Quality & environment


Be it cogeneration units, rail vehicles, commercial vehicles or refineries and chemical parks, engines and systems are expected to deliver absolute quality and run reliably.

As an expert for engine repairs and industrial services, we are familiar with the high standards of our customers. To guarantee the uncompromising quality of our products and services, and to continually adapt to the growing requirements of the market we have implemented various quality management systems.


The DIN EN ISO 9001:2008 standard helps us to continually improve our production processes. We define the work steps and test methods for our repairs in our documentation  and re-examine them during every re-certification procedure. The expertise and responsibility of our employees are the most important factors of success for our work, so that training courses are a prominent feature of our quality management system. And, of course, we also commission independent third parties to accompany and monitor this process.



All engines are repaired in line with the latest technical and professional standards at Bücker + Essing; for instance the RAL quality seal for engine repairs. As a member of the quality association of engine repair companies, Bücker + Essing guarantees that all engines are processed in line with the quality and test conditions RAL-GZ 797. The quality criteria not only define the necessary work steps, but also the employee qualifications and technical equipment including high-quality machines and tools.



Bücker + Essing has been certified for wire and powder flame spraying by Germanischen Lloyd.
