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 6-inch shell, 84-inch shell length, and roughly 88-1/8 inches overall in a 2-pass arrangement. That works out to about 31.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers 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. This build is designated 5-266-06-084-001. The series sees regular use in hydronic HVAC converters, pool and storage-tower heating, and oil cooling and snow melting.
