Renewable Energy

Hydraulic Control

Deublin rotary unions for wind energy are available with from one to four high-pressure hydraulic channels, as well as central passages to connect electrical slip rings.

1-Channel

These compact rotary unions are designed for stall-regulated wind turbines, which most often have a power output of 1 MW or less.

2-Channel

Pitch-regulated wind turbines demand reliability over millions of cycles. Deublin rotary unions include durability features that significantly reduce downtime and maintenance costs for both on- and off-shore operations.

3-Channel

All Deublin wind unions are 100% factory tested under operating pressures to ensure that each union is completely operational upon receipt and ready to install.

4-Channel

Deublin rotary unions for wind energy employ a proprietary, controlled leakage sealing technology. Four-channel rotary unions provide both small controlled movement as well as large, fast changes in blade pitch.

Electrical Control

Deublin electrical slip rings transfer analog sensor signals, high-speed digital data and power to provide reliable monitoring of conditions inside rotating blades, hubs and other components. Deublin products help satisfy the growing public demand for clean energy.

30 to 750 Volts

Made-To-Order Interfaces

Deublin electrical slip rings can be configured with terminal blocks, rectangular or circular multi-pin connectors, as well as mil-spec connectors.

Integrated Solutions

Deublin provides rotary union and slip ring combinations to transfer electrical and fluid media.

Self-Heating

Hydropower

With integrated durability features, such as corrosion-resistant materials and hardened sealing surfaces, Deublin unions offer unparalleled design life that provides stable, consistent performance over millions of cycles.
