For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 8-inch shell, 84-inch shell length, and roughly 89-3/8 inches overall in a 4-pass arrangement. That works out to about 58 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include 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 5-261-08-084-002. Installations range across building comfort heating, instantaneous domestic water heating, and radiant panel and snow-melt converters.
