On 22.01.2026, we were able to successfully complete the QM audit at Frei AquaService AG in accordance with the ISO 9001:2015 standard of the SQS - Swiss Association for Quality and Management Systems.
Many thanks to our auditor Dr. Dirk Bongert for the professional, constructive and appreciative audit.
We would also like to express our special thanks to all the employees involved, whose commitment, preparation and expertise made a significant contribution to the positive result.
Passing the maintenance audit not only confirms our existing processes, but also motivates us to continue developing our quality standards in the future.
