The SU/WU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 8-inch diameter shell, 72-inch shell length, and roughly 77 inches overall in a 4-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 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. This build is designated 5-266-08-072-005. Common applications are oil cooling and snow melting, hydronic HVAC converters, and condensate cooling.
