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 8 inches across the shell, 36-inch shell length, and roughly 41-3/8 inches overall in a 6-pass arrangement. That works out to about 19 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies 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. Installations range across radiant panel and snow-melt converters, building comfort heating, and instantaneous domestic water heating. This build is designated 5-260-08-036-003.
