WU68-43

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. Dimensionally it is a 6-inch shell unit, 96-inch shell length, and roughly 100-1/8 inches overall in a 4-pass arrangement. That works out to about 36.2 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as WU68-43. 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, 150 PSI on the tube side, and 300°F maximum temperature.
