Optimised solutions for environmentally sustainable technologies
Hydraulic control
Deublin rotary joints for wind power are available with one to four high-pressure hydraulic channels, as well as central passages for connecting electrical slip rings.
1 channel
These compact rotary joints are designed for wind turbines controlled by shutdown, which typically have a power output of 1 MW or less.
2 channels
Deublin rotary joints incorporate durability features that significantly reduce downtime and maintenance costs, for both onshore and offshore operations.
3 channels
All Deublin wind turbine couplings are 100 per cent factory-tested under operating pressures to ensure that each coupling is fully operational on delivery and ready for installation.
4 channels
Deublin rotary joints for wind power utilise patented controlled-leakage sealing technology. The four-channel rotary joints accommodate both small, controlled movements and large, rapid changes in blade pitch.
Electrical control
Deublin electrical slip rings transmit analogue sensor signals, high-speed digital data and power to provide reliable monitoring of conditions inside rotating blades, hubs and other components. Deublin products help to meet the growing public demand for clean energy.
30 to 750 volts
Bespoke interfaces
Deublin electrical slip rings can be configured with terminal blocks, rectangular or circular multi-pole connectors, as well as MIL-SPEC connectors.
Integrated solutions
Deublin supplies combinations of rotary joints and slip rings for the transfer of fluids and electrical signals.
