A removable U-tube bundle gives this configuration the thermal and mechanical margin expected of SU/WU equipment in steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Dimensionally it is a 6-inch shell unit, 36-inch shell length, and roughly 40-1/8 inches overall in a 4-pass arrangement. That works out to about 12.7 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. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-261-06-036-005. Installations range across radiant panel and snow-melt converters, swimming pool heating, and instantaneous domestic water heating.
