This configuration is a SU/WU unit built on a removable U-tube bundle for liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 10-inch diameter shell, 48-inch shell length, and roughly 53 inches overall in a 2-pass arrangement. That works out to about 56 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-266-10-048-001. Installations range across pool and storage-tower heating, hydronic HVAC converters, and oil cooling and snow melting.
