� Guenter Kirsten the Ing. Entrepreneur start his own inventions and production in the year 1974. Firstwith oil injected screw compressors for pressed air and technical- and process gas applications. Hewas one of the first producers that used this technology in Germany. At this time many competitorstalk about the oil injected systems like a fashion appearance with no future. From 1981 to 1984Kirsten start to find out a material and a production process to produce rotors without anymechanical production by polymer material. At least hundreds of material tests in his ownlaboratory with different polymer material. Hundreds of receptions, modifications, filling materialsand 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 lubricatedscrew compressors was Polyurethane as polymer. This material could be used to produce the rotorsand also the negative mould, copied from a steel master rotor. Some of the old licensees use thismaterial 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 screwcompressors, rotors for blowers, rotors for pumps etc. and start also the tests in the water injectedcompressors.

� All the established players in the market start laughing about the Kirsten rotors and don’t believethat it can happen to use this kind of rotors in serial production. Like by many new technologies itever happen like this.

� Now after more then 30 years, not only the rotors, also the water injected systems with this rotors arethe leader in the market segment.

� From 1999 also the rotors was be used for oil free compressors and PEM fuel cell applications in thecars 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, oilinjected, water injected, dry compression etc. Also to produce housing and orbit for scrollcompressors. When you interested to learn more about the new technology and invention contactme.

The Water tradement and cleaning system is theimportants device in a water injected compressor. AnReverse Osmosis System to clean the drinking water andfill it in the machine when the water level is low. This issure not enough to control the water quality in thecompressor system. The water system is not a closedsystem. The air that coming in from the atmosphere bringa lot of bad ions in the system, the water wash all this outand now the ions are in the water system. Further thewater ever take ions from the material inside the system,and try to find balance .

A real water tradement has to messuring and cleanpermanently the water system. Only the from Kirstenpatented system can do this and give the absolute securityunder all conditions that the water quality in the machine isaround the world the same. 30 years of experience with waterlubricated and water injected screw compressors has shownthe way how to do this. When the water in the compressorsystem is regulated between a conductivity from 5 to 10 microsiemens by 20°C, the system runing under safe conditions,water lubricated bearings life time will more then 50.000hours.

This are some short info's about the newdevelopments of water injected and waterlubricated compressors. From the technicalstandpoint this machines should be driven byhigh speed permanent magnet motors. Onlythis type of motor give the optimum inefficiency, noise level etc. about water or oilcooling. I have used more then 15 years thiskind of motors in some of my products.Motors also developed and produced myself.

The Maintenance EngineerThe oil in compressed air aftercompression will attackdownstream equipment,causing increased maintenancerequirements and increasedplant downtime

The Financial ManagerLow cost oil lubricatedcompressors may look attractive,But when considering the totaloperating costs compared to Oilfree compressors, the extrainvestment in a NEW waterinjected screw compressor willeasily pay for itself, special whenpermanent magnet motors areused

The Application EngineerEvery application can benefit fromoil free air compressors with totalproduct safety, lower operating,and maintenance costs and ahealthier working environment

The General ManagerIf you require maximum reliabilityand energy efficiency to improveyour total operating costs, TheZERO EMISSİON SCREWCOMPRESSOR, wıth permanentmagnet motors, provides you withthe optimum compressed airgeneration solution

The Safety and Environment ManagerBreathing oil fumes is definitely not agood idea and oil Condensate candamage the environment So why do itthe hard way, when you can do it thesmart way with oil free compressors

The Quality ManagerDo not accept the possibility ofproduct contamination, and reducedproduct quality. Only 100% Oil freecompressors can offer a 100%Guarantee of Oil Free Air
