AMPAIR UNDERWATER GENERATOR
The Ampair UW is a submerged water powered generator for 12/24 V battery charging. It is a self contained unit, (on-shaft propeller, streamlined housing, sealed alternator with pressure relief chamber), operating to depths of 10m below the water surface. The UW features low waterspread cut-in (1½ knots) and a high charge rate (8 Amps) without sacrificing space for weight.
Propeller options
Standard:
Ideal for low speed start-up (1.8 kt). Charges at approx. 1Amp / kt thereafter clockwise & counter clockwise propellers available, e.g. for twin installations on seismic floats.
Shrouded:
Shroud prevents fine rope or fishing line from winding around shaft and damaging seals.
Low R.P.M.:
Designed for fast flows / high speed yachts. Delays charging and reduces drag until greater waterspeeds are reached.
Micro-hydro battery charging applications
Generates up to 2.4 KW per day from any 400 mm deep fast flowing stream. When mounted in a stream that flows at 15 kph (slow jog), the Ampair UW produces 8 Amps continuously. This represents enough power to supply a typical remote home, independent of the main supply. Even a stream flowing at 10kph will produce 1.5 KW per day and this output can be increased by diverting the flow into a narrow culvert to increase flow.
Applications
Remote cabins
Aqueducts
Water pipes
Barges
Yachts
Any other situation where there is a continuous water flow and zero head.
