The Unconventional Hydrojetting Technology Center (CNTH) was formed in 1.06.2006 on The Koszalin University of Technology as the separated posefaculty science unit. Content-related experience of The Center consists of the almost twenty year achievements put into practice by following research institution: HAT BORTEX Ltd - Koszalin, Innovative-implementing Plant in Koszalin, ProEcological Technologies Center in Koszalin as well as Machine Construction Basis Department and Mechanical Engineering Department. At present Center is the only institution which deals with basic and development researches heading for complex utilization of high pressure water jet as a versatile erosion tool. Despite short time of existence CNTH is the member of elite consortium RIMAMI, formed by 14 the most important science institutions and 6 great economic institutions achieving status of Advanced Technologies Center.
        Integration of economy and science environment through creating science-research grids and supporting interdyscyplinary activities in aid of hydrojetting technology development determines the principal aim of The Unconventional HydroJetting Center which helps to create content-related and innovative back-up facilities in range of high-pressure water jet utilization. The CNTH's operations are adjust for international activities however in the first place we offer our competences to polish institutions, companies and organizations.
        The real beginning of activities in field of hydrojetting technology in Koszalin dates back to 1987 when prof. Jozef Borkowski formed one of the first in Poland half private research-science institution: BORTEX Hydroabrasive Comp. Ltd.. This company was equipped with set of high-pressure technological devices which made up the full cutting system - Streamline Hydroabrasive - produced by American Company Ingersoll-Rand. The main aim of statutory activity of BORTEX was promotion of technological progress in field of hydrojetting processing but especially popularization of high-pressure abrasive water jet cutting technology. American programs based on high-pressure water jet utilization were put into practice in this institution, as well as building of original system BorJet developed on basis of abrasive suspension jet cutting concept using lowered pressure in comparison with produced then high-pressure systems. Development of prototype construction of this new system (BorJet 01) with its technological research was continued within the confines of Central Program of Basic Research. (C.P.B.P. 02.04). This device was successfully applied in professional cutting of multilayer glass in trade companies as well as made possible scientific researches in this field in then the Higher School of Engineering.
        To adjust to dynamic transforming economy situation BORTEX got split to another specialized companies which kept realizing proinnovative research programs. Such implement example may be regeneration and hydrojetting cleaning of pipeline installation, abrasive hydrojetting machining of hulls and also adjusting hydrojetting technology to loosening and repairing of constructions especially airstrip as well as municipal and industrial waste utilization, minerals deaeration, explosives washing out from great bore ammunition or assistance of conventional hardprocessing materials machining processes. In years 1993-1994 nine specialized in this field companies formed Proecological Technology Center, in which was afterwards rearranged into three units specializing in extensive surfaces machining, pipeline and hydrotechnical installations cleaning.
        Some of the unique technologies applied in BORTEX and Proecological Technology Center were also transfered to then Higher Engineering School where in May 1988 was formed Unconventional Technology and Equipment Institution which in 1991 was converted into Machine Construction Basis Department. Then in 1996 this Department was reorganized and divided into three new R&D units including present Mechanical Engineering Department. Finally, in order to intensify R&D study over unconventional hydrojetting technologies there was formed (1.06.2005) The Unconventional HydroJetting Center (CNTH) of Technical University of Koszalin.
        Dominant subject area of research activities of this Center was hydrojetting erosion caused by high-energetic water jet,with mono- and multiphase stucture, showing especially among other things in theoretical study of erosion basis which was caused by high-pressure abrasive-waterjet assisted by cavitation development and cryogenic application controll. Knowing mechanisms deciding about high-pressure water jet erosion helped in working out effective method of forming abrasive slurry jet and taking up study over high-pressure abrasive-water stream with lower pressure application, including microprocessing realized according to analogical MicroBorJet system, as well as processing with originally worked out various kinds of high-pressure ice-water and hybrid jet: abrasive-water-ice jet (CO₂).
