This year it was not only a so-called surveillance audit, but also a recertification audit, as it takes place every 3 years and is therefore even more important.

We successfully passed the recertification audit – conducted by DVGW CERT GmbH!

Our primary goal is satisfied customers: For this reason, we continue to commit ourselves in the form of
DIN ISO 9001:2015 to perfectly fulfil expectations with regard to quality, service and delivery reliability.
