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. Physically, the unit runs a 12-inch shell, 60-inch shell length, and roughly 66-1/2 inches overall in a 4-pass arrangement. That works out to about 98 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast brass bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Installations range across building comfort heating, swimming pool heating, and instantaneous domestic water heating. This build is designated 5-261-12-060-005.
