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 8-inch shell, 60-inch shell length, and roughly 65-3/8 inches overall in a 2-pass arrangement. That works out to about 41 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast brass 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 300°F maximum temperature. This build is designated 5-261-08-060-004. Typical duty includes building comfort heating, instantaneous domestic water heating, and swimming pool heating.
