this configuration is a TCS/TCW tank heater unit built on a two-pass U-bend bundle for in-tank heating with boiler water in the tubes. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Dimensionally it is a 8-inch shell unit, and roughly 64-1/4 inches overall in a 2-pass arrangement. That works out to about 45 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron 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. Installations range across hot water storage tanks, hydronic-fed storage systems, and process tank heating. This build is designated 5-276-08-066-001.
