S-type tubular turbine is Available in versions of Horizontal Kaplan, Semi-Kaplan and Propeller, also called S-type horizontal Kaplan, S-type Semi-Kaplan and S-type Propeller. This modern turbine is characterized by high efficiency in a broad band of flow rates. Our S-type tubular turbines are ranging from 3.5 to 25m in water head, 50KW to 15MW in capacity, and 0.4 to 5m in runner diameter. They are thought to be the best selection for exploitation of low head hydro-power resources.

s-type horizontal Kaplan with better machine efficiency is achieved by relative motion of vanes and blades, which is called the double regulation Horizontal Kaplan or horizontal full Kaplan. In the double Kaplan regulation version of the turbine, runner and guide wheel regulation the range of flow rate regulation extends from 20% to 100% of the rated discharge rate, Used primarily at heads from 3.5m to 25m. This turbine is therefore suitable for certain run-of-river generating stations where the river flow varies considerably. Installation is almost exclusively with a direct connection to the generator
