A removable U-tube bundle gives this configuration the thermal and mechanical margin expected of SU/WU equipment in steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 16-inch shell, 48-inch shell length, and roughly 57-5/8 inches overall in a 4-pass arrangement. That works out to about 143 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. 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 5-261-16-048-002. Installations range across swimming pool heating, building comfort heating, and radiant panel and snow-melt converters.
