SU104-6

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. The configuration measures 10 inches across the shell, 48-inch shell length, and roughly 53 inches overall in a 6-pass arrangement. That works out to about 45 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as SU104-6. As furnished, materials include cast iron or brass bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in radiant panel and snow-melt converters, building comfort heating, and swimming pool heating.
