A removable U-tube bundle gives this configuration the thermal and mechanical margin expected of SU/WU equipment in liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 8-inch shell unit, 72-inch shell length, and roughly 77 inches overall in a 2-pass arrangement. That works out to about 49 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. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are pool and storage-tower heating, condensate cooling, and hydronic HVAC converters. This build is designated 5-265-08-072-001.
