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. Dimensionally it is a 8-inch shell unit, 48-inch shell length, and roughly 53-3/8 inches overall in a 4-pass arrangement. That works out to about 32 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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-261-08-048-005. Common applications are instantaneous domestic water heating, radiant panel and snow-melt converters, and swimming pool heating.
