The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Dimensionally it is a 8-inch shell unit, 48-inch shell length, and roughly 53-3/8 inches overall in a 2-pass arrangement. That works out to about 32 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. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-261-08-048-001. The series sees regular use in radiant panel and snow-melt converters, building comfort heating, and instantaneous domestic water heating.
