Oil- cooled starters are stepped resistance starters with 3PR3 cast iron resistors in a tank filled with mineral based insulating oil. GINO AG acquired the 3PR3 series from Siemens in the year of 2000. The oil-cooled starters store the heat dissipated during the starting process and slowly release it to the atmosphere via the tank surface.
