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. The configuration measures 6 inches across the shell, 36-inch shell length, and roughly 40-1/8 inches overall in a 2-pass arrangement. That works out to about 12.7 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-266-06-036-001. Common applications are condensate cooling, pool and storage-tower heating, and hydronic HVAC converters.
