WU47-24

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 4-inch shell unit, 84-inch shell length, and roughly 88-7/8 inches overall in a 2-pass arrangement. That works out to about 16.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers 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. Common applications are condensate cooling, hydronic HVAC converters, and oil cooling and snow melting. This build is designated WU47-24.
