This configuration is a SU/WU unit built on a removable U-tube bundle for liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 8-inch shell unit, 60-inch shell length, and roughly 65 inches overall in a 6-pass arrangement. That works out to about 33 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. Installations range across hydronic HVAC converters, oil cooling and snow melting, and condensate cooling. This build is designated 5-266-08-060-003.
