Industrial Evaporative Coolers Guide for You

In some places in industries, a lower temperature (compared to atmospheric) is required from a process point of view or from a comfort point of view. Air conditioning is out of the question, as it would require large capital and huge running payment of electricity bills. Evaporative cooling is the solution in this case. This is just a scaled up model of home air coolers.

Working Principle Of Evaporative Coolers

Evaporative cooling is known to humanity since ages. Earthen clay pots have been providing cold water during summer when there was no air conditioning or refrigeration. The fired clay pots have tiny holes through which water comes out and when it comes to the surface, it evaporates.

The heat required for evaporation is taken out from the water inside the pot. The heat transfer from the water is possible only because of the tiny passage in earthenware pots. The same principle is used in industrial evaporative coolers.

Air circulating fans draw air through a curtain of water. The water trickles down a path and during passage; water is broken down to tiny droplets giving it a large surface area. Air is drawn through these tiny droplets and is cooled the same way as it happens in an earthen pot.

The cold is circulated through the industrial installation. This gives installation an air which has a lower than atmospheric temperature. Evaporative cooling gives you a comfortable atmosphere when outside is too hot to bear. Here is a review of Industrial Evaporative Coolers that you might need it.

Advantages Of Evaporative Cooling

An advantage of evaporative cooling is the initial low cost and low operating costs. All that is required is the water pumps and the air circulating fans. The whole set up is compact. Evaporative cooling is the only method of removing a large quantity of heat from cooling water used in many industrial plants. Here instead of removing heat from the atmospheric air, heat from the water is rejected to atmospheric air.

How much water does an industrial air cooler use?

The amount of water your cooler uses depends on three primary factors:

  • Size of the unit:

Generally, the smaller the unit, the less water it will consume. For instance, a system that is under 100 watts or 500 CFM averages less than 4 liters per hour. On the other hand, a bigger unit may use as much as 20 gallons.

  • The combination of heat and humidity:

On a dry day, the system will use more water and provide added cooling when compared to a humid day.

  • How the drain valves are used:

A drain valve allows recycled water to be drained out, and in its place, fresh water is used. Draining the recycled water from the cooler is essential as it prevents the accumulation of mineral deposits in the water that tends to cause damage and corrosion. However, you should know that a continuous drain may result in 50% more water use. When drained intermittently, additional water use can be reduced to about 10%.

Main Things to Consider When Buying a 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.Air cooler comes with a variety of features but here are some of the important ones that can be of great benefit to you.

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

  • Case material & thickness

Fresh material or recycled material? If used fresh material, it could be used for 10 years, while if using recycled material might have some problem after 1-2 years. The case material used should be fresh and not from recycled materials in order to guarantee long life. It should also be of the right thickness. Generally the thicker, the better.

  • Cooling Pad

For an industrial cooler to function effectively, it needs to have the right cooling pad based on size and thickness. The thicker and bigger the cooling pad, the better the cooling performance.

  •  Fan for Motor wiring

100% copper wiring is best suited for a cooler in order to be effective and work well. Some manufacturers use aluminum motor wiring to be cost-effective but will end up compromising the quality of the product.

  • Checking  airflow volume

Thoroughly check the airflow volume because some suppliers indicate a higher value than what is in the specification sheet. This may be misguiding and you will end up with an industrial cooler that doesn’t meet your specifications.

To ensure you are not dubbed into buying a cooler that is short of your specifications, calculate yourself the air flow volume. By doing these you will be certain you have the right product.
