A sustainable energy policy, based on renewable resources, will be crucial
to their future. Hydropower is one of the front-runners among such rene-
wable energies.
Wasserkraft Volk AG is one of the leading manufacturers of small and me-
dium-sized HEP systems in the world having made a significant contribution
towards a sustainable future.
In our 30 years of business activity, several hundred small and medium-sized
hydro power plants were manufactured, producing environmentally-friendly
energy in over 40 countries all over the world.
In May 2000, the State-of-the-Art Factory commenced operations. This is
the first large scale factory in Germany which is fully energy-self-sufficient
and operating without any CO2 emissions.
In view of the positive approach to the business development, where many
other business firms suspended their investment activities in the year 2008
due to the international financial crisis, Wasserkraft Volk AG put up a new
most modern and highly efficient production plant with a 4000 m 2 shop
floor.
As a medium size enterprise, our main focus is only Germany as the loca-tion for factories in view of our social responsibility and obligation towards
the country and future generations. Last but not least, a great portion of our
success comes from our highly motivated, dedicated, devoted and com-
mitted work force receiving consistent advance training, education and up-
dating in their respective fields in order to render a reliable and persistent
service to our customers.
We are only caretakers of the
world and its resources that
we pass on to our children.

WKV AG is a medium-sized enterprise
located in Gutach/Breisgau. We are still
small enough to react flexibly to the
needs of markets and customers, but
on other hand large and experienced
enough to achieve something great!
At WKV, you get your complete power
plant, including turbines, controls,
alternators and switchboards, perfectly
adapted to each other, from one single
source.
And that is from A Z
Made in Germany!
Choose water for your
eco-friendly energy
source Choose
Wasserkraft Volk AG!
5
Our principle all from one source allows to react extremely sensibly to the
requirements of our customers of you. Designing of your hydro power
station is performed by experienced engineers in the fields of hydraulics,
mechanical and electrical engineering and control technology. You will not
find another manufacturer in the market that can offer more comprehensive
knowledge and experience in the entire range of disciplines.
Our factory is structured to design and build the complete range of turbi-
nes, generators, switchboards and also electronic controls and accessories.
All manufacturing facilities are located in our plants in Gutach and Simons-
wald in Germany literally brining us to the same vicinity thus granting you
high flexibility, quick service and highest quality.
Last but not least: Where else will you receive such willing, eager and en-
thusiastic personal attention from the founder of the organization himself?

Profitability and environmental compatibility dont have to be contradictory:
Hydro power plants are emission-free. No pollution, no CO2, no problems
with waste, low impact to the surrounding nature.
The long life-time of WKV hydro power plants produces eco friendly
electric energy for generations ahead.
At WKV, conservation of resources begins at the manufacturing stage itself.
Our in-house hydro power station produces electric energy required formanufacturing and also feeds the centrifuges on the heating system.
Electric Surplus energy is fed into the local mains.
Only about 22% of the technica l ly useable hydro
power potential on earth is currently uti l ized. Reap
the benefit from our knowledge and experience to
improve on this s ituation!
Generating sets based on fossil fuels are available at low cost, resulting short
term benefits. However, just considering economic aspects, small hydro
power plants are unbeatable in the long run:
WKV Hydro power plants are not only designed for years but for many
many years under continuous operation, thus granting high profitability
for many decades beyond the payback period.
Water always flows downwards resulting in minimum operating costs.
No friction means no wear and tear leading to low maintenance needs.
Energy price hikes do not bother us.

Continued education and professional training and updating ensure the
latest know how being imparted to the present employees as well as new
recruits providing necessary motivational inputs as well.
All this makes WKV AG your partner of choice for design and production
of your next hydro power plant.
Dont settle for the next best!
Expertise so far is an attribute which can be assumed for a company suc-
cessfully serving the international markets for decades. The consistent
evaluation of performance on the operating power plants has directly
contributed towards this competence.
WKV products are beyond the very best you can get for your money; i.ethe passion for detail that has lived at WKV, leading to a quality assurance
starting in the early planning stage up to the commissioning stage.
Over a period of 30 years, WKV AG has again and again proved beyond
doubt that industrial production and passion are thoroughly complemen-
ting. Hundreds of satisfied customers from all over the world will bear
testimony to this.

Natural conditions of water courses is significantly different. Therefore,
every order demands an exclusive solution. WKV uses four different tur-
bine types to transform hydraulic force into electrical energy:
WKV Pelton turbines
WKV Francis turbines
WKV Turgo turbines
WKV Crossflow turbines.
Each of these turbine types is suitable for a specific operation area: Different
output ratings, various head values, highly unsteady watercourses or high
content of floating refuse. In addition, you get WKV speed controllers, WKV
water level controllers and WKV switchboards. Everything with well-proven
technology made by WKV AG.
WKV offers much more than the adaptation of turbine and alternator to the
site conditions. For example, a complete range of specific runner speeds
allows a perfect alignment to synchronous alternator speeds.
Common for all products: The first-class quality. In our test laboratory, we
have proved this beyond doubt and so far achieved highest efficiencies.
Since the company was founded, a big part of our profit has been re-inves-
ted into research and development. This makes us the forerunner in the
global minihydro industry. We keep our technological lead only by con-
tinuous development.
Do not buy your turbine plant at
a discounter trust in the specialist!

Not everything has to be brand-new.Restoration, renovation and modernizing of existing power plants
7/30/2019 WKV_Turbinen_2010_EN-rev1
27/32
Usually hydro power plants are operated for many decades until the rava-
ges of time will require a basic renovation. Accompanying the renovation,
mostly a reasonable improvement in system efficiency is requested.
Other power plants are damaged by natural disaster, systems have to be
partly or completely cleaned, repaired or replaced. Often, special building
conditions or monumental or archaeological protection rules that have to be
adhered to can significantly complicate the work at site.
Our special purpose machinery manufacture covers turbines including
control system, generators and switchboards. By far, WKV is experienced
and flexible enough to refurbish your power plant for a reliable operation
over the coming decades.

Craftsmanship has a long tradition
in our area. The idea of quality is
traditionally lived and realized with
passion for details. Solid education
and advanced training enable a high
level of creativity, what is immensely
important for any kind of manufactu-
ring of special machines.
We from WKV are combining these
characteristics with most modern
manufacturing technologies resulting
in a cost effective manufacture of our
premium products.
Our great in-house production capa-
city makes us largely independent
from sub-suppliers which allows us
to react flexibly and to realize short
project and lead times.
To work at a place where
others are doing vacation
also this is a motivation
for our colleagues!
