SYSTEM CONNECT Tired of having to design your piping and tower layout to i�_� accommodate the standards of cooling tower manufactur- �� c' ._ ers? Marley's SystemConnect'" variety of piping systems — ` ®1 accommodates your design intentions to make your layout / of the NC Series both expedient and economical ® _____.. o Single or dual hot water inlet connections. o Side inlet, bottom inlet or top inlet connections. o Side or bottom cold water outlet connections. o A variety of makeup, overflow and drain options. All piping from the single inlet connection to the distribu- tower package. Installation and tion basins is part of the p 9 � I design costs are reduced and the need for extra piping and supports are eliminated. The single bottom inlet connection is perfect for multicell applications— keeping all the inlet I 1 `. _ piping below the tower. Unless otherwise specified, single -cell towers normally have a side - outlet suction appropriate for the design water flow rate —see pages 16 and 17. This usually assures the lowest possible installed tower elevation. Side - suction con- nection pipes extend roughly 3" outside the basin, and are beveled for weld connection and also grooved for a me- chanical coupling. Multicell towers, intended to operate together as a common unit, are joined by steel flumes between the Outlet piping can be kept below the cold water basin collection basins. These flumes equalize the operating level by choosing either a depressed sump or a bottom water level between basins and also provide a flow pas - outlet connection in lieu of the side suction. Both outlet sage from cells not equipped with outlets or makeup valves, designs conform to standard class 125 ANSI pipe flange often eliminating the need to specify an outlet and makeup specifications. Easily removable debris screens are op- valve for each cell on a multicell installation. Select the tional on bottom outlets and are standard on all other outlet number of outlets required to maintain a maximum flow of arrangements. 1,371 GPM through -each flume for NC1 through NC6 and Depressed sumps are made of inert FRP or heavy- NCA models and 2,203JGPM for NC7 through NC9 and gauge welded stainless steel. Unless otherwise specified NCB through NC odels. Flow values are for side - towers with galvanized steel collection basins are supplied suctions or bottom - outlets without trash screen.
