WU205-413

The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 20-inch shell unit, 60-inch shell length, and roughly 81-1/8 inches overall in a 4-pass arrangement. That works out to about 314 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as WU205-413. 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. Installations range across hydronic HVAC converters, condensate cooling, and pool and storage-tower heating.
