Service: It’s more than just a face.

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:

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.

You respect the power of the wind – whether you operate one turbine or an entire wind farm. And you know from experience not to underestimate this power. Good wind sites in particular pose tremendous challenges in terms of materials and equipment, especially for the baseframe. As the backbone of your WTG, it is exposed to enormous shear forces and bending moments. They can push the materials used in virtually all types of WTGs – not just older units – to their outer limits and beyond.

The result: Cracks or unstable weld seams on the baseframe. Repairing them is highly labor-intensive. Unless, of course, cracks are identified in an early stage. With our extensive experience and profound expertise in WTGs, we know the importance of assuring baseframe quality so you can restrict the wind’s impact to exactly where you want it: On your bottom line.

Experience: More than just a supporting role

Two paths, one destination: Baseframe quality assurance.1. Needs-based maintenance on a case-by-case basis. With needs-based maintenance, we come whenever you call. We will visit your site as soon as you call us or discover a crack or any other issue with your baseframe. We will analyze any damage and repair it at your request. 2. Maintenance throughout the WTG lifecycle. We sign a contract agreeing to perform all the services required to inspect and repair cracks, no matter how much time and effort this may entail. You delegate: A lot of responsibility. You gain: A sense of security. After all, our maintenance covers the entire lifecycle of your WTG.
