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. Dimensionally it is a 10-inch shell unit, 48-inch shell length, and roughly 53 inches overall in a 2-pass arrangement. That works out to about 56 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-10-048-004. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Installations range across swimming pool heating, instantaneous domestic water heating, and building comfort heating.
