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 10-inch shell, 84-inch shell length, and roughly 89 inches overall in a 6-pass arrangement. That works out to about 80 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. The unit is rated for 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. Installations range across pool and storage-tower heating, oil cooling and snow melting, and hydronic HVAC converters. This build is designated 5-266-10-084-003.
