The Nautilus is a Francis-style turbine capable of tremendous power output in a compact design. It will power your home and shop for generations on as little as four feet of head. Water is channeled to the turbine via a Penstock or large diameter pipe. The Nautilus is unique in that it uses both a closed water diversion system prior to the turbine (providing substantial pressure head), while also using a Draft Tube from the turbine to the tail water (producing suction head).
The Nautilus has an expected life of over 50 years. All components are made of laser-cut stainless steel to insure smooth water surfaces that will never rust. Massive taper roller bearings and carbon/ceramic face seals will last 7-10 years between refits.
The Nautilus can be disassembled and easily transported into the most remote areas as no single component weighs over 95 lbs. (44 kg.). The total assembled weight (without the alternator) is under 230 lbs. (105 kg.).
The 8in. runner model can produce from 360 - 3400 watts of power with between 4 - 18 feet of head, while the 10in. runner model can produce from 550 - 2200 watts of power with between 4 - 10 feet of head, depending on flow rates and installation.
The base price for the Nautilus turbine is $10,600.00. This does not include the alternator, controller or diversion, all of which must be sized for your specific installation. Please contact us to order. When you call (or email), please provide the following information for proper turbine sizing: head distance, available flow volume and estimated pipe distance from the inlet/water source to the turbine.
Powerflow Electronic Load Governor: Easily regulate small AC hydroelectric generators up to 5kw. Operates by keeping a steady load on the generator at all times. You only need to install a single dump load element. Can be easily installed at either the turbine end or in the house. Very accurate and doesn’t make the house lights flicker. Rugged and well engineered.
