WU169-210

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. The configuration measures 16 inches across the shell, 108-inch shell length, and roughly 117-3/4 inches overall in a 2-pass arrangement. That works out to about 342 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers 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, 125 PSI on the tube side, and 300°F maximum temperature. Installations range across pool and storage-tower heating, oil cooling and snow melting, and condensate cooling. This build is designated WU169-210.
