Plastic Archimedes Screw Generators

■ All the benefi ts of existing Archimedes Screw technologies. ■ Suited to heads of 1-4m with fl ows of 300-900l/s (greater in parallel

operation. ■ Durable toughened plastic Triple Helix: lightweight, non-corroding,

economical. ■ Potential to generate 25Kw/screw @ 75%+ water to wire effi ciency. ■ Turbine manufactured in UK, easily transported and installed with

minimal civil works. ■ The screw itself is integral with the outer cylinder and the whole

assembly rotates together, as a result no water is lost and a greater amount of available energy is generated.

■ The screw is supported on a central shaft which rotates on bearings on a simple chassis fi xed at 22˚. This chassis carries the generator and stepup gearbox.

■ The chassis is mounted on four fi xed points that are installed to channel fl oor.

■ The screw is supplied with a regen drive and control system to harvest the generated energy in a safe and controlled manner.

Water only flows through the lower half of the turbine, forcing the turbine to turn in order for the water to reach the lower level.

Water enters the turbine via the automatic sluice gate. This sluice gate governs the flow through the screw and protects it from overloading.

The powerhouse contains the generator, gearbox and sluice control equipment. The control panel gives an up-to-date reading of the total power output of the screw and allows automated control of the plant.
