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 20-inch shell, 72-inch shell length, and roughly 85-3/4 inches overall in a 2-pass arrangement. That works out to about 388 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-20-072-001. As furnished, materials include 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. Common applications are instantaneous domestic water heating, swimming pool heating, and radiant panel and snow-melt converters.
