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 6-inch shell unit, 24-inch shell length, and roughly 28-1/8 inches overall in a 6-pass arrangement. That works out to about 6 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes instantaneous domestic water heating, swimming pool heating, and building comfort heating. This build is designated 5-261-06-024-003.
