Turbine oil increases the efficiency of hydroelectric plants

New speciality lubricant for plain bearings in generators

01/17/2019, Munich

Cost pressure, sustainability goals, influences from the market as well as environmental and renaturalisation measures force operators of hydroelectric power stations to generate energy even more efficiently and profitably.
This can be done either by reconstructions or by investments in new technology. Minor measures can already make an important difference without incurring high costs. With the new high-performance lubricating oil Klüberoil EE 1-46, Klüber Lubrication has found a sustainable solution for optimising the efficiency of both existing and new installations.


"The turbine oil was developed in cooperation with a leading European manufacturer of hydroelectric power stations. The reduction of internal friction optimises the efficiency loss in plain bearings. Klüberoil EE 1-46 complies with the requirements of the DIN 51515-2 standard. The high-performance lubricating oil can be used in all types of hydroelectric power stations - run-of-river power stations, storage power stations, pumped storage power plants - for oil-lubricated turbines and generators" says Florian Held , Global Project Manager Hydropower, Klüber Lubrication.

The expert for speciality lubricants has used a new, unusual approach in developing the new oil. The aim was to manufacture an oil for turbines and generators which increases the efficiency in plain bearings of generators. The semi-synthetic plain bearing oil Klüberoil EE 1-46 can substantially reduce efficiency losses in generator bearings.

The new energy-efficient turbine oil shows a low foaming tendency and high oxidation stability. The use of Klüberoil EE 1-46 optimises efficiency and extends oil change intervals, thus contributing to increase the service life of components. Hence, cost savings can be achieved easily and efficiently. Klüberoil EE 1-46 also shows good compatibility with plain bearing materials.

As a market leader in eco-compatible lubricants Klüber Lubrication offers already today a high-quality range of lubricants for hydroelectric power stations. The expert for speciality lubricants will continue expanding its product portfolio in the next few years while including its experience gained in other industries and sectors. Klüberoil EE 1-46 is the first product of a whole series.
