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. Dimensionally it is a 10-inch shell unit, 66-inch shell length, and roughly 65-3/8 inches overall in a 2-pass arrangement. That works out to about 78.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include 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 5-276-10-066-002. Typical duty includes hydronic-fed storage systems, hot water storage tanks, and process tank heating.
