Evaporative Air Cooler

An evaporative air cooler is an effective cooling system for dry climates. It cools air by circulating it through wet pads and relies on the latent heat of water to evaporate moisture, which is less energy-intensive than compressor-based cooling systems.

Evaporative cooling units are not ideal for humid areas because high humidity prevents the evaporation of water and thus reduces their cooling effect. Humid climates should choose air conditioning or another cooling strategy.

Cooling Capacity

Evaporative coolers cool homes by circulating a mixture of air and water, cooling the air by the evaporation process. As this happens, the air is also filtered and humidified, making it ideal for dry climates. These features make evaporative air coolers more versatile than traditional fans and air conditioners. They can be used in many different applications, from cooling whole houses to commercial settings such as schools and waiting rooms.

The evaporative cooling system in this ducted model from Seeley International works in two stages to achieve the desired room temperature. In the first stage, warm air passes through a heat exchanger to pre-cool it without adding humidity. The second stage is the evaporative cooling process itself. The evaporative cooling pads absorb the moisture in the hot, direct air flow, which then carries the water and humidity through the system to the ceiling. The cooled air is then distributed throughout the house by the fan.

This is the largest evaporative cooler in our guide, with an impressive CFM of 525 and three fan speeds. It also has water pump and oscillation settings, as well as a remote that lets you control all of these functions from a distance. Its water tank holds 7.9 gallons of water and can be manually refilled. The cooler uses less Evaporative air cooler than one-third of the energy required to run a mid-sized window air conditioner, making it an environmentally friendly option.

Energy Efficiency

Evaporative air coolers are a lot more energy efficient than traditional AC systems. They consume up to 75 per cent less electricity. This makes them ideal for areas that experience hot and dry climatic conditions. This is because evaporative coolers add moisture to the air, which makes it easier to breathe in. Moreover, they also prevent the skin from drying up. This is unlike standard AC units that remove the moisture from the air, which causes breathing difficulties and dries up the skin.

Most evaporative coolers use very low power to operate, and the amount of electricity they consume depends on their size and features. Some of the models in this guide use as little as 18W, which is a fraction of what you would use when running a mid-sized window air conditioner.

However, it’s important to keep in mind that evaporative cooling systems can only cool down rooms with a high humidity level. This is because the humidity level has an impact on how much water vapour can be absorbed by the air, and it’s essential for the cooling process to take place.

Besides, evaporative coolers don’t emit any refrigerants, which is great news for the environment as they don’t deplete the earth’s ozone layer. As a result, they are a safer alternative to standard air conditioning systems that emit toxic chemicals.

Noise Levels

Evaporative coolers don’t use coils and chemicals to cool the Evaporative air cooler air, so they aren’t nearly as noisy as an AC. This makes them ideal for rooms where audible tones are not welcome.

Unlike an AC that circulates hot, dry air, an evaporative air cooler pulls in air and passes it through cooling pads that are saturated with water. The water evaporates into the air as the fan moves over it, cools the air, and is then blown into the room. The quiet operation of an evaporative cooler is due to its lack of moving parts and the absence of coils that expand and contract as they do in an AC.

Even large portable evaporative coolers like the iCool 5000 can run quietly enough to be able to work in a home or office environment. The iCool 5000 can cool an area up to 540 square feet, which is more than enough to cool the average bedroom. It can also be plugged into a standard wall outlet, making it an affordable option for businesses that want to keep their customers and employees comfortable without breaking the bank on energy costs.

The iCool 5000 is also quiet, as it uses a slow-moving fan with lubricated bearings that move at low RPMs and emit less noise than a typical industrial fan. It also doesn’t require the use of chemicals or coils, so it is a good choice for people who are concerned about the environmental impact of their air cooling solution.


Evaporative coolers need little maintenance, but there are some important things that you should do to keep them working well. You will need to clean your evaporative cooling pads regularly (every week or two) and drain the tank on a weekly basis. This will prevent the water inside from becoming contaminated with terrible contaminants like bacteria, germs and mosquitoes. You can use white vinegar and water to clean the tank, but some people also choose to buy a water treatment tablet for their tank to make cleaning easier.

In addition, you should check the water reservoir on a daily basis and replenish it when needed. This will ensure that the water used for evaporative cooling is fresh and helps reduce the buildup of hard-water deposits and mineral deposits on the evaporative cooling pads. It is a good idea to change the filters on a regular basis as well.

When it’s time to prepare the evaporative air cooler for the winter months, you should disconnect it and drain it thoroughly. This will help to avoid the growth of bacteria and other issues that can affect how well the evaporative air cooler works. You should also clean the water reservoir, filters and the unit exterior, allowing everything to dry before storing it. Finally, you should lubricate the evaporative air cooler motor and blower bearings, as this will improve performance.
