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. Dimensionally it is a 8-inch shell unit, and roughly 28-1/4 inches overall in a 2-pass arrangement. That works out to about 19 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. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in hot water storage tanks, process tank heating, and boiler feed and condensate tanks. This build is designated 5-271-08-030-001.
