DEVELOPMENT, MANUFACTURING AND SALES OF BLADE PITCH SYSTEMS FOR WIND TURBINES FROM 500 KW UP TO 10 MW

Especially the blade pitch system is our focus. We know the special application conditions where the system has to work reliable.

We always push on the technology. Our in-house developments are approved.

Day by day thousands of OAT Pitch Control System Installations in customized versions demonstrate functional efficiency in the rough daily use on locations all over the world. From day to day more and more systems are installed.

Conception:
New servo converter, reliable battery and ultracap systems, AC motors and compact DC motors, integrated control functionality based on forward-looking technologies are the core of the OAT-concept.

Quality:
All these technology is robust, with high efficiency and anyway compact construction. So it guarantees a long term application onshore and offshore.

The CEO Henry Osterholz as manager of the Ingenieurbüro Osterholz has decades of experience in wind energy
Already in 2001 increase of several employees in research and development and in sales department
Foundation of OAT in 2005
Also in 2005 patent application for key components of the OAT pitch system
Pitch systems for 0,5 up to 10 MW
Up to the present more than 10000 wind turbines worldwide are equipped with OAT pitch systems and work under sometimes most difficult conditions
Certified to ISO 9001 and
Certified by DNV-GL
