The Nautilus CMC Medium Head (CMC-MH) style turbine has been produced in the U.S. since the early 1900’s. This simple regulated Francis turbine is designed for heads of 3m to 12m and develops a maximum electrical output from 1,900 watts to 9.2 kw, depending on available head.

The Nautilus T Medium Head turbine has been manufactured for over 10 years. Many of these turbines are installed in the U.K. and the United States. The hydraulic design is based on a utility grade Francis turbine that is reduced in size and fitted with a trapezoidal section scroll case.
