Dachser SE

For this project, we use the power of opposites in our system concept. The control and automation level of the CCHP system (combined cooling, heat and power) of our customer Dachser Logistics in Memmingen stands out for having maximum flexibility and modularity in the system structure. A geothermal well was integrated, which is both an economical as well as space-saving component. A corresponding combined heat and power plant rounds out the overall concept perfectly.Massive-design containers (together with well pumps)
