Not only since the new geopolitical situations in 2022 has the electrification of products or entire industries been in high demand. The electrification of mobility is progressing in all sectors of the economy, and REO components prove their resilience and reliability every day. Thanks to the high scalability of the power classes, mobility solutions can be electrified, from small autonomous robots to buses and container ships. The advantages of electrified drives are obvious. Compared to conventional drive types such as the internal combustion engine, electric drives have a very good degree of efficiency. At the same time, the e-drives have a significantly lower weight in relation to their power and cause no local emissions. However, in order for an electrified drive system to work safely and reliably, special components are required. For example, REO braking resistors protect the machine from overvoltage in the DC link. For your applications (e.g. wind power technology, railway technology, automotive technology) they guarantee a high level of operational safety and are overload-proof in the event of short-term loads. The charging resistor, on the other hand, is a current limiting resistor for charging and discharging capacitors and limits, for example, the inrush current flowing into the DC link capacitor. For this purpose, the device must be designed for a high single pulse energy and rated voltage. For particularly effective cooling in the most adverse conditions, REO offers a wide range of liquid-cooled components. Liquid-cooled resistors, such as the REOHM D 330 from REO, are significantly smaller than conventional air-cooled resistors and are available in power ratings up to 60 kW. The efficient cooling is achieved by means of cooling channels incorporated in the heat sink, which enable cooling below the ambient temperature and create a safety-relevant spatial separation of the current-carrying and liquid-carrying lines. Further advantages are a high power density and an efficient and low-noise operation.

REO products are characterized by a long service life and low maintenance requirements. This not only has financial advantages, but also saves resources that are needed for new products or spare parts. With our products, you can therefore contribute to minimizing the global waste of resources. Become part of REO’s consistent path to greater sustainability. We have set the course for a sustainable future and stand behind our ambitious goals. Our claim is based on the holistic strategy of reducing emissions and consumption in all production and company areas.
