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. Physically, the unit runs a 10-inch shell, 60-inch shell length, and roughly 59-3/8 inches overall in a 2-pass arrangement. That works out to about 71 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. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are process tank heating, hydronic-fed storage systems, and domestic water storage heating. This build is designated 5-276-10-060-001.
