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 8-inch shell, 84-inch shell length, and roughly 89 inches overall in a 6-pass arrangement. That works out to about 48 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-08-084-003. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 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, oil cooling and snow melting, and hydronic HVAC converters.
