SU207-6

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 20-inch diameter shell, 84-inch shell length, and roughly 97-3/4 inches overall in a 6-pass arrangement. That works out to about 413 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron or brass bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are N/A on the shell side, N/A on the tube side, and N/A maximum temperature. This build is designated SU207-6. Common applications are instantaneous domestic water heating, swimming pool heating, and building comfort heating.
