5-266-12-084-003

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 12 inches across the shell, 84-inch shell length, and roughly 92-1/2 inches overall in a 6-pass arrangement. That works out to about 121 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, N/A on the tube side, and 300°F maximum temperature. This build is designated 5-266-12-084-003. The series sees regular use in oil cooling and snow melting, pool and storage-tower heating, and condensate cooling.
