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 18 inches across the shell, 60-inch shell length, and roughly 72-1/2 inches overall in a 4-pass arrangement. That works out to about 242 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. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-260-18-060-002. Typical duty includes building comfort heating, instantaneous domestic water heating, and radiant panel and snow-melt converters.
