5-266-10-084-002

This configuration is a SU/WU unit built on a removable U-tube bundle for liquid-to-liquid heating and cooling. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Physically, the unit runs a 10-inch shell, 84-inch shell length, and roughly 89 inches overall in a 4-pass arrangement. That works out to about 96 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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-266-10-084-002. The series sees regular use in hydronic HVAC converters, condensate cooling, and oil cooling and snow melting.
