ACFR-316

A fixed-tubesheet bundle gives this configuration the thermal and mechanical margin expected of ACFR aftercooler equipment in compressed air aftercooling. Compressed air passes through the tubes against cooling water in the baffled shell, and the tube interiors clean easily from either end. The configuration measures 3-1/2 inches across the shell, 50-inch shell length, and roughly 50 inches overall in a 1-pass arrangement. That works out to about 4.2 square feet of heat transfer surface on 1/4-inch O.D. tubes. That combination is cataloged as ACFR-316. The build specifies 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, instrument and shop air conditioning, and small and mid-size compressor packages.
