The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and 5-266-10-084-004 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. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in condensate cooling, oil cooling and snow melting, and pool and storage-tower heating.
