Water Cooled Transformer Oil Coolers
Type ONW or OFW?
Industry advances continue to drive the need for larger capacity coolers. Wabtec has developed two shell & tube external, large capacity water operated cooler systems – Type ONW (natural convection oil flow) and Type OFW (forced oil & water flow). Both types feature our unique, double concentric Leak Detector Tubes design to eliminate the risk of tube leaks.
