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. Physically, the unit runs a 6-inch shell, 84-inch shell length, and roughly 88-1/8 inches overall in a 4-pass arrangement. That works out to about 31.5 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. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Typical duty includes pool and storage-tower heating, condensate cooling, and hydronic HVAC converters. This build is designated 5-266-06-084-002.
