Built around a two-pass U-bend bundle, this configuration delivers in-tank heating with steam in the tubes for demanding service. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Its envelope centers on a 8-inch diameter shell, and roughly 22-1/4 inches overall in a 2-pass arrangement. That works out to about 15 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-271-08-024-001. 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. Installations range across process tank heating, boiler feed and condensate tanks, and hot water storage tanks.
