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 8-inch shell, and roughly 16-1/4 inches overall in a 2-pass arrangement. That works out to about 11 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in boiler feed and condensate tanks, hot water storage tanks, and process tank heating. This build is designated 5-270-08-018-001.
