The company Zöllner, which was founded in 1946, is a traditional manufacturer of acoustic signal systems for the shipping sector. This medium-size enterprise is the world market leader in this segment.

The product range of signal horns for vessels of all lengths has been extended to luxurious and modern models for super yachts. In addition to the production of acoustic signal systems – for the most part Makrofones® operated by compressed air – a new important business segment was introduced in the 1990s: the development, production and distribution of automatic warning systems for track work sites. The Autoprowa® -system is an automatic warning system for the collective warning of people working in the track area. All the modules of the system can be combined with each other, which enable an optimal and individual safety system for each track work site. Here we apply the latest radio technology. With the introduction of these failsafe systems the number of accidents on track work sites has been reduced significantly. In this market segment, the combination of high efficiency and a high security standard is of prime importance.

The company with subsidiaries in the UK, France, Australia and Spain is owned by the third generation of the family Murmann and is lead today by Dr. Philipp Murmann as its managing director. The head office in Kiel employs approximately 100 members of staff. Due to the vast expansion of the company in the last years, it has invested in a new custom-made building, which enables the optimal organisation of work processes.

The successful concept of the company ZÖLLNER is, besides its high quality, long lasting and innovative products, a staff of very motivated employees, a modern management style and constant investments in research and development.

We are your competent, flexible and reliable partner for safety on track work sites and develop innovative, pioneering solutions for your individual rail infrastructure requirements.
