The Aermec story initiates with Ettore Riello. Born in 1868, he emigrated to Brazil when in his early twenties.
On returning to Italy he set up Officine Fratelli Riello, a manufacturing company, in 1922. In 1923 he developed his first oil burner for heating applications, marking the entrance into temperature control.
In the late 1950’s the company, since renamed Riello Bruciatori, identified a need to implement seasonal stability within its manufacturing process. Giordano Riello, Ettore’s grandson, identified the ideal if somewhat ambitious solution, the manufacture of air conditioning equipment.
Giordano Riello manufactured his first air conditioner in 1961, creating the Aermec brand in 1963. Consequently Aermec can be considered one of the first, if not the very first, air conditioning manufacturer in Europe.
From here the first to build split units in Europe, the move towards fan coils where Aermec is a world leader, continuous expansion adding the complete portfolio of differing air conditioning product solutions, an ever growing level of internationalization and the creation of Giordano Riello International Group, the group of companies of which Aermec is a part.
