Air coolers (evaporators) are the main parts of any refrigerated or freezing chambers. They are installed inside the chamber for its cooling. The chilled liquid freon enters the evaporator from exteral unit. Passing through the radiator of air cooler, Freon takes the heat generated by the products stored in the chamber and then removes the heat from the chamber. The fans (from 2 to 5 pcs) are installed in air coolers (evaporators) for better heat exchange.
