Founded in 1879, Zambelli was one of the first Italian companies to manufacture "scientific equipment”.
By distributing its products throughout the country, Zambelli became one of the leading companies in the sector.
In 1954, following in the footsteps of its predecessor, the Officina Costruzione Riparazioni Apparecchiature Scientifiche was founded, giving birth to the current Ocras Zambelli and beginning the production of climatic chambers and industrial ovens.
With the same enthusiasm and passion as its founders, we have acquired the brand to compete in the market of climatic chambers and industrial ovens, strengthened by a consolidated know-how built up over a hundred years of activity..
