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