BESPOKE WATER TURBINES
(for power outputs up to 1500 kW)
The ‘Allstream’ range of bespoke turbines encompasses all those projects that do not fit within our ‘Mainstream’ modular range or within our ‘Powerstream’ water-motor range. These projects are either large enough to warrant a special design or require original innovations.
For projects with outputs over 50 kW and up to 1500 kW we would offer a ‘bespoke design’ because even small improvements in performance gained by matching the site exactly, will pay for themselves is a very short time.
Evans Engineering is one of the few companies that can design and manufacture one-off turbines for unusual or research projects. Listed below are some of the many different projects that we have handled over the last 35 years.
For power outputs between 50 and 1500 kW
For special liquids and applications
By its nature this is an area that is undefined and often associated with an R & D or restoration project.
THE OPERATING HEAD has ranged from the first 'Tidal Stream Turbine' in the UK where the kinetic head is less than half a metre, to a record 1000 metres of head for a batch of small turbines for offshore applications in the Middle East.
THE TEMPERATURE of the operating fluid has ranged from a low of â€“1000C (liquid CO2) in a prototype refrigeration system, to a high of 500C and ph 9 from a hot soda spring in Africa
THE SIZE OF TURBINE has ranged from a minute 12 mm diameter to the 3.5 metre turbine above that is a model of the real thing at 15 metres.
A SELECTION OF TURBINES manufactured to customers specific requirements are shown below.
