Built around a removable U-tube bundle, this configuration delivers steam-to-liquid heating for demanding service. Steam condenses in the single-pass shell while the heated fluid travels the tubes. The configuration measures 4 inches across the shell, 72-inch shell length, and roughly 77 inches overall in a 4-pass arrangement. That works out to about 13.9 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-260-04-072-012. The series sees regular use in swimming pool heating, instantaneous domestic water heating, and radiant panel and snow-melt converters.
