Heat Exchanger Fouling & Cleaning Conference XIV

Postponed until 2022

With the continued uncertainty involving the global pandemic, we have consulted with the Technical Committee and made the difficult decision to postpone the Heat Exchanger Fouling & Cleaning Conference until June 2022.

Although we will miss seeing you next year in Austria, our priority is the health and safety of attendees and staff, and we believe that postponing the conference is the best solution to ensure this. We also wish to maintain the continued success by keeping with its current in-person format, which encourages discussion and interaction.

For those of you who submitted an abstract, we thank you and, unless you notify us otherwise, will hold them for consideration at our re-scheduled event.

We remain excited to host you and will provide more information on specific dates as soon as possible. For now, we appreciate your understanding and wish you all the best. We look forward to seeing you in June 2022!
