As with many other lubricant applications, the demands placed upon gear oil lubricants are ever-increasing as contact pressures increase and oil lifetimes are expected to lengthen. In wind turbines especially, these oils have to withstand extremely high contact pressures and temperatures whilst at the same time providing adequate metal protection. One of the most crucial issues in modern gear oils is the occurrence of scuffing and micro-pitting leading to excessive wear or, in extreme circumstances, mechanical failure.

Our ester, Priolube 3970, is used extensively in wind turbine formulations, most notably in Siemens approved lubricants to improve additive solubility, whilst maintaining oxidative and hydrolytic stability.
Perfad 3100 is a friction modifier from our range that can provide excellent friction reducing properties to wind turbine gear oils, more efficient power transfer and reduced running costs, whilst having minimal impact on water entrainment. It forms a durable film, most notably in the mixed and boundary regime where energy losses are high. Friction reducing effects have also been observed at high temperatures, as found in heavily loaded contact areas.
The graphs below demonstrates that Perfad 3100 can provide reduced friction over a range of different contact pressures, from 0.65 GPa up to 3.2 GPa at a constant speed of 0.05 m/s.
