11th International Congress and Exhibition Aluminium Brazing 2021 und ALUMINIUM HEAT EXCHANGER TECHNOLOGIES FOR HVAC&R

Die internationale Branche des Aluminiumlötens und der Wärmeaus-tauschtechnologien trifft sich erstmals online. Der DVS – Deutscher Verband für Schweißen und verwandte Verfahren e. V. und die DVS Media GmbH laden am 4. und 5. Mai 2021 zur digitalen Doppelveranstaltung ein: Der „11th International Congress and Exhibition on Aluminium Brazing“ und der „7th International Congress and Exhibition on Aluminium Heat Exchanger Technologies for HVAC&R“ informieren über aktuelle Trends und den Stand der Technik.

Videopräsentationen von namhaften Branchenvertretern stehen bei der Onlineveranstaltung im Mittelpunkt. Per Chat können sich die Teilnehmerinnen und Teilnehmer austauschen und Kontakte knüpfen. Neben der Konferenz „Aluminium Brazing und HVAC&R“ gibt es auch eine virtuelle Ausstellung, auf der Unternehmen ihre Produkte für das Hartlöten präsentieren können.
