Configured for liquid-to-liquid heating and cooling, this configuration carries the removable U-tube bundle construction that defines the SU/WU range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. The configuration measures 4 inches across the shell, 48-inch shell length, and roughly 52-7/8 inches overall in a 4-pass arrangement. That works out to about 9.19 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Typical duty includes condensate cooling, oil cooling and snow melting, and pool and storage-tower heating. This build is designated 5-266-04-048-002.
