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 12-inch shell, 48-inch shell length, and roughly 53-1/2 inches overall in a 2-pass arrangement. That works out to about 83 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-12-048-004. The build specifies cast brass 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 N/A maximum temperature. Common applications are instantaneous domestic water heating, swimming pool heating, and radiant panel and snow-melt converters.
