Flexible, user-friendly, well-designed and supplied with all relevant certificates – ZÖLLNER Makrofons® provide the optimum solution with impressive durability.
In the first years after our foundation in 1946, ZÖLLNER compressed-air operated signal horns were already installed on rail vehicles. At that time, so-called whistles were used to warn of the approaching vehicles. Signal horns with different frequencies with 660 Hz and 370 Hz and often in duplicate are used for the same purpose in today’s rail vehicles.
Since 2020, with our new electrical Makrofon EM660/370 TSI, we have been offering a solution for signalling that is independent of compressed air.
Increasing demands on the material, documentation and safety support us in offering high-quality and reliable products. We place particular emphasis on compliance with environmental requirements such as REACH, ROHS and EN 45545.
Not least, developing individual solutions and modifying products together with our customers and partners is one of our passions.
We offer acoustic warning devices for the heavy rail industry as well as for the entire light rail sector.
The electric actuation of our electrical Makrofons offers a signalling variant that is quickly operational and is independent of the compressed air supply.
For decades, compressed air-operated Makrofons have guaranteed reliable signalling in railway transport.
The Zöllner Makrofons of the ZM75 series are characterised by a long service life and low maintenance costs. The Makrofons consist of a brass casing and a sheet steel funnel. Sound is produced by a diaphragm, which is fixed in the casing by two O-rings. The funnel is screwed into the casing. The Makrofon can be additionally fitted with a heating system and a protection grid or mesh. Our Makrofons are available in UIC 644 and TSI EN 15153-2 versions.
