ZET-Horn (70 AC)

The ZÖLLNER ZET-Horn was the first piston type whistle on the world market driven by an AC 3phase motor. An essential component is the piston inside the cylinder driven by an AC 3phase motor via connecting rod, crankshaft and gearwheels. The piston oscillates at a certain frequency which makes the air inside the sound horn vibrate in resonance to produce a sound audible over a wide range.

ZET-Horn (70 AC)


The ZÖLLNER MAKROFON M125 is a diaphragm sound transmitter operating on compressed air. The signal is released by an electromagnet or manually using a hand pull-rope. To avoid the costly laying of a pull-rope, a second electromagnet for emergency voltage can be provided. A thermostat controlled anticondensation heating keeps the sound horn and the operating valve free from condensed water and thus from ice.

ZETFON (300/310)

The ZETFON 300/310 is an electronic sound transmitter. It consists of the ZETFON (sound emitter) itself mounted on the mast and a control and amplifier unit for wheelhouse installation. The control and amplifier unit contains all electronic components including the heavy transformer. This way heavy weight on the mast is avoided and vital components are within easy reach. The ZETFON is an economic alternative to air whistles on vessels without air compressor.
