The ACA aftercooler platform pairs a removable straight-tube bundle with proven shell-side baffling, and this configuration applies that design to compressed air aftercooling. Hot compressed air enters the tubes while cooling water counterflows through the shell, condensing moisture for removal downstream. The configuration measures 3 inches across the shell, 48-inch shell length in a 1-pass arrangement. It carries 1/4-inch O.D. tubes. That combination is cataloged as 5-155-03-051-002. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 300°F maximum temperature. Typical duty includes compressed air dryer pre-cooling, pneumatic tool and instrument air conditioning, and moisture and oil removal from plant air.
