›› Better cooling, more options and a longer service life

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

Liquid cooling not only enables optimal temperature performance of the component, but also promotes performance and ensures longer component life. The entire body of the component is at an optimum 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 where the supply and exhaust air is low, either because of the design or because of protective measures against environmental influences. This is because the liquid-cooled components have a much smaller size due to fewer cooling fins, while at the same time providing 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, results in consistently high performance and a cooling capacity that can reduce the temperature below ambient.

Another effect of liquid cooling is lower case temperature, so operating personnel are not exposed to burn hazards and waste heat does not interfere with other components. This allows REO products to be used in industrial applications where low surface temperature assemblies are required, such as 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.
