Boscarol's sectors
A tradition of flexibility and professionalism
Food, chemical, pharmaceutical, mechanical and much more: the sectors served by Boscarol solutions are various, each one with precise needs that are met by specific products. Production flexibility, competence and high technological performance are the factors allowing us to successfully deal with the most different industries.
Cryogenic gas containment solutions
Our low-temperature valves are designed for all companies that produce technical gases or pressure equipment to contain cryogenic gases, such as the oxygen and medical gas production chain. Reducers are devices whose function is to decrease upstream pressure by regulating it downstream to a lower level, keeping it constant. They are used in various sectors such as the dry ice production.
