The advance of the energy transition, with its focus on power generation from renewable energies, their use and storage, is also creating a growing need for energy storage systems. Normal batteries and rechargeable batteries come into play for e-mobility, in the household, industry and commerce, system infrastructure and for the production of hydrogen. In the temperature treatment of batteries, techniques are required during production that meet the highest safety requirements. For many years, our engineers, technicians and application experts have been using their knowledge and expertise for the benefit of the battery manufacturing industry to realize the best solutions for these customers. We have developed an oven technology for large-scale battery module production that is capable of heating and cooling batteries in a small space and at a high cycle rate, meeting the highest requirements in terms of scalability, reproducibility, accessibility, variability and traceability.
