5-265-12-048-003

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. Dimensionally it is a 12-inch shell unit, 48-inch shell length, and roughly 56-1/2 inches overall in a 6-pass arrangement. That works out to about 68 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. Design ratings run to 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. This build is designated 5-265-12-048-003. Typical duty includes hydronic HVAC converters, pool and storage-tower heating, and condensate cooling.
