Built around a removable U-tube bundle, this configuration delivers steam-to-liquid heating for demanding service. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 8-inch shell, 60-inch shell length, and roughly 65-3/8 inches overall in a 6-pass arrangement. That works out to about 33 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-08-060-003. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in instantaneous domestic water heating, radiant panel and snow-melt converters, and building comfort heating.
