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 18-inch shell, 84-inch shell length, and roughly 96-1/2 inches overall in a 2-pass arrangement. That works out to about 339 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-18-084-001. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes instantaneous domestic water heating, swimming pool heating, and building comfort heating.
