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

    Solar energy, as a clean energy source, is used all over the world. Solar modules are the heart of photovoltaic systems, which sometimes cover large areas. High light transmission and smooth operation under harsh environmental conditions (rain, dust, high and low temperatures) are mandatory requirements. Highly efficient silicon panels are used to sustainably ensure high efficiency.
    At the same time, solar modules must be produced efficiently. Lightweight construction and sealing concepts are key considerations here. A special bonding process enables fast automated production of modules, but also insulates, conducts heat, seals and relieves cold and thermal expansion stresses. This involves a highly viscous, high-solids and fast-drying single-component adhesive that must meet the high requirements for dynamics and micro-adhesive volume.

      Solution

      The special bearing concept of the high-resolution KEM Helical Flow Meter (SRZ Series), his long-term stability and high reproducibility meet the quality standard for the production process. The application takes place in a closed control loop, in order to achieve an efficient and high-quality gluing process. This requires high resolution, in order to dose very small quantities, precisely and reproducibly. A special degree of hardness of the spindles and a bearing concept developed for highly abrasive adhesives are key for success.
