“ ‘Won’t work’, does not figure in my vocabulary”

Peter Förnsel, co-inventor of Openair® plasma technology, is marking his 67th birthday by stepping down from his management role at Plasmatreat and becoming a consultant.

(bri) Steinhagen. Gyro Gearloose lives in Westphalia under the name of Peter Förnsel. He was not born in Duckburg, but rather in Berlin-Spandau in 1940 as the son of a mechanical engineer. Today he has a white beard, is over six feet tall and his sign of the zodiac is Virgo – which for many might explain his attachment to technical perfection and critical analysis, his attention to detail and also his unassuming and retiring nature.

The inventor is happiest to be hidden away from all his colleagues in his research den, fiddling and puzzling over things until once again another of his inventions is ready for a patent application to be filed. These always involve energy: electrons and ions, electronic circuits, high voltage and generators, but above all plasma, the fourth state of matter, so called because it follows the solid, liquid and gaseous states. The name “Gyro Gearloose” would indeed be fitting because Peter Förnsel, the 67-year old managing partner of Plasmatreat GmbH, Steinhagen, has actually invented special jets and in doing so marked up another triumph. These jets are used for deploying the Openair® plasma technology that he along with his business partner Christian Buske developed about 10 years ago. This technology is a ground-breaking technique in industry for the environmentally friendly and highly effective pretreatment of the surfaces of materials.

The inventive spirit in Peter Förnsel became apparent quite early. “It started when I was eight.” recalls the imposingly built manager with an amused smile, “I pinched my father’s new alarm clock and dismantled it into its component parts. I then assembled some of the parts in a new and slightly different way and suddenly I had a little vehicle that started moving.” From that moment on no technology was entirely safe from him, but quite a few years were to pass before Förnsel invented the plasma jets that are now known throughout the world.

In the year of his birth events were dominated by the Second World War. His father found a salaried position in Sudetenland, but in 1945 the family had to flee from the Russians to the grandparents in Bielefeld. From there they moved first of all to Bavaria, later to Krefeld and finally back to Westphalia. After completing his school-leaving examinations Peter Förnsel went on to train as an electric power engineer, a subject area that has long fascinated him. For many years he worked in a company as a developer of generators for the pretreatment of materials by the corona process.

After he successfully constructed a corona installation to his own design for use in the printing sector he resolved at the age of 54 to make himself independent and founded his own company. Just a year later, in 1995, he met up with Christian Buske, who recognising the potential became a partner. Christian Buske has an exciting vision: pretreatment should be possible not only by the corona process but also by a substantially more effective and more economically efficient jet process. Such a jet, however, and the plasma beam needed to feed it, first had to be invented. To be properly effective a plasma beam needs to be adapted very specifically to the surface to be treated. Förnsel quickly grasps the problem, “For this purpose we need air, a directed stream of compressed air that steers the plasma and transports the beam through the jet head with pinpoint accuracy onto the surface to be treated.” What no-one guesses at the time is that this solution is the start of a plasma technology that would soon take on a global life of its own under the name of Openair®. 

Only two years later an envisaged rotary system follows which is immediately taken up by industry. Renowned research institutes, with the Fraunhofer IFAM leading the field, begin to take interest in the innovative plasma technology and close collaboration starts. Shortly after, in 1999, the joint company is given the name “Plasmatreat”. 

Patent applications are filed internationally for Förnsel’s and Buske’s developments. Also in 1999 collaboration with the American market starts and a little later with Asia. Development proceeds apace: in 2003 Förnsel discovers the solution to coating and uncoating materials with Openair® plasma, a process that is setting standards for protecting metals against corrosion in the automotive industry. In these few years Buske drives international expansion onwards and by 2007 Plasmatreat is global leader in the supply of atmospheric-pressure plasma systems with technology centres in Germany, North America and Japan as well as establishments and agencies in 18 countries.

“The development of the company fills me with enormous pride” declares Peter Förnsel and in reply to the question whether it is now all over with the inventive activity he replies with a smile: “ ‘Won’t work’, does not figure in my vocabulary. There are many important inventions to the benefit of Plasmatreat still running around in my head. As a close advisor in future I will bring them into the company.”
