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. Physically, the unit runs a 10-inch shell, 72-inch shell length, and roughly 77 inches overall in a 4-pass arrangement. That works out to about 82 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-10-072-002. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 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.
