2. Guenter Kirsten the Ing. Entrepreneur start his own inventions and production in the year 1974. First
with oil injected screw compressors for pressed air and technical- and process gas applications. He
was one of the first producers that used this technology in Germany. At this time many competitors
talk about the oil injected systems like a fashion appearance with no future. From 1981 to 1984
Kirsten start to find out a material and a production process to produce rotors without any
mechanical production by polymer material. At least hundreds of material tests in his own
laboratory with different polymer material. Hundreds of receptions, modifications, filling materials
and ever tests to find out the heat extension, the strength, E-modul of the material and many more.
The best material what was find in this time, also for the use in water injected and water lubricated
screw compressors was Polyurethane as polymer. This material could be used to produce the rotors
and also the negative mould, copied from a steel master rotor. Some of the old licensees use this
material and the technology till now, others make copies of the old Kirsten patents.
From 1985 this first technology go in production to manufactory air ends for oil injected screw
compressors, rotors for blowers, rotors for pumps etc. and start also the tests in the water injected
compressors.
All the established players in the market start laughing about the Kirsten rotors and don’t believe
that it can happen to use this kind of rotors in serial production. Like by many new technologies it
ever happen like this.
Now after more then 30 years, not only the rotors, also the water injected systems with this rotors are
the leader in the market segment.
From 1999 also the rotors was be used for oil free compressors and PEM fuel cell applications in the
cars with permanent magnet high speed motors, by OPEL-GM, Mercedes Benz and Volkswagen.
Now after 30 years I will open a new technology to produce rotors, for all kind of applications, oil
injected, water injected, dry compression etc. Also to produce housing and orbit for scroll
compressors. When you interested to learn more about the new technology and invention contact
me.

7. The Water tradement and cleaning system is the
importants device in a water injected compressor. An
Reverse Osmosis System to clean the drinking water and
fill it in the machine when the water level is low. This is
sure not enough to control the water quality in the
compressor system. The water system is not a closed
system. The air that coming in from the atmosphere bring
a lot of bad ions in the system, the water wash all this out
and now the ions are in the water system. Further the
water ever take ions from the material inside the system,
and try to find balance .
A real water tradement has to messuring and clean
permanently the water system. Only the from Kirsten
patented system can do this and give the absolute security
under all conditions that the water quality in the machine is
around the world the same. 30 years of experience with water
lubricated and water injected screw compressors has shown
the way how to do this. When the water in the compressor
system is regulated between a conductivity from 5 to 10 micro
siemens by 20°C, the system runing under safe conditions,
water lubricated bearings life time will more then 50.000
hours.

9. This are some short info's about the new
developments of water injected and water
lubricated compressors. From the technical
standpoint this machines should be driven by
high speed permanent magnet motors. Only
this type of motor give the optimum in
efficiency, noise level etc. about water or oil
cooling. I have used more then 15 years this
kind of motors in some of my products.
Motors also developed and produced myself.

10. The Maintenance Engineer
The oil in compressed air after
compression will attack
downstream equipment,
causing increased maintenance
requirements and increased
plant downtime
The Financial Manager
Low cost oil lubricated
compressors may look attractive,
But when considering the total
operating costs compared to Oil
free compressors, the extra
investment in a NEW water
injected screw compressor will
easily pay for itself, special when
permanent magnet motors are
used
The Application Engineer
Every application can benefit from
oil free air compressors with total
product safety, lower operating,
and maintenance costs and a
healthier working environment
The General Manager
If you require maximum reliability
and energy efficiency to improve
your total operating costs, The
ZERO EMISSİON SCREW
COMPRESSOR, wıth permanent
magnet motors, provides you with
the optimum compressed air
generation solution
The Safety and Environment
Manager
Breathing oil fumes is definitely not a
good idea and oil Condensate can
damage the environment So why do it
the hard way, when you can do it the
smart way with oil free compressors
The Quality Manager
Do not accept the possibility of
product contamination, and reduced
product quality. Only 100% Oil free
compressors can offer a 100%
Guarantee of Oil Free Air
