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 20-inch shell, 36-inch shell length, and roughly 49-3/4 inches overall in a 2-pass arrangement. That works out to about 194 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-20-036-001. The build specifies 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. Installations range across radiant panel and snow-melt converters, instantaneous domestic water heating, and building comfort heating.
