WU128-66

For liquid-to-liquid heating and cooling, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 12-inch diameter shell, 96-inch shell length, and roughly 104-1/2 inches overall in a 6-pass arrangement. That works out to about 139 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as WU128-66. Standard construction uses cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. The unit is rated for 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature.
