DAC Worldwide’s Air-Cooled (Fin-Fan) Heat Exchanger Model (283) displays a scale version of an air-cooled, fin-tubed heat exchanger used in refineries, petro-chemical plants, gas treating plants, power plants, and more. Air-cooled heat exchangers (ACHE), also called fin-fans or air coolers, cool or condense hot fluid in industrial process applications by passing ambient air over and between tubes used to move the fluid. The heated air is then discharged into the atmosphere.

This petrochemical training system demonstrates in high fidelity the operating principles, construction, and basic maintenance air-cooled heat exchangers. Components shown in great detail include fin-tubes, fan blades, fan ring, shrouds, drive assembly with motor, header boxes with cover plates and pass partitions, plenum/cowling, flanged connections, support structure, as well as secondary vent and drain connections. This model includes two segments, one depicting an induced-draft arrangement, and a second depicting a forced-draft arrangement.
