WU268-2

Built around a removable U-tube bundle, this configuration delivers liquid-to-liquid heating and cooling for demanding service. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Physically, the unit runs a 26-inch shell, 96-inch shell length, and roughly 146 inches overall in a 2-pass arrangement. That works out to about 935 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in oil cooling and snow melting, pool and storage-tower heating, and hydronic HVAC converters. This build is designated WU268-2.
