FlexStream
FlexStream is an efficient and tough crossflow turbine optimized for medium-head sites.
FLOW: 10-100 CFS | HEAD: 50-100 FT.
Updated design
The FlexStream turbine is an evolution of a traditional crossflow design. It includes an optimized guide vane and blade geometry to maximize efficiency. The inlet guide vane on the FlexStream is optimized to provide the best relationship of efficiency and flexibility at off-design flows.
Technical features
INLET GUIDE VANE
Engineered inlet vanes improve efficiency and allow for efficient operation at a wide range of flows
GUIDE VANE GOVERNOR ARM
Adjusts based on head and flow measured at control panel
PRESSURE CASING
Ogee contoured pressure casing enhances efficiency by improving both the free stream energy capture and the reaction energy recovery passing through the draft tube
TURBINE RUNNER
Optimized runner geometry improves overall efficiency
