Air Cooler is a heat exchanger used to cool process fluids (liquid phase/gas phase) by utilizing atmospheric air as a cooling medium. Because it cools the fluid in a closed system (closed-loop), the risk of contamination and corrosion in process fluids can be minimized. This device usually consists of a collection of finned tubes (finned tubes) and a fan/fanthat flows air through the finned tubes (finned tubes) to remove heat.
