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. Physically, the unit runs a 10-inch shell, 48-inch shell length, and roughly 53 inches overall in a 2-pass arrangement. That works out to about 56 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-261-10-048-001. The series sees regular use in instantaneous domestic water heating, radiant panel and snow-melt converters, and building comfort heating.
