wind turbine gearbox (WTG)

 
System
The gearbox is the heart of the wind turbine, converting low speed from the rotor shaft to high speed on the generator side. The complex gear and bearing design is sensitive to particles and moisture. Combining high viscosity lubricants (ISO VG 320), high loads on components and harsh environments, make it even more crucial to keep the WTG oil clean and dry.

Challenge
If the WTG lubricating oil is not kept clean and dry, you risk very expensive repairs or replacements, down time and possible penalties for not delivering power to the grid. Furthermore, contaminated oil cannot achieve a long life-time, so the oil may need to be replaced prematurely. Long oil lifetime can only be achieved if water, wear particles and oxidation products are removed from the oil continuously. In terms of servicing the oil filter, the often remote locations of the turbines result in high costs for replacing a clogged in-line filter insert outside of normal service routines. 

Benefits, installing CJC® Oil Filters

• Protect your investment
• Optimise availability and uptime
• Reduce risk of expensive gearbox repairs
• Reduce risk of unplanned breakdowns 
• Reduced maintenance costs
• In short: protect your asset and optimise your LCoE

When you install a CJC® Oil Filter solution on your gearbox, you get the oil filter with the highest dirt holding capacity, suitable for the normal service intervals, so you do not need to service any oil filters untimely. CJC® Oil Filter is known for keeping oil clean, dry and without oxidation products, which is documented over many years in several thousand WTG installations. When you choose CJC® Offline Oil Filter, you ensure a long lifetime of the gearbox and the lubricant, you reduce maintenance and you avoid unplanned breakdowns. And you can even remotely monitor the condition of your system using the CJC® Oil Contamination Monitor, OCM15.
