WU209-416

This configuration is a SU/WU unit built on a removable U-tube bundle for liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. The configuration measures 20 inches across the shell, 108-inch shell length, and roughly 129-1/8 inches overall in a 4-pass arrangement. That works out to about 565 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as WU209-416. The build specifies cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. Design ratings run to 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Typical duty includes pool and storage-tower heating, hydronic HVAC converters, and condensate cooling.
