WU207-416

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 20-inch diameter shell, 84-inch shell length, and roughly 105-1/8 inches overall in a 4-pass arrangement. That works out to about 439 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as WU207-416. The build specifies cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. Operating limits are 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Installations range across hydronic HVAC converters, pool and storage-tower heating, and oil cooling and snow melting.
