WU166-610

For liquid-to-liquid heating and cooling, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 16-inch shell unit, 72-inch shell length, and roughly 81-3/4 inches overall in a 6-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as WU166-610. Standard construction uses 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. Common applications are oil cooling and snow melting, hydronic HVAC converters, and pool and storage-tower heating.
