Empowering clean energy. Ensuring quality.
Our responsibility
At ConverterTec Aftermarket & service, we take responsibility for the environment, for our people, and for every product we deliver. Our mission goes beyond maintaining converters: we actively support a cleaner energy future, uphold the highest standards of quality, and create a positive impact on society. Every repaired or upgraded converter helps extend asset life, reduce resource consumption, and support global climate goals for a greener, safer, and better tomorrow.

Frequency converter service
for a green energy future
We see our services as a key pillar for a truly sustainable energy transition. Wind energy is inherently clean, but real sustainability extends far beyond installation, it lives in every repair, upgrade, and maintenance decision.
Extend lifecycles
We keep frequency converters and wind turbines operating longer, reducing waste and saving valuable resources.
Support the circular economy
Through repair, refurbishment, and component reprocessing, we minimize raw material use and environmental impact.
Improve efficiency
Smart upgrades enhance performance, lower CO₂ emissions, and maximize energy yields even in challenging conditions.
Ensure reliability
Predictive maintenance prevents major failures, reduces downtime, and keeps clean wind power flowing consistently.
Quality without compromise
We take deep responsibility for the quality of every product, spare part, and service we deliver. Our commitment is backed by ISO 9001 certification and proven through extensive in-house testing that ensures safety, reliability, and long-term performance. From precise manufacturing to thorough refurbishment, every step is carefully controlled and continuously improved by our experienced specialists.
