Description
Technical Details

The educational unit (HT – 017) is designed to demonstrate the main components and principle of a wet cooling tower with forced ventilation.

Water is heated in a tank and transported by a pump to an atomizer.
The atomizer sprays the water to be cooled over the wet deck surface.
The water trickles from the top to the bottom along the wet deck surface whilst air flows from the bottom to the top.
The heat is transferred directly from the water to the air by convection and evaporation.
The air flow is generated by a fan and adjusted using a speed control.
The cooling column is transparent allowing clear observation of the wet deck surface and the trickling water.
The educational unit is supplied with digital displays to display all important process parameters are recorded (volumetric air flow rate, temperatures of air and water, air
Humidity, water flow rate) that are measured electronically.
The educational unit is provided with a software.
The measured values can also be transmitted directly to a PC via USB.
The changes of state of the air are represented in an h-x diagram.
Interchangeable cooling columns (not supplied by default) enable comparative studies.
The educational unit is provided with a DAQ software.
