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. Its envelope centers on a 14-inch diameter shell, 72-inch shell length, and roughly 80-3/4 inches overall in a 4-pass arrangement. That works out to about 167 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-261-14-072-002. Typical duty includes instantaneous domestic water heating, swimming pool heating, and building comfort heating.
