Reliability high up – Cognis presents solutions to boost wind turbine efficiency at Husumwind 2007

Published on 2007-09-21. Author : SpecialChem

Monheim -- Wind power plants, like the wind energy market itself, are growing. At this year's Husumwind trade show in Husum, Germany, global specialty chemicals supplier Cognis highlighted products that lower the stresses turbine components are under: Breox SL 320 gear oil, and ProEco HE 801 series hydraulic fluids. For coating improvements, Sovermol polyols were on the display. These combine to form a complete package of solutions that help wind farm operators extend the service life and increase the efficiency of their equipment.

Since gearboxes are both among the most stressed and most expensive components, their durability and reliability are especially important for everyone who operates wind turbines. A key factor here is the quality of lubricants - Breox SL 320 polyalkylene glycol-based gear oil offers the specific performance properties required for use in wind turbines, and it is ecologically sound. Thanks to its outstanding micro-pitting resistance and bearing wear protection, high load-carrying capability, reduced operating sump temperature, and clean operation, Breox SL 320 helps improve reliability and extend drain intervals, thereby significantly enhancing the overall profitability of the power plant.

The ProEco HE 801 series is a range of high-performance, anti-wear hydraulic fluids. With excellent pump test and FZG load-carrying performance, good seal compatibility, and superior oxidative stability, they improve turbine efficiency, even in extreme climates. Based on renewable ester technology and being readily biodegradable, they also meet the standards for the EU Ecolabel.

Rotor blade coatings containing Sovermol polyols offer effective protection against the many environmental hazards that the blades are constantly exposed to, including UV light, salt water, and rain. These factors are a particular area of concern in offshore wind farms. Sovermol products provide superior adhesion and hydrophobicity, high rupture resistance and high chemical stability. They are also naturally sourced and free from volatile organic compounds (VOC) or solvents, making them environmentally sound.

All-round solutions for wind farms

Comments Patrice Pinsard, Vice President Marketing and Business Development Functional Products: "The technical challenges of turbines that are up to 100 meters high in offshore and other remote locations can be daunting, but we are sure that the solutions we provide will aid manufacturers in extending the intervals between costly maintenance works. In this way, we are helping to maintain momentum in this fast-growing market, so that it can continue to grow at the rate we have seen in recent years."
