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.
Type ONW: Oil Natural Water
Oil Natural Water - shell & tube heat exchanger with natural oil convection on the shell side & water through the tube
Type OFW: Oil Forced Water
Oil Forced Water - shell & tube water cooled transformer oil cooler
