The 500 KW radiator assembly may be mountedseparately from the generator set. The horizontal andvertical displacement of the radiator from the engine'scenterline will determine the additional systemcomponents necessary for the installation. Sinceparticular installation requirements will vary, it isadvisable to contact the Cognizant Authority regardingremote radiator system requirements. Figures 17-10through 17-12 illustrate deaerating and auxiliary tankpiping. Figure 17-13 illustrates a simple remote radiatorinstallation, with an electric motor driven fan used as aheat exchanger for engine coolant. The radiator ismounted so that the radiator top tank is the highest pointin the water system, preventing air pockets which couldcause stoppage of coolant flow and consequent engineoverheating. The top tanks of the radiators used on the500 KW generator set are of oversized design and in theapplication shown act as a surge tank. A filler neck andpressure cap are supplied to allow for coolant filling andpressurized system operation. Air can be-vented fromthe system by means of a float-type trap which allowsthe escape of air, but not allow water to escape. The airescape trap should have a pipe extending down into the17-16
