PME-E Open-Circuit Evaporative Cooling Tower

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

Safety is based on proper design, periodic maintenance, and effective water control. It is essential to prevent stagnation, ensure proper drainage, and maintain easy access to components for regular inspections.

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.

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.

In summary: Low installation and maintenance costs and very high cooling efficiency.

They vary according to type, capacity, and specific characteristics: from a few thousand euros to hundreds of thousands.

Wet cooling towers are known for their high energy and thermal efficiency, making them an ideal solution for dissipating excess heat in air-conditioning systems and industrial processes. Thanks to the principle of evaporative cooling, these technologies can achieve very low cooling temperatures while using minimal electrical energy and water. In many applications, these lower temperatures allow the overall system to operate with reduced power consumption, directly contributing to energy savings and a lower environmental impact.

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.
