Beneficial features of evaporative coolers

You must have noticed how cool and comfortable it feels when you are in the vicinity of a waterfall. You really feel relieved on a hot summer day. That is, in essence, evaporative cooling!

To elaborate, the cooling or the fall in air temperature occurs when water evaporates. Evaporative coolers, commonly termed ‘swamp coolers’, make use of this cooling effect in your own home or small office.

There are several beneficial features of evaporative coolers that make them popular:

1.    Evaporative coolers utilise much less electricity and power than conventional air conditioners.2.    They have a minimal running cost.3.    Evaporative coolers emit fresh cooled air without any need for an exhaust hose.4.    Importantly, they do not use refrigerants like hydrochlorofluorocarbons (HCFCs) and chlorofluorcarbons (CFCs), which can greatly harm the ozone layer.

They are perfect for marquees, gymnasiums, factories, warehouses, shops, clubs, event venues, theatres, schools, halls and conservatories. This diverse usage demonstrates their high utility value. They can provide effective cooling in an area of 200 sq. ft. to 650 sq. ft.
