A Real Alternative to New Parts
Today, the control, guidance, and monitoring of wind turbines, down to individual components and complete systems, are largely managed by advanced electronic systems. We group all of these functions under the term control electronics. With ongoing technological progress, functional expansion, growing complexity, and digitalisation, control electronics have become the central brain of the turbine and its primary access point.
As specialists in the repair of control electronics, we provide an economical and reliable alternative to costly new parts through our refurbished electronic assemblies and in house developments.
The service includes:
Complete overhaul and enhancement of electronic assemblies in line with industrial standards
Εnsuring reliable operation, improved performance, and compliance with industrial requirements.
Functional testing of every repaired assembly in a simulation environment under realistic conditions
Verifying performance, ensuring reliability, and confirming readiness for safe return to service.
A two-year guarantee on all refurbished assemblies
Providing assurance of quality, reliability, and sustained operational performance.
Certified processes in accordance with DIN EN ISO 9001:2015
Ensuring consistent quality management, and adherence to internationally recognized standards.
Supply of electronic spare parts within the scope of full maintenance contracts
Ensuring fast availability, reduced downtime, and seamless integration into ongoing service operations.
Direct sales via our dedicated spare parts department
Providing expert support, and reliable access to certified components.
