Pitch Perfect Turbines that Run Smoothly.
At Ymer Technology, we design and supply hydraulic pitch systems for both onshore and offshore wind turbines. Our designs are based on long experience with the most demanding systems and applications, helping you maximize output while keeping the system protected.

Pitch System.

Optimum control of the blade pitch angle is important on all modern wind turbines, making the pitch system an integral part of the wind turbine. The pitch system not only ensures the pitch angle for optimum power control, but simultaneously works as the primary safety system on the turbine – thereby protecting it from overly strong winds. Our pitch systems consequently increase overall performance as well as the life cycle of the wind turbine.

Pitch Actuator.

The pitch actuator is the heart of the hydraulic pitch system, transforming the demand signal from the turbine controller into the right pitch angle. Different combinations of pitch actuators are possible – we can supply both one and two pitch actuators per blade. Using our proprietary software, we design the right sealing system to ensure long-lasting and reliable performance.

Power Pack.

The power pack (HPU) contains the oil reservoir and can take different forms. At Ymer Technology, we don’t just match your specifications, we also focus on creating a solution that is easy to service. Furthermore, the power pack can also handle auxiliary functions such as the control of yaw brakes, high-speed shaft brakes and the inboard crane. Our customized pitch power packs are easily integrated into the nacelle infrastructure. We include a cooling solution for the oil, ensuring an easy interface and optimized design resulting in minimal use of oil.

Service

Pitch Manifold.

The pitch manifold can have numerous different designs and functionalities, and can be installed as a central unit or on each of the pitch actuators. Our manifolds perfectly distribute oil to each of the blades, ensuring the movement of the pitch actuators while also including the safety circuit of the turbine. We tailor the manifolds to perfectly match the application, while focusing on reducing complexity.

Summary.

Our pitch systems are designed for superior turbine performance by integrating all components into a compact and effective design. We can include the electric pitch controller, thereby supplying a “plug and play” system that is both simple and, flexible. This gives you the highest possible reliability while leaving you the option of setting the desired blade position. In short: your pitch demand is in safe hands.

Production Chain.
A One-Stop Technology Shop.
We make complete cooling, thermal management and hydraulic systems from the ground up. Combining extensive engineering and application knowledge with state-of-the-art production means we can ensure superior quality, while keeping the time from order to prototype as short as possible.

Calculation
To Find the Best Solutions, We Look Into the Future.
Based on our extensive application knowledge and thermodynamic expertise, we have developed Seidr – a state-of-the-art calculation tool that models the behavior of fans, liquids, materials, headers and more. This helps us create a first, optimized layout before we
start modeling.
3D-model
A First Look at Something Really Cool.
After getting agreement on our layout, we begin modeling the design in exact detail. After we’ve thoroughly examined the 3D-model, it’s sent to you – no more than one week after the agreement is finalized.
Production drawings
Getting Down to the Nitty Gritty.
After your agreement, the final design is broken up into detailed production drawings to enable manufacturing of each individual part. With a complete bill of materials, it’s time to start production.
Component production
Making Sure There is No Weakest Link.
All parts included in the complete BOM of the final product are manufactured. Either internally in our own production facilities – we have full control of the production chain with capacity for aluminum matrix and steel production – or by handpicked and approved suppliers that meet our high demands on quality and delivery times.
Prototype assembly
Ready for Testing.
Every new product will pass a prototype assembly where both production and design thoroughly evaluate the prototype to ensure that all design and customer specifications are met or exceeded.
