FG Desiccant breathers in wind turbines

Wind turbines make an indispensable contribution to environmentally friendly energy supply and climate protection worldwide. The more efficiently the turbines operate, the better the energy balance and operating economy. Filtration Group Industrial’s customer, an industry leader in the USA, is committed to sustainability and consolidation of energy from renewable resources. The customer produces energy for nearly 100,000 homes at its corporate facility in Michigan. Based on a comparative study, aeration dryers from a wide variety of market competitors were tested in a wind turbine over a 90-day period. These included Filtration Group Industrial’s TT-4-CV aeration dryer with check valve.  

Challenge

Gears are an essential component in the process of power generation from wind turbines and must be adequately lubricated with well-maintained lubricating oil. Without smooth operation of the primary gearbox, wind energy cannot be converted or efficiently transferred to the power plant of any turbine. If the correct lubrication techniques are not followed, such as monitoring the service life of the lubricating oil, which prevents damage to rotating gears, the efficiency and service life of the oil will drop rapidly. The result is excessive wear on the gears, requiring more frequent replacement of system components. In addition, poorly maintained lubrication increases friction in the drive train, reduces power transmission efficiency and increases operating costs.

INFO

Maintaining transmission oil quality is a challenge given the often dirty operating environment.

Solution statement

  • At the end of the test phase, the TTI aeration dryer had a 15 % longer service life
  • The TT-4-CV deaerator has absorbed 17% more moisture, resulting in a more sustainable and efficient solution with lower unit costs
  • Due to the open environment, temperature and pressure fluctuations, lubricating oil can quickly be saturated with moisture. TTI aeration dryers have been installed to absorb moisture from the oil and improve oil life.

Customer value

  • Reduction of maintenance costs and process interruptions
  • The small process improvement has a stronger and more positive effect on the daily operation and contributes to maintaining the oil quality
  • Positive results of the study helped TTI Todd Technologies Inc. to win the business with wind turbine operators over its market competitor.
