Formulating for the future
As with many other lubricant applications, the demands placed upon gear oil lubricants are growing as contact pressures increase and oil lifetimes are expected to lengthen. In wind turbines especially, these oils must withstand extremely high contact pressures and temperatures whilst at the same time providing adequate metal protection.
Our lubricant technologies for wind turbine gears and bearings allow oil formulators to create the next generation of wind turbine oils and greases by harnessing our expertise in tribology and rheology control. We supply ingredients including base oils, solubilisers and friction modifiers.
Base oils for wind turbines
Ideal for the formulation of high-performance wind turbine lubricants
We have a long history in manufacturing base oils for lubricants and we offer a large range of both polyalkylene glycols (PAGs) and esters, from viscosities as low as 14.5mm²/s to 2000mm²/s at 40°C.
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 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 demonstrate 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 0.05m/s.
