© 2007 Filter Technik Kausch FTK stands for decades of experience in fluid-filtration in industry and facility management • Dipl. -Ing. Ekhard Kausch works in the fluid filtration industry since 1972: large scale projects as well as modular systems • Since 1999 specialization on fully automatic modular systems specifically for heating/cooling systems • First projects in housing industry in 1986, started as individual projects • More than 20 years of experience in heating water filtration • THE leading brand in serial heating and cooling water micro filtration today! • Patented technology

© 2007 Filter Technik Kausch demand Heating systems with water as energy carrier suffer from mud problems since their introduction. • Main reason is the oxygen contained in the heating water corrosion particle growth sediment build up • damages, wear, and decreased efficiency In the past the consequences were delayed by using large dimensioned boilers, pipes and radiators, energy efficiency was not part of the concept introduction and origin use and demand functions, employment future and discussion

© 2007 Filter Technik Kausch demand Why heating water filtration? • dirt isolates, thus hinders efficient heat transfer • dirt hinders thermostats and control circuitry from proper function • dirt influences the hydraulic balance • dirt wears all mechanical components • dirt pushes heating costs, repair costs and CO 2 -emissions to higher levels • dirt causes severe damage, even total boiler break down Heating water filtration prevents mud pollution and its consequences introduction and origin use and demand functions, employment future and discussion

© 2007 Filter Technik Kausch advantages FTK heating water filters support VDI 2035 and En. EV • According to the German engineering guideline ‘VDI 2035’ the installation of filters or separators is recommended and for some systems mandatory • According to European Energy Saving Bill ‘En. EV’ design of heating plants for maximum energy efficiency in new building projects à FTK heating water filters are a suitable means against mud-sedimentation and the consequences of corrosion on the water side of heating plants introduction and origin use and demand functions, employment future and discussion

© 2007 Filter Technik Kausch advantages The most important advantages: à Heating cost savings due to better heat transfer à Operating cost savings because of repair avoidance à Investment savings due to lifetime extension of the system components à CO 2 - savings due to increased energy efficiency à Savings on chemicals/inhibitors à Supports the VDI guideline 2035 and the ‘En. EV’ à sustainable savings each year - for decades introduction and origin use and demand functions, employment future and discussion

© 2007 Filter Technik Kausch employment mobile filtration in small buildings, flexible use (commercial), … introduction and origin use and demand functions, employment future and discussion

© 2007 Filter Technik Kausch future The market for mobile heating water filtration as a commercial service is undeveloped – in spite of the great demand • Plumbing companies increasingly integrate heating water filtration into their service spectrum • The market is totally open, both commercial customers and house owners profit from clean heating water • Value added for Energy-Contracting und Facility Management companies introduction and origin use and demand functions, employment future and discussion

© 2007 Filter Technik Kausch future In future heating systems will rely on microfiltration. • Advancing and increasingly fine technology in heating requires a steadily clean quality of heating water boiler guarantee only with heating water filter (example Highschool Eutin, Germany) • The hydraulic balance in heating plants with decreasing water amounts and decreasing pipe-diameters becomes increasingly effected by mechanical pollutants • Legal regulations and guidelines like ‘En. EV’ and VDI 2035 proclaim highly efficient heating plants and they will keep intensifying • Continuously increasing prices for fuel and other energy sources as well as maintenance services will make heating water filters become an economical necessity introduction and origin use and demand functions, employment future and discussion
