5-266-10-120-002

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 10-inch shell unit, 120-inch shell length, and roughly 125 inches overall in a 4-pass arrangement. That works out to about 138 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-10-120-002. 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, hydronic HVAC converters, and oil cooling and snow melting.
