RockyHydro - Affordable Custom Hydroelectric Systems

 Low Head Systems  

Many low head sites will be able to utilize our popular turbine and generator matches.  Some sites may be able to use a standard style turbine but you'll need to gear up the generator, this can be done easily with a set of pulleys.  Our turbines are a step up in technology over a pelton wheel, and can handle more water for their size than a pelton.  Still, for sites with very little head and a great deal of flow, we have several suppliers that utilize reation-style turbines.

Our supplier PS also sells a fantastic low-head system that is a little more versatile than APR, and can handle higher heads and a wider range of flow rates.  The more head you have, the more flow the system requires.  It works better for sites that have a higher head than 5 feet, which is what the APR is designed for.  Advanced models have a self-cleaning system incorporated.
