5-266-08-084-002

Configured for liquid-to-liquid heating and cooling, 5-266-08-084-002 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. Dimensionally it is a 8-inch shell unit, 84-inch shell length, and roughly 89 inches overall in a 4-pass arrangement. That works out to about 58 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are pool and storage-tower heating, oil cooling and snow melting, and hydronic HVAC converters.
