Cink-Hydro - Crossflow Turbines
Designed according to a turbine technology from 1903 and developed for the needs of modern power plants. Tailor-made for every installation, applicable to run-of-the-river projects, dams, drinking water systems, wastewater treatment plants or to remote, isolated-operation projects. Minimal civil works, easy to install, long service life and almost maintenance-free. No complex spare parts needed.
Flexible, robust, efficient, easy to install and easy to maintain technology capable of processing even the lowest partial flows.
Radial, impuls-type and slightly overpressured turbine with tangential injection of the runner blades and with a horizontal shaft.
For projects with variable flow, inlet of Crossflow turbine is divided into 2 cells of equal or different sizes. That way, high efficiency across the entire flow range is secured. As a result, Crossflow turbines are able to efficiently operate with 10% to 100% of design flow and start operation with just 6% of design flow.
Due to its construction, the Crossflow runner is able to clean itself automatically when spinning. Any object that enters the area of runner blades is pushed out by centrifugal force with each runner spin (each revolution). The object then ends in the tail race and back in the river.
Low-head Crossflow turbines have the efficiency up to 84%. Bigger or higher head Crossflow turbines reach the efficiency of 87%. Thanks to the divided inlet of 2-cell Crossflow turbines, the efficiency stays almost the same across the entire operation range (from 10 to 100% of design flow).
