A two-pass U-bend bundle gives 5-271-04-036-002 the thermal and mechanical margin expected of TCS/TCW tank heater equipment in 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. The configuration measures 4 inches across the shell, and roughly 35-1/4 inches overall in a 2-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
