Heat Exchanger Fouling & Cleaning Conference Series


The fouling of heat exchangers in processing industries remains an ongoing challenge. Costs due to over-design, additional fuel consumption and maintenance, loss of production, etc. have been estimated as roughly 0.25% of the gross domestic product (GDP) for industrialized countries. In addition to the appropriate selection of operating conditions and exchanger geometry, there are numerous chemical and mechanical methods to mitigate fouling and to remove deposits from the heat transfer surfaces. However, all methods to reduce fouling require some understanding of the mechanisms of the deposition process and of the structure and adhesion of deposits on the heat transfer surfaces.

The aim of this biennial conference is to facilitate innovative thinking and to explore new theoretical and practical approaches to address the tremendous challenges associated with the fouling of heat exchangers. It also provides an opportunity for experts from industry, academia and research centers from around the world to present their latest research and technological developments in fouling mitigation and cleaning strategies. In addition to academic research, industrial case studies are welcomed.

Dr.-Ing. Hans U. Zettler

Conference Chair
Heat Transfer Research, Inc. USA

Hans U. Zettler is the President of HTRI. He has a PhD in Chemical Engineering from the University of Surrey, Guildford, UK, and a mechanical engineering degree (Dipl.-Ing.) from the Technical University Karlsruhe, Germany. Zettler is a member of the German Engineering Society (VDI), a member of the VDI-GVC Working Party on Heat and Mass Transfer, an associate member of the Institution of Chemical Engineers (IChemE), and a committee member of the Heat Transfer Society, United Kingdom.

Building on the resounding success of previous gatherings in San Luis Obispo (1995), Lucca (1997), Banff (1999), Davos (2001), Santa Fé (2003), Irsee (2005), and Tomar (2007), the 8th conference in this esteemed series convened in Schladming, Austria (2009). Orchestrated by a dedicated team, the 2009 conference diverged from the customary organization by Engineering Conferences International (ECI) and instead became an integral part of the EUROTHERM Seminar Series. Subsequent conferences transpired in Crete (2011), Budapest (2013), Enfield (2015), Madrid (2017), and Warsaw (2019). The 14th Heat Exchanger Fouling & Cleaning Conference was held in Wagrain, Austria, and marked the seminal reunion of esteemed experts following the unprecedented global pandemic.

The conference is held over multiple days. Morning and afternoon/evening sessions are scheduled to provide a stimulating balance between formal presentations, small group interactions, and informal discussions. The conference attracts representatives from a wide range of universities, research institutes, and companies, thus providing participants with excellent technical presentations and a very conducive environment for discussions. The number of participants is limited to avoid parallel sessions and to foster personal contacts.

This website intends to keep you informed about the past and future conferences of this series. In addition, it provides you with free access to all the reviewed publications of from past conferences.
