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. The configuration measures 8 inches across the shell, 36-inch shell length, and roughly 41-3/8 inches overall in a 6-pass arrangement. That works out to about 19 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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes instantaneous domestic water heating, radiant panel and snow-melt converters, and swimming pool heating. This build is designated 5-261-08-036-003.
