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 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 6 inches across the shell, and roughly 39-1/8 inches overall in a 2-pass arrangement. That works out to about 15 square feet of heat transfer surface on 3/4-inch O.D. tubes. 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. This build is designated 5-271-06-042-001.
