5-261-10-036-001

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 10-inch shell unit, 36-inch shell length, and roughly 41 inches overall in a 2-pass arrangement. That works out to about 42 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-10-036-001. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Typical duty includes radiant panel and snow-melt converters, building comfort heating, and instantaneous domestic water heating.
