5-261-10-084-002

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 10-inch diameter shell, 84-inch shell length, and roughly 89 inches overall in a 4-pass arrangement. That works out to about 96 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. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-261-10-084-002. Common applications are building comfort heating, instantaneous domestic water heating, and swimming pool heating.
