A two-pass U-bend bundle gives this configuration the thermal and mechanical margin expected of TCS/TCW tank heater equipment in 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. Its envelope centers on a 12-inch diameter shell, 78-inch shell length, and roughly 78-1/4 inches overall in a 2-pass arrangement. That works out to about 137 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-276-12-078-001. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
