Initially, the company manufactures electromechanical devices and, since 1896, undertakes the manufacture of "air agitators" (today's fans), previously imported from the United States, becoming in few years one of the leading companies in the sector, in the World.

 

On 28 February 1900 the sole proprietorship becomes a limited partnership and in December 1905 the company opened in Sesto San Giovanni a great facility, served by the tramway Milan-Monza-Sesto, where employs skilled labor from Milan and unskilled local workers.

 

Here the company produce, in addition to fans, small electric motors, centrifugal pumps and transformers.

 

Between 1906 and 1911 people employed rose from 500 to 1,500, half of them young women involved in the "winding up" engines.

 

In 1920 the company changed its name, becoming joint-stock Limited Company and in 1922, with the death of Ercole Marelli, is inherited by his son Fermo.

 

At that time  was elected as Chief Executive Officer, Antonio Stefano Benni, who collaborated with Ercole Marelli  since the beginning, who directs the Company until the second world war.

 

With Benni direction the company marks a major turning point in financial policy and production.

 

The core competence of our company lies in the production of hydro-generators. Harnessing Hydro Power is where we consolidated our specialization and for decades we have produced highly reliable and efficient machines. From Hydro Power we then expanded and diversified our business units to include other sectors in the field of renewable energy.
