Evaporative coolers (also known as swamp coolers) draw hot outside air through wet cooling pads, where water evaporates and cools the air. This system is very energy-efficient compared to refrigeration-based cooling and is eco-friendly. It's suitable for factories, warehouses, and open spaces, particularly in dry regions of Nepal like western Terai.

Key Features:

• Low electricity use

• Simple operation and maintenance

• Increases humidity (not suitable for humid areas)

• Great for semi-open environments
