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 12 inches across the shell, 72-inch shell length, and roughly 80-1/2 inches overall in a 2-pass arrangement. That works out to about 126 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast brass 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 5-266-12-072-004. The series sees regular use in condensate cooling, pool and storage-tower heating, and hydronic HVAC converters.
