Replacement and Refurbishment Services

Upgrade your existing hydro system

Replacement runner and needle valve for a 6,100kW project in Montana.

Canyon Hydro applies this same attention to detail for customers needing replacement components for existing systems.  Within the constraints of existing powerhouses, turbines, nozzles, and generators, Canyon Hydro engineers will design and retrofit the new components to deliver the highest possible efficiency.   

Three-dimensional models are created from CAD drawings, laying the groundwork for patterns and castings.  Runner castings are tightly controlled, following rigid specifications for alloys, chills, core assemblies, and other requirements.  Before the runner is released for final machining and balancing, it undergoes non-destructive testing and heat treating. 

Our goal at Canyon Hydro is to build replacement components that deliver more power and last longer than your originals.
