Prex Pro

Prex Pro was born as a division of SIMMM Engineering and its history goes back a long way. Edgardo Mariani in 1986 from a small office on the outskirts of Milan founded a family business for the marketing of electric motors. Shortly thereafter, he created the first high-pressure pump with a mechanical and engineering vision that was not only innovative but totally different from traditional products. From the Italian market, the company expands to European and world level, selling in all 5 continents. Hence the division that deals with the production of professional cold water high pressure cleaners was born, decreeing worldwide success.
