WU166-65

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. Physically, the unit runs a 16-inch shell, 72-inch shell length, and roughly 81-3/4 inches overall in a 6-pass arrangement. It carries 3/4-inch O.D. tubes. Material selection covers cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. Design ratings run to 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. This build is designated WU166-65. Common applications are oil cooling and snow melting, condensate cooling, and hydronic HVAC converters.
