SU106-6

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. Dimensionally it is a 10-inch shell unit, 72-inch shell length, and roughly 77 inches overall in a 6-pass arrangement. That works out to about 68 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron or brass bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across radiant panel and snow-melt converters, swimming pool heating, and instantaneous domestic water heating. This build is designated SU106-6.
