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. Its envelope centers on a 4-inch diameter shell, 36-inch shell length, and roughly 40-7/8 inches overall in a 4-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-04-036-005. Material selection covers cast brass bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are hydronic HVAC converters, pool and storage-tower heating, and oil cooling and snow melting.
