For liquid-to-liquid heating and cooling, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 4-inch shell unit, 84-inch shell length, and roughly 88-7/8 inches overall in a 4-pass arrangement. That works out to about 16.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-04-084-005. The build specifies 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 pool and storage-tower heating, condensate cooling, and hydronic HVAC converters.
