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. Dimensionally it is a 10-inch shell unit, 72-inch shell length, and roughly 77 inches overall in a 4-pass arrangement. That works out to about 82 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, copper tubes, and steel 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 5-265-10-072-002. Typical duty includes oil cooling and snow melting, pool and storage-tower heating, and hydronic HVAC converters.
