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. The configuration measures 8 inches across the shell, 48-inch shell length, and roughly 53 inches overall in a 4-pass arrangement. That works out to about 32 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-265-08-048-002. The series sees regular use in oil cooling and snow melting, pool and storage-tower heating, and hydronic HVAC converters.
