• Horn construction: High strength aluminum bell, supporting
frame, aluminum crankcase, stainless steel cylinder
and fasteners
• Self draining design to prevent condensation and corrosion
• Oil free, heated crankcase and piston cylinder assembly
• Motor is totally enclosed, marine type, IP56, insulation
class F and equipped with anti-condensation strip heater
• Motor starter (contactor) comes with solid state, temperature
compensated relay that is field adjustable with thermal
overload protection
∗ Signal will produce a sound pressure level of approximately 70 dB @ 8
km in calm, cool conditions without topographical interference. Signal
strength at distance can vary dramatically depending on environmental
and geographical conditions. Please consult factory for more detailed
