Air coolers are heat exchangers which the process fluid cools with airflow. In these exchangers, hot fluid is distributed within a series of tubes that are arranged horizontally. The outer sides of these tubes are equipped with a fin to increase the heat transfer surface between vapors and cool air. These heat exchangers are cross-current or co-current based on flow profile, which the required air flow is provided by a fan. Induced Air coolers are those that the fans stay above the bundles otherwise will called as Forced Air Coolers. On the same air flow distribution, the Induced types has more efficiency, the other important fact about these exchangers is that water plays no role and will reduce the cost by itself. Air coolers are used in many units such as Amine, PTA, MTBE, EDC / VCN.

Air Cooled Heat Exchangers

Air cooled heat exchangers can be a good choice when cooling water is not available. Shegeftafzar can design and build Air Cooled Heat Exchangers and Condensers customized for each application.
