this configuration is a TCS/TCW tank heater unit built on a two-pass U-bend bundle for in-tank heating with steam in the tubes. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Dimensionally it is a 12-inch shell unit, 42-inch shell length, and roughly 42-1/4 inches overall in a 2-pass arrangement. That works out to about 72 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-271-12-042-001. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
