5-261-20-048-001

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 20 inches across the shell, 48-inch shell length, and roughly 61-3/4 inches overall in a 2-pass arrangement. That works out to about 259 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-20-048-001. Material selection covers cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across swimming pool heating, radiant panel and snow-melt converters, and instantaneous domestic water heating.
