At the only inland waterway transportation fair in Germany from the 24th of September to the 25th of September in Kalkar, aentron GmbH took part for the first time. Most of the exhibitors were shipyards or ship mechanics, but you could also find some of the most important engine manufacturers. At our joint stand with Kräutler Elektromaschinen GmbH and three other exhibitors, we exchanged the most important news of the maritime business and had some really interesting talks with the attendance as well as with our co-exhibitors. In particular we presented our 10 kWh module for the commercial navigation which is officially certified by the DNV-GL. This gained a really high interest by the visitors as well as by the co-exhibitors.
