this configuration is a SU/WU unit built on a removable U-tube bundle for steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. The configuration measures 16 inches across the shell, 72-inch shell length, and roughly 81-5/8 inches overall in a 2-pass arrangement. That works out to about 227 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. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and N/A maximum temperature. Typical duty includes instantaneous domestic water heating, building comfort heating, and radiant panel and snow-melt converters. This build is designated 5-261-16-072-004.
