There are often limits to the air cooling of electrical components, especially if the component has to be very compact. In order to continue to guarantee the best possible cooling, a wide range of REO’s inductive and resistive components are equipped with liquid cooling.

Liquid cooling not only allows for optimal temperature behaviour of the component, but also promotes performance and ensures longer component life. The entire body of the component is at an optimal temperature even under full load.

The initially higher investment costs for liquid cooling technology are quickly compensated for by a wide range of advantages. First of all, this technology makes it possible to use the system in confined spaces that have a low air supply and exhaust due to the design or because of protective measures against environmental influences. Because the liquid-cooled components have fewer cooling fins, they are much smaller in size and at the same time have a high cooling capacity. The high efficiency goes hand in hand with a lower noise level, as loud, active fans are not necessary. The advantage increases further the higher the ambient temperature. In this case, a technology based on air cooling would very quickly reach its thermal limits and, contrary to water cooling, lead to a reduction in performance. This is because it is not possible to cool the component below the ambient temperature. The effective dissipation of heat by liquid cooling, on the other hand, leads to a constantly high performance and a cooling capacity that can lower the temperature below the ambient temperature. Another effect of liquid cooling is the lower enclosure temperature, so that operating personnel are not exposed to any risk of burns and the waste heat does not disturb other components. This means that REO products can also be used in industrial applications where assemblies with low surface temperatures are required, such as in the wood and textile industries or in explosion-proof environments. The lower temperature also protects the installed components and extends the service life of the system.
