Industrial air cooler provide an effective amazing cooling effect in almost anywhere. Industrial air coolers are also referred to as industrial swamp cooler or industrial evaporative cooler. They are used to provide large-scale powerful cooling in factories, huge indoor spaces and outdoor areas. Such systems are also used as a cost-efficient cooling solution in dry climate regions.

Industrial coolers function by evaporating water to lower heat and moisturize the air in a process similar to natural processes. They are more eco-friendly and efficient in energy consumption than traditional air conditioners. Typically, they are also more powerful than normal outdoor fans. Among the key places they are used to cool include warehouses, manufacturing plants, workshops, construction sites and hangars. Others are gyms, loading docks, large tents, garages, farms, athletic events, barns, pool or patio areas, etc.

Types of Industrial Air Cooler

1) Portable Evaporative Coolers

Also known as portable air coolers, One kind of  industrial evaporative air coolers. these are most applicable in commercial areas like warehouses and garages. They can also be used other outdoor areas like patios. Typical sizes go up to 13,000m3/h.

Advantages of Mobile Evaporative Coolers

  • Quite cost-effective
  • No installation required
  • Compact and very portable

Disadvantages of  Mobile Evaporative Coolers

  • Require good natural ventilation to operate optimally
  • Depends on ambient humidity to perform optimally

2) External Evaporative Coolers

These are built mostly for huge commercial or industrial settings and operate by displacing warm air to the outside.  Industrial air coolers include window or wall-mounted air cooler, slide discharge cooler  and down discharge cooler . Typically, their cool air supply goes up to 30,000m3/h per unit.

Pros of External Evaporative Coolers

  • Cost-effective operation
  • Covers larger areas than portable mobile coolers
  • Cools outside air, which already has lower temperatures than indoor air

Comparison: External vs Mobile Evaporative Coolers

  • Externals are more efficient in their cooling
  • External units are less noisy than mobiles because their fans are outside
  • Cooler for External have a perminent connection to the water supply
  • External Evaporative Cooler operation is less intrusive (out-of-sight, out-of-mind cooling)

3) Three Ways to mount extend coolers

The range of an external cooler is determined by air direction, i.e. how the cooling machine faces the air outlet.

(i) Window or wall-mounted evaporative coolers are capable of cooling a whole room/house or an entire garage area.

(ii) Down-discharge air coolers are located on the roof and release cooled air downwards. Their air outlets descend directly into the target building and can be used to cool entire homes.

(iii) Slide-discharge air coolers are normally placed on the side of a building, but also on the roof. They use an elbow to beat the wind into a current through an opening on the top and can cool entire houses.

 How Evaporative Cooling Work?

Air cooler portable working

Evaporative cooling literally means cooling using water. Remember that cooling sensation you feel on your skin as you leave a swimming pool? That is natural evaporative cooling at work. Similarly, that is how we feel the cool breeze that blows across a lake’s surface. By water being evaporated, the temperature of the air particles in contact with liquid water below reduces. This is due to an endothermic reaction that occurs. This reaction converts liquid water into a gas, thus lowering the temperature of adjacent air molecules.
An evaporative cooling machine operates using this principle. It acts as a cooling fan that utilizes three key things: water, a wetted surface and a pump. The pump pulls air particles across the water, lowering their temperature. The pump is operated by a mechanical control system located within the cooler machine. The rotating fan then distributes the cooled air to the intended space.

How Effective is Evaportive Cooling?

Absolutely, and it can be applied almost in any place on the planet. However, for obvious reasons, evaporative cooling is mostly used in dry climates. In fact, these areas are where this cooling system is most efficient. The swamp cooler uses heat from the outdoors air to trigger this evaporative process. What this means is that its efficiency will also be affected by factors like overall humidity and temperature levels. The chart below illustrates ambient temperatures, humidity levels, and the temperatures delivered by an evaporative air cooler in optimal conditions:

How to Calculate the Size of Industrial Swamp Coolers?

An industrial air cooler‘s cooling power is based on how much air flow it can generate. It is for this reason that these coolers are categorized by air flow. They are typically rated in cube meters per hour (CMH), cubic meters per minute (CMM) or cubic feet per minute (CFM). This calibration measures the total amount of air an air cooler can pump or move per unit time.

The size of the space you’re targeting with a cooling system is what determines your choice of machine. Typically, you’ll need a machine calibration of roughly half the air flow area in your target space. This is a good approximation for an enclosed space like a warehouse, garage, patio, or outdoor shed or tent.

Generally, the less enclosed your target area is, the more powerful a cooler you’ll need. Air flows in more open spaces are more difficult to estimate. However, you can use the above formula as your basis point. For instance,

If you’re organizing a function in a tent of 10 x 10 x 5 = 500m3

Air exchange per hour = 20 times

Total amount of air replaced per hour = 500m3 x 20 times = 10,000m3

You will buy a cooler unit with a 10,000 CMH rating.

How to Choose the Best Industrial Air Coolers

Industrial plants require various kinds of maintenance systems. These are required to keep the operation and performance of their machines and equipment at optimum. Among these key appliances and systems is a proper and efficient industrial air cooler. It’s used to make sure an industry’s overall environment remains safe and well-maintained at all times.

So, what factors should you consider as you look for the best industrial cooling system?

1) Brand and Model:

Different makers and brands of  industrial air coolers exist. You can start by exploring the websites of the various manufacturers available to know what kind of industrial air cooler they make. Check them vis-a-vis your own cooling needs and specific industrial thermal conditions, and then decide.

2) Seller’s Reputation:

You can get this mostly from online reviews and feedback from previous buyers and users of their product. Go for brands with highly-positive feedbacks from customers. It shows their  industrial air coolers are of superior quality. Also, make sure the reviews you’re depending on are authentic. You can randomly contact a number of the reviewers to hear from them directly.

3) Budget:

Your budget is another important factor. Different brands come with varying rates. Your best bet would be to go for a brand that is moderate in their rates but are also highly reputable. Don’t sacrifice quality and reputation because of cost.

4) Installation Mechanism:

This is also very important. Some companies do even offer installation as an extra service for their customers. Else, contract professionals, either from the seller or elsewhere, to do this for you.
