5-271-12-048-002

5-271-12-048-002 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. Its envelope centers on a 12-inch diameter shell, 48-inch shell length, and roughly 48-1/4 inches overall in a 2-pass arrangement. That works out to about 83 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. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes process tank heating, boiler feed and condensate tanks, and wash-down and sanitation water storage.
