A removable U-tube bundle gives this configuration the thermal and mechanical margin expected of SU/WU equipment in liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 12-inch diameter shell, 72-inch shell length, and roughly 80-1/2 inches overall in a 6-pass arrangement. That works out to about 103 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-12-072-003. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. Common applications are hydronic HVAC converters, pool and storage-tower heating, and oil cooling and snow melting.
