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. Physically, the unit runs a 8-inch shell, and roughly 34-1/4 inches overall in a 2-pass arrangement. That works out to about 23 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-276-08-036-002. Typical duty includes hydronic-fed storage systems, domestic water storage heating, and process tank heating.
