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 10-inch shell unit, 72-inch shell length, and roughly 77 inches overall in a 6-pass arrangement. That works out to about 68 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. This build is designated 5-266-10-072-003. Installations range across oil cooling and snow melting, condensate cooling, and pool and storage-tower heating.
