Proven Solutions for Onshore and Offshore Wind Energy
Modern wind power systems rely on durable components to operate efficiently and safely. Continuous performance in remote, harsh environments—where maintenance is costly and time-consuming—is essential. Penlink’s fluid rotary unions deliver reliable hydraulic power to blade actuators, enabling precise pitch control that maximizes energy output and minimizes downtime.
For seamless integration, our electrical slip rings can be combined with fluid rotary unions to provide signal and power for hydraulic pitch control systems. Designed for the toughest conditions, our solutions often include lightning protection, heaters, and encoders to ensure reliable operation. Additionally, we have delivered numerous designs featuring integrated Fiber Optic Rotary Joints (FORJ) to support high-speed data transfer needs.
With extensive experience and thousands of installations, Penlink’s rotary unions and slip rings are trusted by leading wind turbine manufacturers for both onshore and offshore environments.
