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. Physically, the unit runs a 6-inch shell, 36-inch shell length, and roughly 40-1/8 inches overall in a 2-pass arrangement. That works out to about 12.7 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. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Typical duty includes oil cooling and snow melting, pool and storage-tower heating, and condensate cooling. This build is designated 5-265-06-036-001.
