WU108-65

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. Dimensionally it is a 10-inch shell unit, 96-inch shell length, and roughly 101 inches overall in a 6-pass arrangement. That works out to about 92 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include 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. Common applications are pool and storage-tower heating, hydronic HVAC converters, and condensate cooling. This build is designated WU108-65.
