The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. The configuration measures 6 inches across the shell, 84-inch shell length, and roughly 88-1/8 inches overall in a 2-pass arrangement. That works out to about 31.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Typical duty includes condensate cooling, hydronic HVAC converters, and pool and storage-tower heating. This build is designated 5-265-06-084-001.
