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. The configuration measures 12 inches across the shell, 84-inch shell length, and roughly 89-1/2 inches overall in a 4-pass arrangement. That works out to about 139 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-12-084-005. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in instantaneous domestic water heating, swimming pool heating, and building comfort heating.
