Quality is behind your success and our success

For us, quality means that investors as well as planners and users fulfill their standards and requirements.

Our quality assurance system and our quality management is reviewed by approved auditors from ZDH-Zert annually.

We are a certified company according to DIN EN ISO 9001:2015 and therefore guarantee consistent quality to fulfill your requirements.

HVAC association of producers

As a member of the HVAC association of producers, we bring our competencies into the rulebook of HVAC regulations. These openly accessible regulations interpret the current legal situation in each case and create safety and transparency for our customers.

Energy labeling

Our design software has been certified by TÜV-Süd (technical control board) for determining the energy efficiency class according to the HVAC regulation 01.

Even in the future, we will not only meet our obligation for a classification, but will have the method for determining the efficiency class reviewed and certified by an independent body.

Environmental labeling

By adhering to Directive (EU)1253/2014, we support the achievement of the EU climate protection goals. We constantly strive to reduce energy consumption during production as well as during the operation of the air conditioning units. We pay special attention to the energy consumption during the operation of the systems, since the greatest savings potentials lie here in the long run.


Since Summer 2020 we are Eurovent certified.

Also with this step we ensure our continuous quality improvement.
