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 4 inches across the shell, 48-inch shell length, and roughly 53 inches overall in a 2-pass arrangement. That works out to about 9.19 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers 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. The series sees regular use in radiant panel and snow-melt converters, swimming pool heating, and building comfort heating. This build is designated 5-261-04-048-004.
