5-266-12-048-005

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 12-inch shell, 48-inch shell length, and roughly 56-1/2 inches overall in a 4-pass arrangement. That works out to about 78 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-12-048-005. Material selection covers cast brass bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 300°F maximum temperature. Typical duty includes condensate cooling, oil cooling and snow melting, and hydronic HVAC converters.
