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 8 inches across the shell, 72-inch shell length, and roughly 77-3/8 inches overall in a 6-pass arrangement. That works out to about 41 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron 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 375°F maximum temperature. This build is designated 5-261-08-072-003. Installations range across swimming pool heating, radiant panel and snow-melt converters, and building comfort heating.
