SU62-2

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 6-inch diameter shell, 24-inch shell length, and roughly 28 1/8 inches overall in a 2-pass arrangement. That works out to about 8 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as SU62-2. The build specifies cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across swimming pool heating, instantaneous domestic water heating, and building comfort heating.
