SU266-6

this configuration is a SU/WU unit built on a removable U-tube bundle for steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Its envelope centers on a 26-inch diameter shell, 72-inch shell length, and roughly 103-15/16 inches overall in a 6-pass arrangement. That works out to about 651 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as SU266-6. Material selection covers 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. Typical duty includes instantaneous domestic water heating, building comfort heating, and radiant panel and snow-melt converters.
