Configured for liquid-to-liquid heating and cooling, this configuration carries the removable U-tube bundle construction that defines the SU/WU range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 4-inch diameter shell, 84-inch shell length, and roughly 88-7/8 inches overall in a 4-pass arrangement. That works out to about 16.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-265-04-084-002. Common applications are condensate cooling, hydronic HVAC converters, and pool and storage-tower heating.
