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 8-inch shell unit, 72-inch shell length, and roughly 77-3/8 inches overall in a 4-pass arrangement. That works out to about 49 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-08-072-002. Material selection covers cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are radiant panel and snow-melt converters, swimming pool heating, and instantaneous domestic water heating.
