WU44-24

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 4-inch diameter shell, 48-inch shell length, and roughly 52-7/8 inches overall in a 2-pass arrangement. That works out to about 9.19 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as WU44-24. 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, 150 PSI on the tube side, and 300°F maximum temperature. Installations range across oil cooling and snow melting, condensate cooling, and pool and storage-tower heating.
