Environment & Sustainability

KEM is committed to sustainable environmental protection. We put this into practice by ensuring that every KEM employee uses all resources along the value chain carefully and sparingly – even beyond the require-ments of legal regulations. KEM develops, manufactures, and produces its products with the goal of impacting the environment as little as possible and not endangering people.

In addition, we support the further expansion of green power plants with our flow meters.

Our processes and procedures are subject to regular reviews and continuous improvement.

    Application

    The replacement of conventional combustion vehicles by electric vehicles is revolutionizing the automotive sector significantly. A core requirement for electromobility is the provision of efficient and reliable battery technologies.
    The lithium batteries used in electric vehicles are based on battery stacking technology. In this process several lithium batteries are connected in series to form a power battery (cell). To form a module, the cells are connected in series. Several modules in parallel form a battery pack with high energy density and range. This assembly process not only meets the specifications of the battery, but also requirements for heat dissipation, strength and low weight. To improve the thermal conductivity, a quantity of fillers such as SiO2, Al2O3 with a filler content of 30 - 70 % is added. The adhesive tape must be dimensionally stable and resistant to particle abrasion. The reliable operation at high viscosities and large media particles poses a corresponding challenge to the flow measurement technology. High measuring range dynamics, long-term stability and high reproducibility must be guaranteed.

      Solution

      The high-resolution KEM Helical Flow Meter (SRZ series) is the ideal solution. It meets the quality standard for the production processes through a bearing concept specially adapted to the requirements, long-term stability and high reproducibility.
