This 1080 sq. ft. condenser with auxiliaries is the smallest, most compact, lightweight assembly of condensing equipment ever built. A double-banked two-stage air ejector is mounted on top, the oil cooler on the side, and a propeller-type circulating pump is built into the water box on the end. The steel plate shown in front, one of the flexible supports, eliminates the necessity of an ex- pansion joint. _ Engineering that Cuts Shipbuilding Costs... AVINGS in ship construction are of vital interest to the owner and operator, because carrying charges of such major importance as depreciation, insurance and interest are reduced accordingly. Maintaining their progressive record in marine engineering, Westinghouse engineers have again contributed toward making ships less costly to build, operate and maintain. The accompanying illustration shows a new and unique arrangement of condenser, air ejector, circulating pump, and oil cooler, which is a distinct advance in the build- ing of better ships at less cost. This com- bined unit is installed in the first geared- turbine tugboat in the world now in opera- tion on the Great Lakes. The unit elimi- nates not only the foundation for itself, but also for each of its three auxiliaries. Construction cost is still further lowered because of the minimum amount of piping required and the absence of an expansion joint. Maintenance will be low because every part is 100 per cent accessible. There are fewer pipe joints and but one rotating element. Operation will be cheaper because this apparatus, both in design and arrangement, is inherently more efficient than any other equipment for the same purpose.
