1. Energy, resource, emissions savings for Europeans industry I 1 Optimised exchanger operation and new maintenance equipment will lead to tremendous resource savings AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädlerwww.ac-raedler.at

2. 2  Europeans maintenance market represents a value of 100 Mia. Euro  Of them for Germany 20 Mia. Euro  Heat exchangers are used in large numbers for multiple applications  Nearly no measuring instruments are used for exchanger operation  1 single Austrian service company maintained 500 heat exchanger within half a year 2011  Costs due to over-design, additional fuel consumption and maintenance, loss of production, etc. have been estimated as 0.25% of the GNP of industrialised countries.

3. 3 AC Rädler Environment technique GmbH, www.ac-raedler.at lecture: Sigrun Rädlerwww.ac-raedler.at One don’t need to take a sledgehammer to crack a nut … one don‘t need to use 1000, 3000 bar pressure water to clean heat exchanger – if cleaning operation can success- fully be performed at 12 bar by the RTC equipment. AC Rädler environment technique GmbH, Vienna developed the RTC equipment for most resource saving efficient tubular heat exchanger cleaning. Any kind of hard and even fully blocked tubes are regained by the RTC treatment. In some cases whole exchanger investment is regained. RTC cleaning is recommended for graphite exchangers.
