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. Physically, the unit runs a 4-inch shell, 36-inch shell length, and roughly 41 inches overall in a 2-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-04-036-001. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are building comfort heating, instantaneous domestic water heating, and radiant panel and snow-melt converters.
