The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and 5-260-04-060-012 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 4 inches across the shell, 60-inch shell length, and roughly 65 inches overall in a 4-pass arrangement. That works out to about 11.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are radiant panel and snow-melt converters, swimming pool heating, and instantaneous domestic water heating.
