5-266-06-048-002

Built around a removable U-tube bundle, 5-266-06-048-002 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 6-inch shell, 48-inch shell length, and roughly 52-1/8 inches overall in a 4-pass arrangement. That works out to about 17.39 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers 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. Typical duty includes hydronic HVAC converters, pool and storage-tower heating, and condensate cooling. Optional stainless shells, 90/10 copper-nickel tubes, and cast brass or bronze bonnets suit aggressive or brackish water service.
