The AuRü LW was developed on the basis of draft legislation from the German government and the European Union and already fulfills the future requirements that legislators will place on operators. You can find out exactly what these are in the section

section. It is a hybrid of AuRü W and AuRü L. The system works with a separator system that separates the oil from the water in accordance with the law and with electronic components consisting of a pressure sensor, water level sensor, glycol sensor, control box and connected fast-closing valves that are responsible for glycol protection. For open systems or circuits with a pressure equalization function, the AuRü LW should definitely be used, as it also has a glycol sensor which, in addition to pressure monitoring, can also detect small leaks (drip and splash water losses). The valves are closed when de-energized so that the tray system is closed even in the event of a power failure.
