For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. The configuration measures 10 inches across the shell, 108-inch shell length, and roughly 113 inches overall in a 2-pass arrangement. That works out to about 131 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron 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 375°F maximum temperature. Common applications are instantaneous domestic water heating, radiant panel and snow-melt converters, and swimming pool heating. This build is designated 5-261-10-108-001.
