Built around a removable U-tube bundle, this configuration delivers liquid-to-liquid heating and cooling for demanding service. Pumped boiler water circulates through the baffled shell against the tube-side fluid. The configuration measures 6 inches across the shell, 72-inch shell length, and roughly 76-1/8 inches overall in a 4-pass arrangement. That works out to about 26.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-06-072-005. As furnished, materials include cast brass 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. The series sees regular use in hydronic HVAC converters, pool and storage-tower heating, and condensate cooling.
