General Information
ELECTRO–TYFON
®
MT 150/130 is an electrically driven
piston ship’s whistle. It is built up of comparatively few
moving parts as the “swinging piston”, no lubricated cylinder
and an oil free gearbox.
Important features:
• unsymmetrical sound distribution
• operates in all ambient temperatures without any
additional measures
• unaected by voltage and frequency uctuations
• oil free, maintenance free and non–corrosive
• easy to install
• complies fully with the International Regulations
IMO 1972

MT 150/130 will give a high
performance in both arctic and tropical climates.
A patented system with a high eciency rectangular
horn and a specially designed motor will match the motor
speed to the acoustic resonance of the horn at any
ambient temperature without any additional measures.
This system also prevents the whistle from being aected
by voltage and frequency uctuations in onboard mains.
Unsymmetrical Sound Distribution
The IMO Regulations stipulate a very high Sound
Pressure Level for ecient signaling, yet the sound level
of the vessel's own signal at the listening posts shall not
exceed 110 dBA.
A common way to solve this “paradox” is to place the
whistle very high above deck. But what if the highest point
is not high enough? For example: to reduce the noise
from the signal by 6 dB, the distance between the
listening post and the whistle must be doubled!
ELECTRO–TYFON

MT 150/130 with Unsymmetrical
Sound Distribution is the solution. The horn with its unique
vertically extended front, and a specially created sound
spectrum will reduce the noise on deck with 6–8 dB
compared to a conventional whistle with circular orice.
