55 years of technology in the research and production of air conditioning systems


We consider “love for the climate” (environment, people, relationships, collaborations) to be our path to excellence.

Apen Group is a leading company in the construction of heating and air conditioning systems that’s been operating in the air conditioning sector since 1967.

Established under the name of Thermovür, with the specific purpose of building eco-friendly burners and civil and industrial heating equipment, in 1973 the company was joined by AERMAX, a leading producer of heaters.

In 1991, the companies Thermovür and Aermax merged, giving rise to what is now known as APEN GROUP SPA which stands for “Gruppo di Aziende Per le Energie Nuove” (New Energy Company Group).
