We make quality our philosophy

Over time, we want Stefani to be recognised for the quality of its products.

The most important certification that we offer our customers is this principal objective: to work on the market to ensure our company of an identity closely linked to quality. This commitment is expressed in a new product range that is outstanding for performance and strength.

The use of raw materials and components of the highest quality, the scrupulous control of the production process and material traceability are only some of the elements that guarantee the quality of our products and enable us to offer a three-year guarantee air heat exchangers on the entire new range. The inspections carried out on heat exchangers envisage both internal and external tests, entrusted to the most authoritative and accredited international laboratories.


In recent years, we have engaged in a systematic change of mindset in relation to safety, quality and environmental policies, which has required major investments in certifications and staff training. Thus, in 2018, we obtained ISO 9001:2015 Quality Management System Certification and, in 2021, ISO 14001:2015 Environmental Management System and ISO 45001:2018 Health and Safety Management System Certification.


Our heat exchangers comply with the most stringent standards and certifications and follow a strict ethical and commercial policy. The exchange geometries of the new Stefani range are tested and certified by TÜV, to ensure the best guarantee of quality and the total reliability of performance.
