SU286-4

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. Its envelope centers on a 28-inch diameter shell, 72-inch shell length, and roughly 99-3/8 inches overall in a 4-pass arrangement. That works out to about 703 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as SU286-4. The build specifies steel bonnets, steel shell, copper tubes, and steel 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, building comfort heating, and swimming pool heating.
