5-276-12-096-001

this configuration is a TCS/TCW tank heater unit built on a two-pass U-bend bundle for in-tank heating with boiler water in the tubes. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Physically, the unit runs a 12-inch shell, 96-inch shell length, and roughly 96-1/4 inches overall in a 2-pass arrangement. That works out to about 169 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-276-12-096-001. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
