2 Mobilgear SHC XMP 320 Balanced Formulation Wind Turbine Gearbox Lubrication Wind turbines are highly engineered and sophisticated pieces of machinery, operating in varied and demanding environments. Proven Performance for your Wind Turbine Gearbox Today Mobilgear SHC XMP 320 remains the initial-fill gear oil of choice for the majority of the world s top wind turbine builders and is now being used to protect more than 40,000 wind turbines gearboxes worldwide. It is an excellent lubricant for gearboxes used in wind turbines because it extends the performance of conventional mineral-based oils with benefits including extending the interval between oil changes from 18 months to three years or more. Balanced Formulation Endorsed, Approved or Proven Performance in: As such when selecting wind turbine gear oil, it is very important that the lubricant is up to the task and offers. Superb long term gear and bearing wear protection Excellent oxidation stability resulting in extended lubricant life Outstanding rust and corrosion protection Exceptional filterability and keep clean performance Wind Turbines Gearbox Acciona, Alstom, Goldwind, MHI, Nordex, REpower, Vestas NEG Micon, Suzlon Bosch Rexroth (L&S), Hansen, Moventas (Metso), Renk, Winergy These features of the gear oil can potentially help extend equipment life, reduce downtime and lower maintenance costs all of which can help unleash the productivity of your wind turbines and enhance your competiveness.

3 Wind Turbine Gearbox Lubrication Mobilgear SHC XMP 320 is a synthetic gear oil that has been scientifically engineered to perform in demanding wind turbine gearbox applications. The result of a multi-year development program, Mobilgear SHC XMP 320 has been extensively lab, bench and field tested. In fact it was used as the high reference oil during the development of the wind turbine bearing test protocol currently used in the industry. Lubricating a wind turbine gearbox poses many challenges, which have a direct bearing on the lubricant properties. Consider the following: Weight restrictions on the gearbox (compact design; high load and handling capability; case hardening of gears) Demand for extended oil drain intervals Excellent protection against micropitting and wear. Oil performance retention and protection against aging. Use of fine filtration Oil filterability even under wet conditions. Off-shore wind turbines Strong rust protection: wet oil filterability. Changing ambient temperatures and non-permanent operation Capability for wide ambient temperature range.

4 Mobil SHC Grease 460WT Supreme-performance synthetic grease for wind turbines Proven Performance in Key Wind Turbine Applications Mobil SHC Grease 460WT is a high performance product scientifically engineered to exceed the demanding requirements for severe wind turbine applications at extreme temperatures. The balanced formulation profile of Mobil SHC Grease 460WT makes it the compelling choice of grease for the lubrication of main (rotor), pitch (Blade) and yaw (tower) bearings in wind turbines. The slow speed main shaft (rotor) bearing is subject to high loads. The high base oil viscosity of the Mobil SHC Grease 460WT helps to maintain a proper lubricant film thickness to protect the bearing from wear. The low internal friction of the base fluid offers the potential of reduced low temperature starting torque. The Pitch and Yaw bearing move slowly through only a few degrees of rotation, hindering the development of a proper lubricant film. Furthermore, vibrations caused by wind are transferred to the pitch and yaw bearings, which makes false brinelling protection the most important lubricant feature of this application. Mobil SHC Grease 460WT meets industry test standards for fretting corrosion and false brinelling protection, along with excellent rust and corrosion protection. Mobil SHC Grease 460WT allows for the consolidation of main, pitch and yew bearing greases into one product, minimising the risk of re-lubricating with the wrong product. Increase productivity and reduce maintenance costs with this globally available grease for wind turbines.

5 Performance Benefits Wide application temperature range -40ºC up to 150ºC Excellent false brinelling protection Outstanding structural stability in the presence of water Excellent protection against rust, corrosion and wear. Mobil SHC Grease 460WT combines the unique features of synthesized hydrocarbon-based fluids with those of an advanced lithium complex thickener, which contribute to excellent low and high temperature performance, structural stability and resistance to water. A carefully selected propriety additive system provides features such as excellent wear protection, and rust and corrosion inhibition. The low internal friction and high natural viscosity index of the base fluids offer the potential for low temperature starting and running torque, and excellent low temperature pump ability. Additional benefits include enhanced grease and bearing life, a wide operating temperature range down to -40ºC and the suitability for use with either manual or centralised greasing systems - with the overall aim of helping to reduce maintenance costs and improve profitability. Preferred By Equipment Builders Worldwide Mobil SHC Grease 460WT is recognised and appreciated for its innovation and outstanding technical performance around the world. Mobil Industrial Lubricants, work with Original Equipment Manufacturers during product development to ensure that the products provide exceptional performance in continually evolving industrial equipment designs. Mobil SHC Grease 460WT is recognised by many builders of wind turbines and wind components and has become the first fill product of choice.

7 Sage Oil Vac Pump Chemical Corporation believes that the method used to deliver lubricants to a wind turbine gearbox or hydraulic system is just as important as the quality of the lubricant itself. And without the use of specialist pumping equipment such as a Sage Oil Vac pumping unit a products integrity and cleanliness levels could be easily jeopardised during the oil exchange process. By using a Sage Oil Vac pump system to deliver the products, Chemical Corporation can ensure that the products being delivered to the wind turbine gearbox or hydraulic system are at their optimum level for both product integrity and oil cleanliness levels. When combining this level of product delivery protection with Chemical Corporations pre-delivery product filtration system, each Sage Vac Pump unit will offer customer s better overall protection of their equipment, less downtime during oil exchanges, guaranteed product cleanliness levels to DIN ISO 4406:99, increased productivity and improved profitability.
