Ampair UW Underwater Hydro 12/24V
Underwater (UW) 100 micro hydro generator
A submerged generator for fast flow zero head streams.
The UW100 is a submerged generator designed for charging 12/24-volt battery systems from fast flowing zero head streams. Strictly speaking it is a picohydro generator ideally suited to:
Yachts.
Navigation Buoy.
Water Supply Monitoring.
Remote Homes.
Aquaculture.
This unit stands out from the crowd in submerged generators.
Can be used with equal success on a yacht at sea or on land in fast flowing rivers, mountain streams & water pipe systems.
The UW100 offers the opportunity to generate up to 2.4kWh per day from any 400mm deep (15") fast flowing stream. When the stream flows at 8-knots (7mph; 15kph) the UW100 will produce 8 amps continuously, and when the stream flows at 6-knots (5mph; 10kph) it will still produce 1.5kWh per day. And remember that a stream can be diverted into a narrow culvert to increase flow rates.
Technical specs.
Starts charging at flows below 1m/sec (2 knots) - generates up to 8amps at 12v.
Proven to depth of 10m.
All water joints (mechanical & electrical) are double sealed.
The oil filled housing has a pressure expansion chamber to allow operation at intermediary depths & in all temperatures.
UW 100 technical description
The UW 100 is a submerged water powered generator for 12/24 volt 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 100 features low waterspread cut-in (1½ knots) and a high charge rate (8 Amps) without sacrificing space for weight. The body is filled with hydraulic fluid to eliminate corrosion and to equalise temperature-induced pressure changes.
The forward facing 3 bladed propeller drives a permanent magnet alternator producing up to 8 Amps output current for a 12 volt system. The shaft rotates in double seals for optimum protection, backed by twin O-ring static seals at the rear of the casing. The cable exit is similarly double sealed by an internal moulding and external gland. The alternator body is filled with hydraulic fluid to eliminate corrosion and to equalise pressure changes caused by ambient temperature.
UW100 electrical information
Four metres of 4-core cable connects to two external rectifiers fixed on a heatsink which should be mounted in a suitable dry location near the battery. The output control switch and fuse are wired in the DC battery line. Any connector in the AC cable needs 4 individual contacts.
Propellor options
There a variety of different propellors available in production with the following three menu choices:
Shrouded or unshrouded
Shrouded propellors should be slected whenever the water may contain rope or fishing line fragments, fine weed, or plastic debris.
Clockwise or anti-clockwise rotation
Normal propellors rotate clockwise. The anti-clockwise version is to balance towed buoys with twin underslung units.
Standard pitch or coarse pitch
Standard propellors are ideal for low speed start-up (1.8-knots) and thereafter produce approximately 1-amp per knot. Above 8-knots (4 metres/second) the coarse pitch (low RPM) propellor should be selected. This also reduces propellor drag at low speeds which is useful for racing yachts.
Standard, clockwise, unshrouded
Coarse, clockwise, unshrouded
Standard, clockwise, shrouded
Standard, anti-clockwise, unshrouded
The cable exit is similarly double sealed by an internal moulding and external gland. The alternator body is filled with hydraulic fluid to eliminate corrosion and to equalise pressure changes caused by variation in immersion depth and ambient temperature. A reservoir in the end casing allows expansion and contraction of this fluid
.
If you are measuring the speed of your stream, you should do so at the proposed location of the hydro. If you are timing a floating object being swept along by the current you should use something that is mostly submerged (like a block of wood) rather than something that only skims the surface of the water, such as styrofoam.
