ACA109-136

this configuration is a ACA aftercooler unit built on a removable straight-tube bundle for compressed air aftercooling. Hot compressed air enters the tubes while cooling water counterflows through the shell, condensing moisture for removal downstream. Its envelope centers on a 10-inch diameter shell, 108-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. Design ratings run to 300°F maximum temperature. The series sees regular use in moisture and oil removal from plant air, compressed air dryer pre-cooling, 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. The resulting model number is ACA109-136.
