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 10 inches across the shell, 120-inch shell length, and roughly 125 inches overall in a 2-pass arrangement. That works out to about 146 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include 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. Installations range across building comfort heating, instantaneous domestic water heating, and radiant panel and snow-melt converters. This build is designated 5-261-10-120-004.
