What is an evaporative cooler?

During the summer, heat waves and extreme temperatures make air cooling and ventilation devices increasingly indispensable in our daily lives. To combat this, various devices are currently available on the market, including fans, misting fans, evaporative coolers (also known as swamp coolers), air conditioners, and many others. The advantages and disadvantages of each of these products are distinct. In recent years, the presence of evaporative cooling products has been notorious, but what is an evaporative air cooler exactly? And how does it work? We reveal how it works and what benefits it offers.

How does the evaporative cooler work?

An evaporative cooler is not the same as an air conditioner! Unlike conventional coolers and air conditioners, evaporative coolers are more ecological and environmentally friendly, as they do not require compressors or refrigerants. Swamp coolers work by using a mechanism whereby, when warm air encounters water, an exchange of heat and cold takes place; the water naturally absorbs the thermal energy and evaporates. After evaporation, a cooling effect occurs. Depending on the changes in ambient temperature and relative humidity, this effect will vary. The greater the room temperature, and the lower the relative humidity, the more noticeable the cooling effect produced by the swamp cooler.

The cooling effect mimics a waterfall; the water from the tank is drawn up into the filter pads by a pump, cyclically drenching them as warm air from the outside flows through the damped pads, causing an evaporative cooling effect as it passes through them. Cooled air is expelled by the powerful fan, significantly reducing the ambient temperature.

Various stores offer water mist sprayers to cool down by blowing water mist onto the skin, giving the body a feeling of freshness. A further advantage worth mentioning is its air-purifying effect. Like rain in nature, as the air passes through the water, it absorbs a certain percentage of dust.

Advantages of an evaporative cooler

• Ecological
• Easily transportable thanks to its swivel casters
• Suitable for indoor and outdoor use
• Energy and cost saving
• No complicated installation is required. Just plug it into your mains for immediate use.
  

The portable evaporative cooler was developed without a refrigerant or compressor, so it consumes less energy and doesn’t emit hot air. The included wheel kit makes it easy to move the unit wherever you want.

How to use the device and better its function?

The control panel of the swamp cooler typically has the functions of wind speed, cold air, and oscillation. By turning on the speed switch, the unit will start to operate, and you can select the air speed between Low / Medium / High according to your need. Adjust the cooling mode to start the cooling action. The horizontal swing automatic function causes the louvers to constantly change direction for maximum cooling efficiency, allowing the air outlet to have a wider angle.

Water can be refilled from the tank using the hose. For safety, please remember to switch off the appliance before adding water. We recommend that the water tank be filled to 70% to avoid spillage while moving the unit. Here are some tips to maximize the cooling effect of your swamp cooler. Add ice water and ice cubes or empty PET bottles to freeze the water and place them in the tank to improve the cooling effect.

Where should you install the evaporative cooler?

In terms of the application of evaporative coolers, these devices are suitable for use in any open and/or semi-open place with good air circulation, such as homes, factories, churches, restaurants, food courts, small format stores, department stores, auto repair shops, all types of events, etc., and many other places where you want to renew and clean the air. It is recommended to be placed near a window or door, so ventilation can easily circulate inside.

Upkeep and Cleaning of the evaporative cooler

We suggest cleaning and draining the water from the tank and refilling it weekly with clean water to reduce mineral build-up. If there are still traces of mineral build-up on the cooling pad, please remove it and clean it gently with water. To obtain the best results, after each use, within 15 minutes before turning off the unit, turn off the cooler mode and leave only the fan on to dry the cooling pad.

In conclusion, who should consider using an evaporative cooler?

The primary purpose of the evaporative cooler is air cooling. In some work environments where high humidity is prevalent and air conditioners are not allowed to be installed because of the space conditions, an evaporative cooler can be a good alternative. If you wish to reduce electricity bills, you can utilize the evaporative cooler to supplement the air conditioner to improve performance and energy savings. Its affinity to sustainable and environmentally friendly initiatives is also fundamental; as it does not use refrigerant gases, the device reduces CO2 and contributes to protecting the environment.
