ACA66-52

Configured for compressed air aftercooling, ACA66-52 carries the removable straight-tube bundle construction that defines the ACA aftercooler range. Hot compressed air enters the tubes while cooling water counterflows through the shell, condensing moisture for removal downstream. Its envelope centers on a 6-inch diameter shell, 72-inch shell length in a 1-pass arrangement. It carries 1/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. On the ratings side, expect 300°F maximum temperature. The series sees regular use in pneumatic tool and instrument air conditioning, moisture and oil removal from plant air, and compressed air dryer pre-cooling. A floating rear tubesheet lets the bundle expand freely and pull for cleaning, and full-size air connections hold pressure drop down.
