Renewable Energy

Renewable or environmentally sustainable technologies require rotating unions for a variety of applications including wind and solar energy. Wind energy use Deublin high-pressure rotating unions for wind turbine hydraulic slip ring pitch control rated for millions of cycles and years of trouble-free operation. Solar technologies harness radiant light and heat from the sun for applications that include solar heating, solar photovoltaics, solar thermal electricity and solar architecture. 

Pitch Control for Wind Energy Turbines

Deublin high-pressure unions for wind turbine hydraulic slip ring pitch control unions, are available in 2-4 passage configurations, with central passages for cable connections to integrated and optimized Deublin electrical slip rings.

Solar Energy 

Deublin rotating unions are used in multiple applications including heating and cooling of films used with photovoltaic panels to absorb solar energy, and to transmit hot water or other fluids from photovoltaic panels to a header panel for different uses.
