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 8 inches across the shell, 48-inch shell length, and roughly 53-3/8 inches overall in a 4-pass arrangement. That works out to about 32 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies 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 swimming pool heating, instantaneous domestic water heating, and radiant panel and snow-melt converters. This build is designated 5-261-08-048-002.
