Azienda Apen Group: caldaie a condensazione e scambiatori di calore

The Company

Since its foundation, in 1967, APEN GROUP has been playing a leading role as a manufacturer of HVAC equipment. Its original name was Thermovür and its main task was to produce environment-friendly burners and equipment for residential and industrial heating. In 1973, AERMAX, a sister company, was created. AERMAX’s aim was the production of warm air heaters.

In 1991 the two companies merged in present APEN GROUP SPA (APEN stands for the Italian of Companies for New Energies).

Environment protection is essential for present and next generations’ quality of life.


Apen Group’s challenge is investing in research and development activities which grant the design and the production of environment friendly products. Such a concern is well resumed in the current slogan “Apen Group caring for environment” and it involves the all company organization: from research of suppliers and partners who share this same goal, to staff personnel, natural source optimization and definition of any prevention control and correction so to respect the fixed quality goals and environment deference.
