Gilkes are the leading hydroelectric turbine manufacturer in the UK for projects up to 20MW
HEAD RANGE: up to 1000m
POWER OUTPUT: up to 20MW
The Pelton Wheel maintains a high efficiency over a wide flow range. Whenever possible two or more jets are specified. This increases the high efficiency flow range. Every Gilkes turbine is selected and optimised to your site conditions in order to provide the best annual energy production figures.
Pelton turbines are medium to high head free jet impulse turbines. The jet(s) strike the splitter edge of the double bucket and is turned through an angle of nearly 180% before falling under gravity into the discharge channel or tailrace.
Gilkes' Pelton turbines are supplied as horizontal single and twin-jet units or vertical 3, 4 or 6 jet units.
Twin or multi-jet units are specified to increase the flow range over which high turbine efficiencies can be obtained.
Gilkes Pelton runner designs have been continually improved over many years to be amongst the most efficient available.
It is possible to use one size of Pelton bucket on a range of different mean diameters. By this means the turbine can be designed to operate at maximum possible efficiency for any given set of site conditions.
