Evaporative air conditioning uses the natural process of evaporation to cool the air.

A pump circulates water from a reservoir onto a cooling pad, and a fan draws fresh air from outside through the saturated pad. As the air passes through the pad, it’s cooled by evaporation.

This approach to cooling may be simple, but it’s also highly effective.

It’s also much quieter, cheaper and healthier than traditional air conditioning.

A traditional air conditioner recirculates the air in an enclosed space. As a result, the air indoors may become stale, with reduced oxygen levels. It can also dry the eyes and aggravate allergy symptoms.

Unlike standard air conditioners, evaporative coolers continually circulate fresh air throughout your home or office.

They gently cool and humidify air that’s drawn in from outside. They also clean this air, filtering it through water to remove dust, pollen and other outdoor contaminants.

There’s no need to close windows and doors. As well as filtering the air that passes through it, an evaporative cooler maintains a positive pressure in the building. This helps keep dust, pollen and pollution from entering through open windows and doors.

Evaporative cooling is one of the most cost-effective means of cooling air. It achieves a saving of up to 87% of energy costs compared with traditional air conditioning.

Evaporative cooling uses a natural cooling process rather than refrigerant gases, which are harmful to the environment and can pose health hazards for people.

Evaporative coolers are equally suitable in both homes and public and commercial spaces, such as shops, showrooms, schools and factories.
