ACA66-64

Configured for compressed air aftercooling, this configuration 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. Dimensionally it is a 6-inch shell unit, 72-inch shell length in a 1-pass arrangement. It carries 1/4-inch O.D. tubes. That combination is cataloged as ACA66-64. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are 300°F maximum temperature. Installations range across compressed air dryer pre-cooling, moisture and oil removal from plant air, and compressor discharge aftercooling. A floating rear tubesheet lets the bundle expand freely and pull for cleaning, and full-size air connections hold pressure drop down.
