WELCOME TO THE
1st DIGITAL INTERNATIONAL CONGRESS ON ALUMINIUM BRAZING
AND
ALUMINIUM HEAT EXCHANGER TECHNOLOGIES FOR HVAC&R
IN COMBINATION WITH A DIGITAL EXHIBITION

Last year we decided to postpone the Congress on Aluminium Brazing (due
to COVID-19) to 2021 and to link this event with the congress on Aluminium
Heat Exchanger Technologies for HAVC&R. A combination of both events
will enable more attraction to a wider audience of the aluminium brazing
community.

We are still sticking to this concept, but we are forced to hold the event
digitally. We will combine pre-recorded video presentations with an exciting
innovative and interactive conference format. Using an additional chat func-
tion you can also exchange ideas with other attendees.

We also offer a virtual platform for the exhibition! Exhibitors can present
their products.

This event will remain an excellent opportunity for all attendees meeting
online with leading specialists, authorities and well-known experts.

The congress is truly an event which anyone involved in sophisticated joining
challenges should attend, even if it will solely take place online.

We look forward to meeting you in the virtual Aluminium Brazing world!

                                                                           3
