For liquid-to-liquid heating and cooling, the SU/WU line offers a removable U-tube bundle design; 5-265-04-072-002 sits within that range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 4-inch diameter shell, 72-inch shell length, and roughly 76-7/8 inches overall in a 4-pass arrangement. That works out to about 13.9 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are oil cooling and snow melting, hydronic HVAC converters, and condensate cooling.
