Components, systems and service for all wind turbines
The gearbox in a wind turbine is the link between the rotor and generator. It converts the slow rotational movement of the rotor with high torque into a fast rotational movement with low torque. Tailored systems are required for the gearbox to be able to withstand these loads. HYDAC offers solutions for gearbox lubrication, gearbox cooling and oil filtration that are tried-and-tested on the market.
Pitch & brake control
Safety is critical for long-term successful operation of your onshore and offshore wind turbines. Pitch control reduces the risk of mechanical damage and thermal overload. Efficient braking systems also prevent expensive failures and repair costs. To increase your cost efficiency, discover our reliable and robust power units for brake, pitch and yaw adjustment.
Generators & inverters
Wind turbine generators require some special features due to the connection to the rotor which results in strong fluctuations in mechanical performance. Whether it's a fixed rotor speed with direct grid feed-in or a variable rotor speed with an inverter– the optimal cooling system is crucial for ensuring high functionality. HYDAC is on hand to help you with extensive expertise in cooling (even for extreme climate zones, CCV & HCV).
Continually rotating bearings enable the rotor to turn on its own axis. As the main bearing constantly has to withstand extreme loads, it must be able to meet the highest of requirements. To ensure the highest level of safety and reliability, HYDAC is at your side with extensive know how and optimised lubrication systems for low-maintenance operation of your wind turbine.
Cable guiding plays an important role in increasing the performance of cables in towers and loops. With our new HYROFLEX cable mounting system, we have been able to lengthen the cable service life and increase the cooling effect. This allows power cables to work more efficiently. Mounting supports in various versions and different cable groupings are available on request.
Reduce, reuse, recycle – save energy and costs sustainably with HYDAC. Increase your fluid service lives with our innovative solutions. With these solutions, you'll instantly be able to extend the intervals between maintenance. HYDAC helps you to use your resources in the best way possible and prepare components and systems for your wind turbine.
Sustainability in wind turbines: our product solutions
HYDAC fluid sensors and oil condition sensors
Many parameters can be measured with online oil condition monitoring: solid particle contamination, wear particles, water, temperature, dielectric constant and electrical conductivity. Sustainably optimise your wind turbine maintenance processes with fluid sensors or ready-to-connect monitoring solutions.
NF Extension Kit for HYDAC gear oil filters
The NF1310 (left) becomes the NF2210 (right): increase the filter size of the series filters installed in your system. With our NF Extension Kit – consisting of a filter tube, new seals and a larger filter element – you can sustainably reduce filter changes, service time and filter costs. Reap the benefits of longer service lives now.
HYDAC GBX+ cooler
More efficient, low-waste and more sustainable – save CapEx expenditures as well as OpEx expenditures with our optimised gear oil cooler! With its reduced weight, lower oil volume and minimal energy consumption, our GBX+ cooler makes an important contribution to optimal system operation.
HYDAC main bearing lubrication
HYDAC helps you to lubricate your main bearing efficiently. A longer service life can be achieved with constant cleaning of the lubricant in comparison to lubricating with grease. We'll work with you to find your optimal solution!
Thermal stress and contamination take a long-term toll on components and systems in the wind power industry. We use our experience to present you with solutions which increase the availability and service life of your wind turbines – with intelligent sensors for monitoring and analysing your data. Wear processes in e.g. gearbox and bearing lubrication systems are detected early on and serious consequences are avoided.
