Boscarol Cryogenic Economisers and reducers
Boscarol has developed two product lines to manage pressure differences and surpluses, creating solutions that allow on the one hand to make the plant more functional and efficient, and on the other hand to ensure greater safety and financial savings.
Sensitivity, precision, consistency
Boscarol economisers are a guarantee of safety and financial saving. They stop the risk of surplus elimination in case of overpressure and leakages in case of temperature increase, which are typical for plants without economisers.
- Restoration of normal pressure values
- Surplus recovery at its natural location
- Losses go back into the use cycle
- Plant safety and economy
Boscarol reducers convey fluids directly into the service, regulating the different inlet and outlet pressures. The working section of the diaphragm is fourteen times larger than that of the shutter: such a ratio allows to obtain a very sensitive, precise and constant overflow opening and to respect the pressure value established downstream.

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.
