WATER COOLING TOWER
The trainer is designed to demonstrate the most widespread cooling method in industry.
The demonstrated method shows the cooling of hot water to room temperature.
Air at room temperature is introduced by a fan from the lower part of the system at the bottom of the tower.
While hot water is sprayed in the upper section of the tower, hot water cools down until it reaches room temperature, then it is reheated and the process starts again.
The unit is supplied with a personal computer.
