What is Industrial Air Cooler in Malaysia?

In Malaysia, the weather is consistently hot all year round. This makes having an air conditioner essential in almost every building, whether it’s for industrial or residential use. However, traditional air conditioners can lead to high monthly electricity bills, and this has led to a shift in recent years.

Over the past few years, Evaporative Air Coolers have become the preferred choice for business owners in Malaysia. Nowadays, you can find at least one factory in every industrial area equipped with an evaporative air cooler.

Given this rapidly growing trend, it’s safe to say that it’s a fantastic option for ventilation and cooling in your premises. But before you decide to purchase or install one, there are five crucial things you should know to get the most out of it. Otherwise, you might end up wasting your money, and the performance might fall short of your expectations.

Question 1: Can I adjust the temperature of the Air Cooler?

No, you cannot. The Air Cooler relies solely on water for cooling and does not use a compressor or “gas.” The air’s temperature when discharged depends on the ambient humidity and the quality of the cooling pad. In Malaysia’s climate, the average air discharge temperature ranges from 23°C to 29°C.

Question 2: Is it necessary to add ice cubes to the Air Cooler?

Yes and no. Adding ice cubes to a portable evaporative air cooler has a similar effect to placing ice cubes in front of a fan. The ice cubes absorb heat from the surrounding air, lowering the air’s temperature. 

However, this cooling effect is temporary and lasts only until the ice melts into water. In other words, it serves as a “temporary booster” for cooling when you need immediate chilling from the air cooler. While having ice cubes is a bonus, the air cooler still performs well without them. The choice is yours.

Question 3: Does a higher HP (horsepower) produce more cooling capacity?

No, it does not. HP typically refers to the power of an air conditioner compressor. However, for an air cooler, the primary consideration is airflow when choosing the size, which ranges from 5500CMH (Portable) to 40000CMH (Fixed Type).

Question 4: Will the cool air “escape” to the outside of the building?

No, it will not. Fixed Type Evaporative Air Coolers for buildings work best with external air circulation, allowing them to continuously replace indoor hot air with cool air. This means there’s no need for a closed space.

Question 5: Does an Air Cooler require scheduled maintenance services?

A Fixed Type Evaporative Air Cooler without maintenance service for 1 year.

 Yes, it does.

The recommended interval for maintenance services is every 6 months for commercial areas and every 3 months for industrial areas. This ensures the highest efficiency, cleanliness, and hygienic conditions.

Question 6: Is an Air Cooler Similar to an Air Conditioner (Air-Con)?

While they both release cool air into a room, air coolers and air conditioners are actually quite distinct! Air conditioners use refrigerant gas to rapidly cool the air, akin to how a refrigerator operates, resulting in an icy blast of air. However, the machinery required for this process is bulky, heavy, and costly!

Air coolers, on the other hand, employ a natural method known as evaporative cooling to cool the air. Consequently, they do not rely on intricate machinery, making them more affordable, compact, lightweight, and portable. 

Moreover, they consume significantly less electricity, making them eco-friendly and cost-effective. Although they may not match the cooling capacity of an air conditioner, air coolers typically provide ample cooling for most homes and offices!

Question 7: Where are Industrial Portable Air Coolers Most Effectively Used?

Portable air coolers are most effectively used in environments where traditional air conditioning is impractical or too costly. This includes large open spaces like warehouses, factories, workshops, and garages. They are also ideal for outdoor events or in locations where temporary cooling solutions are needed. 

Their portability allows for easy movement to target specific areas that require cooling. Additionally, these coolers are beneficial in regions with dry climates, as they add moisture to the air while cooling, improving overall air quality.

The Ultimate Question: Can a Fixed Type Air Cooler be used in a fully enclosed building?

Yes, it can.

In theory, it can be installed in any type of building, whether enclosed or open. However, using it in an enclosed building can lead to increased moisture levels, potentially causing humidity-related issues like mold and mildew growth, which can damage property in the long run.

But there’s a solution. To prevent moisture buildup inside an enclosed building, the Fixed Type Evaporative Air Cooler always comes with an Exhaust Fan. This combination allows precise control of the airflow going in and out of the building. It can create either positive or negative pressure inside the building, depending on the specific requirements.

For example, a factory may need positive pressure to minimize dust and airborne contaminants from entering. Achieving this involves allowing more air to enter through the air cooler than exit through the exhaust fan. Conversely, a factory with heat-generating machinery may require negative pressure to quickly remove heat, which involves allowing more air to exit through the exhaust fan.

Advantages of Air Cooler:

  • Environmentally Friendly: Water is the only cooling medium, making it safe for the environment.
  • Fresh Air Supply: Continuous outside air supply helps maintain healthier indoor air quality.
  • Cost-Effective: For an average-sized building of approximately 1200 sqft, a 23000CMH airflow with a 15kW motor costs less than RM0.80/hour (commercial and industrial tariff) for electricity.
  • Fully Customized Design: The most common ductwork designs paired with Fixed Type Evaporative Air Cooler are Spot Cooling and Direct Blow. Spot Cooling is suitable for cooling a specific area within a large space, while Direct Blow is ideal for small and medium-sized buildings.

The Main Component: Cooling Pad

Cooling Pad: The main component that affect cooling effect of air cooler. 

The key component of an air cooler is the evaporative heat exchanger, specifically the 5090 type “multi-layer” corrugated fiber composite wet curtain. This component is essential for its excellent water absorption and ventilation properties, directly influencing the cooling effect.

The corrugated design creates a large surface area between water and air, facilitating rapid evaporation. However, because the cooling pad remains wet, it will eventually wear out and require replacement, typically every 2 to 5 years, depending on usage.

Some cheaper alternatives offer “long-lasting” cooling pads made from recycled materials, claiming a lifespan of up to 10 years. However, they often compromise water absorption efficiency, resulting in minimal cooling effects during operation.
