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 12-inch shell, 36-inch shell length, and roughly 41-1/2 inches overall in a 4-pass arrangement. That works out to about 58 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-12-036-005. As furnished, materials include cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Typical duty includes building comfort heating, instantaneous domestic water heating, and swimming pool heating.
