5-266-10-108-005

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. The configuration measures 10 inches across the shell, 108-inch shell length, and roughly 113 inches overall in a 4-pass arrangement. That works out to about 124 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass 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. Typical duty includes pool and storage-tower heating, oil cooling and snow melting, and hydronic HVAC converters. This build is designated 5-266-10-108-005.
