ANDRITZ Atro hydrodynamic screw turbinesEfficient, rugged, and environmentally friendly
The facts
Water flow up to 10 m³/s
Head up to 10 m
Efficiency up to 92%
Output up to 500 kW
Fish-friendly
Do you own water rights as an individual,
a company, or a local authority? Then a
lucrative source of energy is available to
you at no cost. Don‘t let this potential
simply run down the drain any longer.
An ingenious idea from Greek antiquity
was the source of inspiration for this tech-
nology: The Archimedean screw made
water flow uphill. The hydrodynamic screw
turns that principle around and uses the
position and energy difference of falling
water to generate power.Head (m)Hydrodynamic screw diameter (m)

Your advantages Rapid amortization thanks to small
investment and low operating costs
High efficiency, even with fluctuating
water levels and low volumes of water
Efficient use as from an output of 1 kW,
even with low hydropower potential
Rugged, wear-resistant, trouble-free,
and durable technology
Self-regulating system that adapts
automatically to the water volume and
mains frequency
Low-maintenance plant that requires
very little cleaning
Operates with coarse screen only (no
fine screens needed)
Fields of application As substitute for waterwheels and
turbine plants
As residual water screw turbine in an
existing spillway or a weir system
At former irrigation weirs
At the clear water outlet from sewage
treatment plants
At the cooling water outlet from ther-
mal power stations
At diversion power plants on flowing
water
Back-filled steel trough (WU)In a hydrodynamic steel turbine with a back-filled steel trough,
the screw turbine body is placed in a concrete structure
together with the trough, and the trough shell is back-filled
with concrete. The drive unit and switchgear are mounted on
a concrete structure. This design provides for maximum oper-
ating reliability with low cost for maintenance and care.
Self-supporting trough (WUF)
In a self-supporting trough variant, there is no need to back-fill
the steel trough with concrete. The lower bearing is mounted
on the trough and the forces are transferred to the trough
structure. The drive unit and switchgear are mounted on a
concrete structure.
Compact system (WKU)In this case, the hydrodynamic screw turbine is placed in a
self-supporting trough. The complete unit is a self-supporting
steel structure with integrated drive unit. The baffle plate is
already integrated into the steel trough, which has an open
top. Thus compact system is secured to strip foundations
prepared by the customer. A central support must be provided
as from a blade length of approximately 11.0 m. The customer
then only needs to provide the inlet and outlet areas for the
screw turbine.
Compact tube screw (WKR)In this case, the body of the screw turbine rotates in a
closed tubular shell. The complete unit is a self-supporting
steel structure with an integrated drive unit. The customer
must provide the inlet and outlet areas for the screw turbine.
Particularly suitable for low heads, e.g. clear water outlet from
sewage treatment plants.
SustainabilityEvery kilowatt-hour generated by a
hydrodynamic screw means around 1 kg
less CO2 polluting the environment. Fish,
other creatures, and floating particles
pass through the hydrodynamic screw
unharmed. What is more, the quality of
the water in deeper bodies of water is
improved thanks to oxygen enrichment.
Fish friendlyIn addition to being very suitable for adapt-
ing the screw turbine and trough to the
natural surroundings, the hydrodynamic
screw turbine also allows fish to pass
through it without coming to any harm.
There is no need for the filter screens
needed in small turbine systems as
protection against floating objects. All
that is required is a coarse screen through
which floating particles and, more impor-
tantly, fish can pass unharmed.
Conclusion by the experts“The efficiency of the hydrodynamic
screw turbine compared to other small
hydropower systems of this magnitude
(turbines, waterwheels) is [...] similar or
better. However, the partial load efficiency
can be considered a special advantage
that still makes very efficient use of the
hydraulic energy available, even at low
inflow volume. This is not easy to achieve
in plants of a comparable size.”

AutomationReliable, economic and safe
Your hydropower plant should operate fully
automatically and reliably without any per-
sonnel present, and you would like to check
the plant status and your power generating
data online on your smartphone?
This is possible both with a standardized
design (compact, premium line) and with a
complete customized solution, e.g. with in-
tegration of the entire weir system.
