New base oil from Evonik keeps wind turbines turning

January 19, 2017

Operators of wind energy farms place steep demands on the gear oil for their wind turbines: long oil drain intervals, sustained optimal viscosity of the oil over a wide temperature range, and maximum durability and long life for the gearbox. In VISCOBASE® 5-220, Evonik has developed a synthetic base oil that sets new standards in the field. As the critical key component of lubricants formulated to Evonik’s NUFLUX™ technology standard, it has, in short order, received the essential “thumbs up” from the key
industrial gearbox manufacturers. With these critical approvals, the way is now open for other high-performance gear applications.

“Wind turbines are tough testing grounds for gearboxes and gear oils: they need to perform as long as possible in a maintenance-free state despite constantly changing weather conditions and temperatures, humidity, and peak loads during storms,” explains Sofia Sirak, Evonik’s Oil Additives Innovation Manager for North America. “Until now, the gear oils of choice have been synthetic formulations based on polyalphaolefins. But with VISCOBASE® 5-220, based on polyalkyl methacrylates, this could now change,” she adds.

Tests conducted by FZG, the international research center for gears and transmissions, are regarded as the industry standard. And Evonik’s VISCOBASE® 5-220 formulation has now passed the FZG bench test and earned a very important approval. More importantly, over the past two years, Evonik has shown that gear oils formulated to NUFLUX™ technology standards with VISCOBASE® 5-220 have a particularly long service life between fewer drain intervals. They improve energy efficiency by maintaining an optimal viscosity across an expanded range of operating temperatures – from cold to hot.

The VISCOBASE® 5-220 base oil is one component of the novel NUFLUX™ technology with which Evonik is making its formulation expertise available to its customers. More precisely, NUFLUX™ technology is the collection of products, formulation concepts and services that Evonik provides to customers in need of resource-efficient industrial lubricants.

“Now that both base oil and formulation technology have succeeded in the tests developed by the industry leaders in gearbox design and manufacturing,” explains Dr. Ralf Duessel, Senior Vice President and Managing Director of Evonik’s Oil Additives business line, “Evonik is now positioned for expansion into other applications, such as mining and steel production, which are two of the largest markets for industrial gear oils.”
