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. Its envelope centers on a 4-inch diameter shell, and roughly 71-1/4 inches overall in a 2-pass arrangement. That works out to about 13.9 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes boiler feed and condensate tanks, wash-down and sanitation water storage, and process tank heating. This build is designated 5-270-04-072-001.
