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. Its envelope centers on a 4-inch diameter shell, 84-inch shell length, and roughly 89 inches overall in a 2-pass arrangement. That works out to about 16.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are building comfort heating, swimming pool heating, and instantaneous domestic water heating. This build is designated 5-261-04-084-004.
