For compressed air aftercooling, the ACA aftercooler line offers a removable straight-tube bundle design; this configuration 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 3-inch shell unit, 48-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. This build is designated 5-155-03-051-003. The series sees regular use in moisture and oil removal from plant air, compressor discharge aftercooling, 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.
