root cause analysis

our laboratory enables you to gain insights. we are setup the measure and analyse characteristics of IGBT modules and stacks as well as general electrical circuits. whether you are in need to replace a component or looking for an expert's opinion, krecotec has a solution for you. 

in-house lab testing, analysis and evaluation

Your Independent Experts in Converter Technology

 

At krecotec, we bring together decades of hands-on expertise and cutting-edge measurement technology to ensure one thing: faults aren’t just detected – they’re resolved for good.

 

We deliver independent, manufacturer-agnostic analysis that fits seamlessly into your project workflow. No matter what hardware you use, our solutions adapt to your needs – not the other way around.

 

From Vestas, Siemens Gamesa, and Nordex to Repower/Senvion, GE Vernova, Fuhrländer, and beyond – we diagnose issues across all major frequency converter brands. Our broad, cross-manufacturer experience enables us to spot both recurring fault patterns and rare, elusive anomalies – with speed, precision, and complete transparency.

 

Our approach goes far beyond standard testing: we map fault paths from root cause to final effect, giving you a rock-solid foundation for decision-making. And we don’t stop at the report – we design practical, alternative solutions to cut downtime, streamline processes, and prevent future disruptions.

 

Need a full replacement? We’re by your side from planning and procurement to commissioning – always with an unwavering focus on long-term reliability and operational safety.

 

With krecotec, you gain more than just measurement results. You gain clarity, confidence, and tailored solutions that keep your systems running – and your business moving forward.
