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. Physically, the unit runs a 12-inch shell, 96-inch shell length, and roughly 104-1/2 inches overall in a 6-pass arrangement. That works out to about 139 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. Common applications are hydronic HVAC converters, pool and storage-tower heating, and condensate cooling. This build is designated 5-266-12-096-003.
