Built around a two-pass U-bend bundle, this configuration delivers in-tank heating with boiler water in the tubes for demanding service. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. The configuration measures 4 inches across the shell, and roughly 95-1/4 inches overall in a 2-pass arrangement. That works out to about 18.6 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. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across hot water storage tanks, process tank heating, and domestic water storage heating. This build is designated 5-276-04-096-001.
