WU145-64

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. Its envelope centers on a 14-inch diameter shell, 60-inch shell length, and roughly 69-1/8 inches overall in a 6-pass arrangement. It carries 3/4-inch O.D. tubes. As furnished, materials include cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. The unit is rated for 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, oil cooling and snow melting, and pool and storage-tower heating. This build is designated WU145-64.
