The TCS/TCW tank heater platform pairs a two-pass U-bend bundle with proven shell-side baffling, and this configuration applies that design to 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. Physically, the unit runs a 4-inch shell, and roughly 17-1/4 inches overall in a 2-pass arrangement. That works out to about 3.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-271-04-018-001. 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.
