Since ancient times, the hydropower screw has been known as an "Archimedean screw." The key factor is that the reversal of its function provides an efficient means of saving energy.

The REHART GROUP hydropower plants are exceptionally cost-effective, due to their price-performance ratio compared with more powerful but very expensive turbines; their efficiency is also significantly better than turbines and conventional water wheels, especially when operating with partial loads. Even minimal potential for hydropower can thus be exploited in this way.

We are able to process from 3.5 to 350 cfs with a screw diameter of 16.5 feet. Our designers can design REHART hydropower installations to meet customers' requirements with either three or four gears.
