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. Physically, the unit runs a 4-inch shell, 24-inch shell length, and roughly 29 inches overall in a 2-pass arrangement. That works out to about 4.5 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. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are swimming pool heating, building comfort heating, and radiant panel and snow-melt converters. This build is designated 5-261-04-024-004.
