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. Dimensionally it is a 6-inch shell unit, 72-inch shell length, and roughly 76-1/8 inches overall in a 4-pass arrangement. That works out to about 26.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers 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. This build is designated 5-261-06-072-002. Installations range across instantaneous domestic water heating, radiant panel and snow-melt converters, and building comfort heating.
