WU186-612

This configuration is a SU/WU unit built on a removable U-tube bundle for liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Its envelope centers on a 18-inch diameter shell, 72-inch shell length, and roughly 89-1/2 inches overall in a 6-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as WU186-612. As furnished, materials include cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. Operating limits are 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. The series sees regular use in hydronic HVAC converters, pool and storage-tower heating, and oil cooling and snow melting.
