The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. The configuration measures 10 inches across the shell, 84-inch shell length, and roughly 89 inches overall in a 2-pass arrangement. That works out to about 101 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-10-084-001. The build specifies 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. Installations range across instantaneous domestic water heating, radiant panel and snow-melt converters, and swimming pool heating.
