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, 48-inch shell length, and roughly 53 inches overall in a 2-pass arrangement. That works out to about 9.19 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-260-04-048-011. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in swimming pool heating, building comfort heating, and instantaneous domestic water heating.
