Configured for liquid-to-liquid heating and cooling, this configuration carries the removable U-tube bundle construction that defines the SU/WU range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 8-inch shell unit, 72-inch shell length, and roughly 77 inches overall in a 2-pass arrangement. That works out to about 49 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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-266-08-072-001. Installations range across oil cooling and snow melting, condensate cooling, and hydronic HVAC converters.
