Archimedean Screw Hydro Turbine – Old Technology New Application
The Archimedes Screw has been used for pumping water for over 2000 years. Applying the principle in reverse, the same equipment now offers a new method for generating power from water, providing a fish friendly and highly efficient alternative to a conventional turbine.
Each Archimedean Screw hydropower system is manufactured to be site-specific, with a choice of three designs – steel trough, closed compact and open compact – depending on which is the most appropriate and cost-effective for each individual site.
Closed Compact – Key Benefits:
- Screw + trough + gearbox + generator are all assembled into a single unit at the factory.
- Civil works on site reduced to a minimum.
- Installation time considerably reduced (approx 3-4 hours)
Open Compact – Key Benefits:
- Manufactured as a self-supporting U-shaped steel construction minimising necessary civils work on site.
- Generator unit is an integral part of the construction, easily accessible via a weatherproof, hinged generator cover.
Steel Trough – Key Benefits:
- Concrete foundation cast in situ.
- Screw is supplied complete with its steel plate trough
- Backed up with concrete after assembly and alignment.
- Optimum clearance between trough and screw is guaranteed.
- Civil works on site are reduced.
Eco Evolution are appointed agents in Ireland of Mann Power Consulting Ltd (UK) who specialise in the Archimedean Screw hydro turbine. The Archimedean screw hydro turbines are suited to low-head sites and are fish friendly.
As pioneers of Archimedean screw generating installations in the UK and Ireland, Mann Power believe that Rehart manufacture the best equipment on the market.
Dear sir or madam,
My name is Lefteris Mitsios and I am interesting in making a small
Hydroelectric plan. I want some information about the hydrodynamic screws. The river on my area which I want to make the project has head 4-5m and capacity 6-8m3/s. I would like the prices of the screw and the generator.
I am from Greece and this system does not exist there, so I would like to make a test system and later expand it because there is much interest in Greece.
If you are interested we can cooperate.
I am waiting for your respond.
Thank you for your time,
Lefteris Mitsios.
Dear Lefteris,
Thank you for your enquiry. I will contact you directly.
Best regards,
Frank.
