Bonna Intake Head Solution
PT. Bonna Indonesia designs and manufactures different diameters of Intake Head to fit customer project specifications, site conditions & environment.
The seawater intake structure consists of a large diameter system with equal sized opening windows and connected to the intake pipeline.
