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. The configuration measures 6 inches across the shell, 36-inch shell length, and roughly 40-1/8 inches overall in a 2-pass arrangement. That works out to about 12.7 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-06-036-004. As furnished, materials include cast brass 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, hydronic HVAC converters, and oil cooling and snow melting.