        The Unconventional HydroJetting Technology Center is presently unique in the world and the only one in Poland research institution dealing with basic and research studies, aiming to complex utilization of high-pressure waterjet as versatile erosion tool. Principal objective of this Center is transfer of the newest world's technologies utilizing high-pressure waterjet energy and leading studies over hydrojetting technologies and integration of science sphere and economy through innovative creating in aid of hydrojetting technology development and their practical applications. The Center's activities are adjust on international activity but in first place we offer our service to the polish institutions and organizations, especially small and medium companies. In this field we keep up current contacts with approximately 400 intitutions where 50 of them signed agreement with us. In such field of activities we use our own solutions and practical (107 own projects applied in practice) as well as experience acquired during cooperation with friendly science institutions in USA, Brasil and Japan.
        R&D output in field of high-pressure waterjet basic studies and applications created by Center's staff especially by direction, reaches 200 publications (1 qualifying as assistant professor thesis, 10 doctor's thesis, 5 books, 186 science articles). Additionally 107 projects were applied in practice as original (5 patents) high-pressure waterjet applications, mainly to hard to reach pipeline contaminations removal and surface processing. International specialists have very high opinion of this output. Detailed examples of individual Center's direction R&D output is available in mentioned below personal characteristics.
        Center's President prof. dr hab. inz. Przemyslaw Borkowski, who obtained his all grades with honorable, mainly deals with R&D studies over high-pressure waterjet. In this field he issued 2 books and 74 articles (half were in English) and participated in implementing 47 development works and worked out 2 patents. He actively took part in more than 20 science conferences, including 9 the most important international conferences, where one them (Water Jetting 2006) is organizing with his help in Gdansk. Moreover he took part in 15 short-term seniorities and international visits in renowned science centers and delivered lectures on American and Korean universities. President is a member of following science associations: Water Jet Technology Association (USA); The Water Jet Technology Society of Japan; Arbeitskreis Wasserstrahltechnologie, Germany; International Society of Water Jet Technology; Polish Water Jet Group; Polskie Towarzystwo Energetyki Slonecznej IPPT PAN.

        Center's vice-president prof. dr hab. inz. Jozef Borkowski in mentioned above field issued about 100 works; however all in he issued over 200 publications and 11 books (including 2 foreign) and over 100 variable critical reviews, opinions and expertises as well as 70 original reports and R&D work outs from where about 50 was implemented and 3 were patented. He actively participated in over 60 conferences and cooperated with about 40 foreign science stations. Repeatedly he worked at USA Universities. He was the youngest Rector in Poland in two terms 1981-1987, but earlier he was the President of Production Technology Institution and Machine Construction Institute as well as variable lesser science stations. The member of foreign research societies: The Japan Society of Precision Engineering; U.S. Water Jet Technology Association; Arbeitskreis Wasserstrahltechnologie; The International Fluidics Service Company and others. Many times rewarded including individual PAN reward (1979), 10 MEN rewards (prior MNSzWiT), 4 NOT rewards and many national distinctions (Krzyz Kawalerski i Krzyz Oficerski Orderu Odrodzenia Polski) as well as foreign distinctions (American medal Education-Research-Service).
        Currently The Unconventional HydroJetting Technology Center owns several complete pump units and high-pressure hydromonitors with solid technological fittings, mostly made in Germany, Japan and America. Those devices were built to realize determinate technological processes including original BorJet and MicroBorJet systems used to slurry jet cutting and many others connected with it research stations. Center possesses also specialist investigative and measuring apparatus as well as apparatus used to evaluation of processed surfaces such as complex three-dimensional surface analyzer Talysurf CLI 2000, Taylor-Hobson.

        For statutory objectives NTH Center bought, currently expansioned, monumental building with 1000 m² usable area. Recently NTH Center obtained UE grant for 1 million EUR for laboratories development, but mainly for completing necessary apparatus. Within the confines of this grant we are going to buy precise machine tools to hydrojetting cutting, high-pressure hydro monitor with large water expense equipped with numerous heavy duty units as well as measuring apparatus such as scanning microscope equipped with chemical spectrometer EDS and self-propelled camera to hard to reach pipelines monitoring.
