Ser vice: It’s more than just a face. The perfect starting point: Gearbox position monitoring.

We believe that face-to-face contact and communications will lead to the best solutions for your needs. Being OEM independent, we will always be upfront and open about any defects in your wind turbine. Honest. Fair, and personally. Ingo Daniel and his team look forward to hearing from you by phone or e-mail: Phone: +49 (0) 5971 8025-210 E-mail: windservice@availon.eu

Save the yield. Kidney loop filtration and other upgrades for GE® WTGs (1.5 MW).

Movement is not always a good thing. This is true, in particular, if the movement relates to the drive train of your WTG. Where fracturing of the main bearing remains undetected, the gearbox itself moves up to 9 mm towards the rear. In axial direction, this movement is restricted by the pedestal bearings. This is where the loads of the drive train is applied on the planet carrier bearings and therefore on your wallet. The loads will damage the planet carrier bearings and therefore the entire gearbox. To ensure that the situation does not reach such a serious level, the position of the gearbox can be permanently monitored using two inductive proximity switches. If the position changes, a fault message is sent to the remote monitoring center immediately. The turbine will be automatically stopped and you always stay one step ahead of any movements with serious consequences.

itoring: Advantages of gearbox position mon age • Prevention of serious gearbox dam box position • Permanent monitoring of the gear ches swit by two inductive proximity ine controller • Permanent connection between turb and remote monitoring center of fault messages • Automatic stop of the turbine in case

We tailor our quote to your needs. You can expect the contract we offer you to be upfront and open, too. We believe that contracts are about trust. That is why we carefully adapt our services to your needs. From flexible service modules to complete maintenance contracts. Visit www.availon.eu to learn more.

Permanent quality: Kidney loop filtration.

Gearboxes are often like life itself, with important inner values. In this particular case these values relate, to the oil, as it is one of the most decisive factors for the service life of a gearbox. The design of many systems does, however, only allow a filtration of particles and oil aging products from a size of 10 μm onwards. And it is precisely for these systems that we have developed kidney loop filtration.

Clear competence and clean oil.

The compact pump and filter unit siphons the oil from the lowest part of the gearbox. The oil is then cleaned in the unit and returned to the gearbox. Particles of 3 μm and greater are removed and the moisture dissolved in the oil is absorbed. The additives, on the other hand, remain dissolved in the gearbox oil. This ensures a constant flow of high-quality oil instead of expensive payments for frequent changes, as intervals can be extended to over 60 months.

Although a major component like the gearbox is large and tangible it is, however, difficult to detect when potential problems are about to occur, as these often start, hardly noticeable, at minute levels. Problems can be caused by particles suspended in the gear oil, which at 0.003 mm are hardly larger than bacteria, tiny metal particles or movement of the gearbox by only a centimeter which can cause total failure.

A real plus below zero: IceFree sensors. Sub-zero temperatures don’t affect gearbox fluid. But they do affect components outside of the nacelle. Anemometers and weather vanes will ice up quickly, even at temperatures around the freezing point. That only leaves two options: Call in a service team or hope for better weather. Both options take time. All the while, the sensors register wind speeds of 0.0 m/s – with disastrous consequences. The WTG stays idle due to the incorrect reading and produces no energy despite the wind. It is not unusual to lose up to 5,000 euros per turbine and winter season. But there is a solution: IceFree sensors offer a proven heating system that that can withstand even extreme sub-zero temperatures.

ors: Benefits and features of IceFree sens ance 230V heating • Weather sensors with high-per form s from icing up • Prevents anemometers and wind vane even in extreme • Ensures normal operation of the WTG temperatures

Considerable experience is required to detect the first indications and act accordingly. Availon has this experience and uses it to develop upgrades that prevent serious damage and, among other benefits, considerably increase the service life of the gearbox. Kidney loop filtration ensures that there is no “sand” in the gearbox but, instead, clean oil at all times.

Advantages of kidney loop filtration: • Potential longer oil service life due to effi cient cleaning of the gear oil • Removes oil aging products and particles

from 3 μm onwards • Inter vals between gear oil changes can be decreased to 60 months and more • Additives remain dissolved in the gear oil

and +60 °C • Temperature range between -40 °C ble-screened stainless • High mechanical stability due to dou steel ball bearings (anemometer) ally dampened wind vane • Maximum accuracy due to magnetic • System tried and tested worldwide
