Pressure maintenance systems up to 10 MW with pumps
Pneumatex Transfero T_ is a precision pressure maintenance device up to 10 MW with pumps for heating, solar and chilled water systems. Its use is particularly recommended where high performance, compact design and precision are required. In the medium performance range with tight budgets, they can also be used as combination devices with integrated degassing and water make-up.
