10 things you need to know about evaporative coolers

Just like a sea breeze keeps you cool at the beach on a hot day, an evaporative cooler uses the power of evaporation to cool your home. On a hot day by the seaside, the movement of air over the ocean causes water to evaporate, absorbing some heat from the air. During this process, the air temperature is lowered and the result is a cooling sea breeze.

In an evaporative cooler, hot and dry outside air is pumped through water-soaked pads called Chillcel® pads. As the air blows through the Chillcel pads, the water is evaporated and the heat in the air is absorbed, which lowers the air temperature. A fan then pushes the cool air through the ducting system.

There’s never been a better time to invest in an evaporative cooler. Going evaporative is simple to maintain and operate and offers superior product performance. With energy prices escalating and Australian summers typically involving heat waves, evaporative air conditioning offers a significant and increasing edge on reverse cycle. In particular, when it comes to energy efficiency, healthier air flow, performance and lifestyle. Below are 10 things that you may not know about evaporative coolers:

1. 100% fresh air

The air is 100% fresh air. In an evaporative cooler, the evaporative process relies on airflow, with cool air entering through ducts and then exiting via open doors or windows. Only 100% fresh air is circulating, rather than stale and recycled air. Furthermore, refrigerated cooling can not only cause the air to become dry inside a home, but it also uses chemicals which can damage the environment. In comparison, evaporative cooling is based completely on natural processes which cools air using water and with no chemicals involved. Compared to refrigerated air conditioning, the air released from evaporative coolers is never re-circulated, and is constantly replaced with fresh air – meaning your eyes and throat won’t become irritated and people with respiratory and health issues can enjoy their time indoors.

2. Good for the environment

Evaporative coolers are good for the environment. Every time a customer chooses an evaporative cooler, the benefits for the environment are significant. For example the Australian manufactured Breezair evaporative cooler, has been shown to produce about ** 20% of the carbon emissions produced by a standard refrigerated air conditioning system. In fact evaporative coolers are one of the most environmentally friendly methods of cooling available,because evaporative cooling isbased on a natural technology. Evaporative cooling systems contain no harmful synthetic refrigerants. In addition to the previous point, Lower electricity usage with evaporative air conditioning. The only power-consuming components of an evaporative cooler are the fan, electronic control and a small water pump. As a result, evaporative cooling running costs are low, using up to 80 per cent less energy than refrigerated air conditioning*** which means less fossil fuels such as coal and natural gas are consumed in the production of electricity.

3. You can leave your windows and doors open

This is especially beneficial if you are entertaining guests outside, or people who have pets and children who like to frequently come in and out throughout the day. One of the great advantages of an evaporative cooler is that doors and windows can be left open. That convenience doesn’t have to compromise your home security because Security Relief Vents can be fitted into a ceiling – which means you can sleep easy with all your doors and windows locked while the system runs overnight. In trying to determine which technology suits a home and lifestyle, the cost to operate each whole of home system should be closely examined in addition to the features and benefits. For example if you do a lot of outdoor entertaining in summer, evaporative cooling has the ability to cool outdoor entertaining areas, perfectly complementing Australia’s alfresco living. On the other hand, open plan outdoor areas can’t be cooled using a reverse cycle air conditioner.

4. Low Water Usage

Evaporative air coolers use a small amount of water, in many instances using almost 98% less water than a shower over a year. A Breezair evaporative air cooler for example, uses around 15 litres of water a day averaged over a year. This is far less than a front loading washing machine which uses around 60 litres of water for one wash, or a top loading washing machine that uses on average 150 litres of water for one wash. ****

5. Whisper Quiet Operation

In the dead of night there’s nothing more annoying than a noisy hum of an air conditioner. Seeley International’s evaporative air conditioners have a reputation for being exceptionally quiet, so you won’t hear a thing as you sleep, particularly the Breezair which is renowned for being whisper quiet.

6. Moisturises the air

Adds moisture to the air – Evaporative air conditioning can also help to slightly increase the amount of moisture in the air. This is especially beneficial for people living in dryer climates who can find it difficult to breathe or experience dry and cracked skin when using refrigerated options.

7. Australian designed, made and owned

For Australian home owners investigating a new air conditioner, it makes sense to examine the locally manufactured and world leading Breezair evaporative cooling system built to withstand Australia’s harsh hot and dry climate.

8. Highly efficient

At a time when Australians are faced with high energy costs, there is plenty of debate when it comes to evaporative vs refrigerated air conditioning running costs. The reality is that one of the most significant benefits of evaporative air conditioning is that running costs are far lower than refrigerated options. Modern and innovative evaporative cooling products see savvy consumers save up to 80% on energy bills when compared to a reverse cycle air conditioner.***

9. Puts you in control

Effortless air conditioning, using your voice. With the MagIQtouch® Wi-Fi smart voice skill and Alexa, you can run your MagIQtouch® Wi-Fi compatible heating and cooling with your voice or remotely using the MagIQtouch® Wi-Fi smart app on your smart devices. The MagIQtouch® Smart home integration skill requires a MagIQtouch® Wi-Fi wall controller, Wi-Fi smart app controller and MagIQtouch® account to operate.

10. Easy maintenance

Easy maintenance helps to keep costs down. Easy and regular service by a qualified technician from time to time will ensure that an evaporative air conditioner continues to run at its peak efficiency and maintain low evaporative cooling costs. Australia’s own Breezair, Braemar and Coolair ranges have locally designed and manufactured cooling pads specifically aimed at maximising cooling in our harsh summer climate. To make things easier and also improve efficiency, some evaporative air conditioners also have automated pad rinse technology and seasonal maintenance alerts. It helps too that evaporative coolers are also made of a hard wearing, easy to maintain, highly durable and non-corrosive plastic outer casing, are light weight, easy to install and maintain. These hard wearing non-corrosive casings will not rust or corrode contributing to their long life and in turn contributing to savings on not having to replace the casing.
