ANDRITZ Atro hydropower screw as a turbine

ANDRITZ Atro invented thehydropower screw 15 years agoThe genius principle is turnedaround

The hydrodynamic screw is

placed inclined in flood directionin the riverThe water flow makes the screwrotating.The energy is given toa generator via a gearbox

Pumps as Turbines Series ACT / FPT / HPT Applications

Island stations for mountain refugees

Drinking water turbines

Waste water turbines

Reserved flow turbines

Micro power stations with supply to grid

Energy recovery turbines in industrialapplications

Small pump storage power stations



19/25

Our philosophy:

Use only in applications, where pump fits perfect as turbine !

Wear resistant execution

Little and easy maintenance

Impeller with large free passage

Low problems with clogging

Direct- or belt drive / gearbox possible

Serial production, short delivery time

Disadvantage: Pumps have only one optimum duty point

AdvantagesPumps as Turbines Series ACT / FPT / HPT

Control of turbinePumps as Turbines Series ACT / FPT / HPT

Casing works as rigid guide vane,only one optimum point available Control possibilities:a) Throttle controlsurplus flow: by-pass

b) Variable speed controlshifts optimum efficiency point
