5-155-08-081-001

For compressed air aftercooling, the ACA aftercooler line offers a removable straight-tube bundle design; 5-155-08-081-001 sits within that range. Hot compressed air enters the tubes while cooling water counterflows through the shell, condensing moisture for removal downstream. Dimensionally it is a 8-inch shell unit, 72-inch shell length in a 1-pass arrangement. It carries 1/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, copper tubes, and steel tubesheets. On the ratings side, expect 300°F maximum temperature. Installations range across compressor discharge aftercooling, compressed air dryer pre-cooling, and pneumatic tool and instrument air conditioning. A floating rear tubesheet lets the bundle expand freely and pull for cleaning, and full-size air connections hold pressure drop down.
