Evaporative Air Coolers

Significance of Evaporative Air Coolers

Summers have become so terribly hot in India, and cooling devices have become a necessity. It is almost impossible to survive these heatwaves without an efficient cooling system. If you want to invest in a cooling device, air coolers are very good options. No doubt there are other powerful devices like air conditioners, but if you want an eco-friendly and budget-friendly option, coolers are the best. Also, coolers are energy efficient which reduces the additional spike in the electricity bill. They work on the principle of evaporative cooling. Therefore, they are preferred over other cooling devices.

Evaporative air coolers are very efficient. They do not recirculate the stale warm air and do not use synthetic toxic refrigerants for the cooling process. Rather, they make use of the fresh outside air, cool it down with the help of water, and circulate it inside the room. So, the moisture is added to the dry air and it feels fresh and cool. So, evaporative coolers don’t just make the air cooler but also improve the air quality. Here is a detailed discussion about evaporative coolers, their features, and their benefits.


What is an Evaporative Cooler?

As the name suggests, evaporative coolers depend upon the evaporation of water for cooling. Water has a large entropy of vaporization. So, as it evaporates, it absorbs a large amount of heat in the process. So, as water transforms into water vapor, there is a significant drop in the temperature of air. As a result, the air is cooled efficiently using very less energy.

Evaporative coolers are also called swamp coolers. They have cooling pads, a water reservoir, and a fan. The thick layer of cooling pads retain water and provide the surface area for water evaporation. Bigger the surface area of pads, more is the cooling performance of the cooler. The water reservoir stores waters that is used for soaking the cooling pads. A water pump is standard part used in the air coolers. It helps in continuous circulation of water from reservoir tank on the cooling pads. The dry hot air from the surrounding is drawn into the cooler through the water-soaked cooling pads using the fan. The water evaporation helps in dropping the temperature of the air inside the cooler and this cool air is blown into the room using the fan. The air remains moisturized and is not dehydrated.

Additionally, air coolers may also contain parts like cotton mesh around the pads, which acts like air filter. These filters help in reducing allergens and control the growth of mold. As a result, the quality of the air is improved.


Types and Features of Evaporative Models

There are different types of evaporative coolers, which vary in design as well as features. The suitable model varies for every customer depending on each individual requirement. There are coolers available with many advanced features like auto air swing, float-valve, water level indicators and remote function. Here are some of them:


Design and Build

These days, the coolers with different designs are available. Some are elegant and stylish, whereas others are performance focused.

You can choose the one that suits the cooling requirement of your place.



Air coolers are available in different sizes, and you can choose the suitable model according to your requirements. If you have a large space, then you can go for desert coolers. These are kept outside and cool the air fast. For smaller area, you can choose room cooler or tower coolers. There are wheels attached to these coolers for easy movement that make them easily portable.


Speed control

Most of the air cooler models come with speed settings that helps you to adjust the speed of fan according to your requirements.


Uniform cooling

There are arrangements to move the louvers panels in some coolers, for the even cooling. It helps you to cool the room uniformly.


Inverter option

Some models of air coolers work even on inverter. It is significantly important feature especially in the places, where power outages are frequent in summers.


Advanced technology

Earlier, there were problems like water leakage and rusting in coolers. But, with advancement in design and technology, new materials are being used in coolers that prevent rusting and water leakage. These advancements make the coolers trouble free and increases the durability as well.


Benefits of Evaporative Coolers

There are different advantages of evaporative coolers. Some of them are:


Energy Efficiency

Evaporative coolers are energy efficient. They operate on lesser electricity as compared to air conditioners. As a result, you save a considerable amount of electricity.



Evaporative coolers are sustainable and eco-friendly options. They do not use harmful refrigerants or coolants that affect the environment. Rather, they use water for cooling, which does not cause any damage to the environment.


Health benefits

Cooler air does not dehydrate your skin or cause respiratory problems like sneezing, cough, and flu, which are quite common in air conditioners.



Coolers are very cost-effective options. The initial cost of purchase is low, and they are durable. Also, you need not spend a huge amount on their maintenance and servicing. So, they are the best air-cooling solution.
