Development partnership for wind turbines: our product solutions
Combined systems from HYDAC
The best of all worlds, combined with our expert knowledge of our in-house components: with our experience, we're able to efficiently combine different components and optimise the positioning of individual modules. Whether it's combining components for a cooling circuit for generator, inverter and gearbox cooling, a space-saving solution for gearbox lubrication, water cooling or hydraulic power packs for brake and pitch.
HYDAC generator cooling
- Air-air cooling systems for generator cooling in wind turbines
- Project-specific design in the multi-megawatt range
- Offshore application: separating salty air from generator cooling air circuits
- Special coating to protect against corrosion
- Easy maintenance
- Air-air cooling is the most reliable and sustainable method for offshore wind turbines
HYDAC Cold Plates
Cold plates are used wherever electronic components operate at high power and need to be cooled efficiently, e.g. for cooling IGBTs in inverters or ceramic brake resistors during wind turbine shutdown. Thanks to our expertise in fluid cooling, the impact of real, customer-specific installation situations on cooling performance can be investigated, allowing the cold plate to be optimised accordingly.
HYDAC integrated filter block solution + MCS
With over 25 years of experience in wind power, HYDAC develops modular filtration solutions with integrated components such as valves, bypasses and optional sensors. Sustainably save on pipework with our integrated filter block solution.
System availability
Thermal stress and contamination take a toll on components and systems in the long term. We use our experience to present you with solutions for increasing your wind turbine's availability and service life – with intelligent sensors for monitoring and analysing your data. This means that wear processes in gearbox and bearing lubrication systems, for example, are recognised at an early stage and serious consequential damage is avoided.

HYDAC Metallic Contamination Sensor
The HYDAC Metallic Contamination Sensor is used to detect metallic solid particle contamination in lubrication fluids. Detect damage to your gearbox early on and avoid costly system failures – also suitable for retrofitting.
HYDAC filter element BN4HX
The 2-stage element from HYDAC ensures that only filtered oil reaches your wind turbine's lubrication system, even when the bypass valve is open – thanks to the integrated protective filter. Increase the availability and reliability of your wind turbine with our BN4HX premium element.
CO1 compact power units
Our compact electro-hydraulic supply units for three-phase power supplies are ideal for energy-efficient intermittent and short-time operation. They are perfect for stationary applications such as braking and locking functions in wind turbines. As they can be flexibly equipped with cartridge valves and expanded with control blocks or function modules, they offer a high degree of flexibility.
