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. The configuration measures 6 inches across the shell, 72-inch shell length, and roughly 76-1/8 inches overall in a 6-pass arrangement. That works out to about 20.2 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in condensate cooling, oil cooling and snow melting, and pool and storage-tower heating. This build is designated 5-266-06-072-003.
