About

Stilmas traces its roots to 1912, when engineer Giovanni Mascarini founded a company built around patented industrial steam systems. The Milan-area business became Stilmas in 1969 and is now known for carrying that engineering tradition into clean-water technology for pharmaceutical, biotech and advanced-technology customers, with more than 100 years of experience and installations on three continents.
