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. Dimensionally it is a 8-5/8-inch shell unit, 50-inch shell length, and roughly 50 inches overall in a 1-pass arrangement. That works out to about 40 square feet of heat transfer surface on 1/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 300°F maximum temperature. Installations range across moisture and oil removal from plant air, small and mid-size compressor packages, and instrument and shop air conditioning. This build is designated 5-005-08-050-004.
