Dachser tests emission-free reefers

Four battery-electric refrigerated truck trailers from Krone have been put to the test in the DACHSER network as part of the German logistic company’s Climate Protection strategy.

The eTrailers will be used in Erlensee, Hamburg and Langenau as DACHSER aims to gain experience, with the still evolving technology, in everyday logistics.

“We now have the opportunity to put the technology through its paces in everyday operations,” said Department Head of Production and Network Processes at DACHSER Food Logistics, Tobias Ritter. “When transporting food, the cold chain must never be interrupted. Therefore, the refrigeration must always function reliably, the ranges must be stable and longer downtimes must also be possible.”

With a fully charged battery, the trailer can be cooled for around five to six hours, even without an additional external power supply or the generator axis. The battery is charged within three to four hours directly at the loading gates. This is also where the pre-cooling takes place.

In addition to the battery, the generator axis supplies energy for cooling using kinetic energy from driving. If the truck is traveling at more than 20 km/h, the generator axis supplies enough power to operate the cooling system completely independent of the battery and also to charge the battery.

The use of battery-electric refrigerated truck trailers not only improves the carbon footprint of food transportation, they also cause significantly less noise than diesel refrigeration units.

Various test scenarios are now being played out at the three branches, starting with the use of the eTrailer in the shuttle service and on local journeys, up to long-distance routes.

“Together with our long-standing trailer partners, Krone, Krone-Fleet and Carrier Transicold, we are deliberately taking the step of testing new technologies in live operation,” said Department Head Technics/Technical Purchase at DACHSER, Christian Schütz. “In the future, we want to deploy even more of these units to support our climate protection goals.”
