For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; 5-261-06-024-004 sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. The configuration measures 6 inches across the shell, 24-inch shell length, and roughly 28 1/8 inches overall in a 2-pass arrangement. That works out to about 8 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Installations range across building comfort heating, radiant panel and snow-melt converters, and instantaneous domestic water heating.
