The evaporative cooler is a very simple device, which serves to cool water by direct exchange with air.
There are different types of evaporative towers:
- induced, with suction fans
- forced, using forced ventilation
- counter flow, with countercurrent water and air flow
- cross flow, that uses a crossing flow of water and air
in any case all of these machines work using the same concept.
The counter-flow type is the most widely used, whether it be forced or induced, because it presents greater functioning efficiency.
