Evaporative Cooling Systems

The difference between the two systems lies in the different type of circuit exploited for cooling the process fluid.

An evaporative condenser condenses the refrigerant gas inside coils that are wetted by sprayed water and cooled by an airflow. According to the evaporative cooling principle, when a small portion of water evaporates, heat is dissipated and the refrigerant condenses.

In direct evaporative cooling (open-circuit evaporative tower), the process water to be cooled is introduced into the tower and comes into direct contact with the outside air. The water evaporates directly into the air, removing heat and lowering its temperature — leveraging a simple natural principle: the forced evaporation of a small amount of water causes a temperature drop in the main water mass.

Both open-circuit and closed-circuit towers exploit a very efficient operating principle: forced evaporation of a minimum amount of water causes a lowering of the temperature of the main water mass.

All evaporative cooling systems use the evaporation of a small amount of water to lower the temperature of the larger mass of water. There are three main types of evaporative cooling systems: open circuit cooling towers, closed circuit cooling towers, and evaporative condensers.

Both systems use water, but in different amounts, in different ways, and with different levels of efficiency. The direct evaporative

In summary: high cooling efficiency, low operating costs, and others related to the operation of the technology.
