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. Physically, the unit runs a 8-inch shell, 24-inch shell length, and roughly 29-3/8 inches overall in a 6-pass arrangement. That works out to about 12 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. This build is designated 5-261-08-024-003. Typical duty includes radiant panel and snow-melt converters, building comfort heating, and instantaneous domestic water heating.
