Built around a removable U-tube bundle, this configuration delivers liquid-to-liquid heating and cooling for demanding service. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 6-inch diameter shell, 72-inch shell length, and roughly 76-1/8 inches overall in a 2-pass arrangement. That works out to about 26.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-06-072-001. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Installations range across pool and storage-tower heating, hydronic HVAC converters, and oil cooling and snow melting.
