Hydroelectric Power

Used in renewable energy

Delivering power to adjustable turbine blades for optimal velocity flow in both high and low water levels.

Designed for hydropower environments, Our rotary unions (joints) are engineered for continuous and reliable operation providing supply and return hydraulic power to blade actuators for adjusting pitch to adapt to flow conditions. Integrated with electrical slip rings and positioning sensors, rotary unions can provide precise and reliable position feedback in addition to fluid transfer.

Solar Power

Used in Renewable Energy

We provide various solutions for renewable and alternative energy applications. We can provide rotary union designed to provide rotational movement to collector piping in a parabolic trough concentrated solar power (CSP) field. Features include a specialized high temperature packing sealing system, internal corrosion-resistant bearings, and a customer-specified design for direct welding to the piping system.

We can also provide turnkey solutions in to move solar panels 360 degrees to optimise the position of the solar panels. Products include electrical slip ring, encoder, motors and drives. 

Our SWIR cameras can inspect solar panels via tripod or drones, please read our application note on Solar cell inspection down below.

Wave Power

Used in Renewable Energy

Our fluid rotary unions (joints) provide reliable fluid transfer for hydraulic actuation needed to adapt to wave conditions. Our fluid-electrical and positioning sensor integration provides a reliable solution for accurate synchronization and pitch scheduling to improve the efficiency of power conversion and lower the cost of energy.

Wind Power

Used in Renewable Energy

Today's leading wind turbine manufacturers demand reliable, high-performance components capable of operating continuously in the toughest environments, often in remote locations, where maintenance is difficult and cost-intensive.

Our  fluid rotary unions for hydraulic blade pitch control systems deliver dependable hydraulic power to blade actuators for greater productivity and less maintenance-related downtime - translating to significantly reducing operation and maintenance costs.

Our electrical slip rings can be integrated into the fluid rotary union, providing signal and power for the hydraulic pitch control. Often integrated with lightning protection, heaters and encoders. We have also done and sold several designs with integrated FORJ (Fiber Optic Rotary Joint).

With over 2,000 blade pitch control rotary unions in service, our solutions with our partners field-proven designs deliver the highest performance for both onshore and offshore environments.
