A company made of people

Our project involves everyone, from new arrivals to those who contributed to Stefani history.

We work and invest for continuous improvement; guaranteed heat exchange performance means seriousness and I believe we have to be committed to improve our industry standards.

Massimo StefaniPRESIDENT

I agree with the new policy and I believe that production process improvement is just as important as the thermodynamic design of our exchangers. For this reason I dedicate my experience to improving our manufacturing process and product engineering.


At new Stefani we joke about working with the right spirit, but we are serious when it comes to performance: we have decided that we will shortly start the process for obtaining Eurovent certification of our product performance.

Michele BelveratoGENERAL MANAGER

I have always believed that knowledge makes the difference and its application to thermodynamic performance certainly offers us some important benefit, but reliability comes first and that’s why we work hard every day to earn it.


We have designed new software for calculating the thermodynamic performance of our products.
