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. Dimensionally it is a 6-inch shell unit, 48-inch shell length, and roughly 52-1/8 inches overall in a 4-pass arrangement. That works out to about 17.39 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies 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 swimming pool heating, instantaneous domestic water heating, and building comfort heating. This build is designated 5-261-06-048-005.
