The continuous training system that has made our team unique in Europe

Our system is based on the continuous training of staff, structured in a multi-year course of theoretical-practical studies, carried out both in the classroom and in our exclusive Alisea Training Center, where all those systems are installed that our technicians then face in the everyday activities.

Over the years we have given life to a training course, a real Master in Aeraulic Hygiene, articulated on six increasing levels of professionalism, achievable in a minimum period of five years.

The pillars of our working method are continuous training and technological innovation,
that we have always pursued to continue solving critical issues and to overcome new challenges.
