Configured for steam-to-liquid heating, this configuration carries the removable U-tube bundle construction that defines the SU/WU range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 6-inch shell, 84-inch shell length, and roughly 88-1/8 inches overall in a 2-pass arrangement. That works out to about 31.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-06-084-004. Standard construction uses 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 swimming pool heating, building comfort heating, and instantaneous domestic water heating.
