Desert Cooler Trainer works on the principle of evaporative cooling.  These are mostly used in dry regions. It has a fan that takes in air from the atmosphere through pads specifically made for desert coolers. The difference in DBT & WBT at inlet and outlet can be measured hence the RH from the charts. The amount of water evaporated can be calculated by knowing the water level difference in the reservoir. 

SPECIFICATIONS:

1. Fan is attached to 1/2 HP motor.

2. Air Cooler Pump is fitted for the circulation of water

3. DBT & WBT Measuring Thermometer at inlet and outlet.

4. Orifice meter with manometer to measure the air flow.
