REETEC launches new aviation obstruction markers for onshore and offshore wind turbines according to latest certification standards

After completion of the development work, prototypes of the new luminaire series were initially built in the company's own production facility in April 2017; after successful certification of the optical characteristics, REETEC is now starting its series production. Consistent simplification of components and design resulted in a significant cost reduction. At the same time, the robustness and longevity of the luminaires were key development objectives.

The most important improvements at a glance:

• The number of LED levels was minimized - this design optimisation allowed for a much more compact model shape
• Newly designed, robust Plug'n’Play GPS solution with integrated twilight switch
• Highly flexible system that can be easily adapted to local requirements via network / web interface
• Individually configurable, therefore suitable for retrofit

“The above are all decisive advantages of the new aviation obstruction markers compared to the previous generation. Our goal was to maintain the tried and tested robustness while at the same time implementing technical innovations and a cost-efficient production,” explains Carsten Bredemeier, Head of Development at REETEC.

Comprehensive environmental testing under real life conditions

The prototypes underwent a comprehensive test program: examinations in climatic and pressure chambers, salt water spray tests as well as acceleration and shock tests that go beyond typical environmental conditions and manufacturer requirements. The optical properties have been tested by an accredited laboratory and were successfully certified by the relevant authorities according to current AVV and ICAO guidelines, which is a prerequisite for marketing approval.

"Within only one year we have developed, extensively tested and successfully certified a completely new product. Our new aviation obstruction markers pay tribute to the rapiddevelopment in the field of LED technology and raise our product portfolio to a new technical level. The market interest is extraordinarily high, as the system is also very well suited for retrofit measures due to its modularity," says Claus Sejersen, Sales Director at REETEC.

The results which REETEC repeatedly achieves on the basis of its broad experience and comprehensive know how are an integral part of the success story of the Bremen-based wind energy company from day one: REETEC has been producing aviation obstruction markers for onshore and offshore wind turbines since 1998.
