5-265-10-084-001

The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and 5-265-10-084-001 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 10-inch shell, 84-inch shell length, and roughly 89 inches overall in a 2-pass arrangement. That works out to about 101 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Typical duty includes hydronic HVAC converters, pool and storage-tower heating, and condensate cooling.
