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, 108-inch shell length, and roughly 116-1/2 inches overall in a 4-pass arrangement. That works out to about 180 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. On the ratings side, expect 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in hydronic HVAC converters, condensate cooling, and pool and storage-tower heating. This build is designated 5-266-12-108-002.
