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. Physically, the unit runs a 4-inch shell, and roughly 53-1/4 inches overall in a 2-pass arrangement. That works out to about 10.4 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast brass 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. This build is designated 5-271-04-054-002. Typical duty includes process tank heating, hot water storage tanks, and boiler feed and condensate tanks.
