Lund & Sorensen A/S has developed a special heating solution that deals with problems often encountered when wind turbines fitted with hydraulic blade pitch systems are installed in very cold areas.

Lund & Sorensen A/S manufactures specially designed heating

elements for hydraulic oil tanks placed in the nacelle or hub of wind turbines.

 

The viscosity of the oil in these tanks is very dependent on temperature. Heating the tanks therefore makes it possible to optimise oil viscosity.
