Industrial air coolers are a great need in high mild zones where heat and humidity make working conditions unbearable. The need is more noteworthy in production units like manufacturing plants, distribution centers, thermal plants. A hot and humid environment will lead to low production performance of an employee. An air cooler like desert coolers won’t just cool a working environment yet, in addition, emit new clean air to its surrounding. An Industrial cooler does give comfort as well as is decent business speculation for improving productivity.
Most modern air coolers like desert coolers depend on innovation that has been studied the climate of humid and hot areas to guarantee maximum performance. Depending on the Evaporative techniques, industrial coolers can likewise be named as evaporative coolers.
There are even substantial large cooling units that highlight large water tower frameworks that help the cooling limit of the cooler.
Nowadays, Innovation has introduced the eco benevolent coolers that transmit fewer Chlorofluorocarbons into the atmosphere. The outcome is low carbon discharge, water, and energy preservation highlights. It makes well for a business to introduce a cooler as opposed to a focal cooling unit predominantly as a result of low power utilization and additionally enhanced cooling which gives cleaner decongested air because of its dehumidifier working in the cooler.
An industrial cooler will highlight an extensive water tank to store water. For better water protection, an eco well-disposed air cooler will have a bigger capacity limit and use water assets to the greatest without wastage. The cooler will retain warmed air into its framework which is gone through the water and cooling media. It is an area where the actual cooling framework happens where heat and dampness are absorbed and evaporated. The subsequent cool air is extinguished of the framework with the assistance of ground-breaking engine driven fans. The channeling framework conveys chilly dampness, water, and air all through the cooler. Cooled air discharged from a swamp type cooler has the ability to decrease temperatures somewhere near 30 degrees. The quick cooling framework works superior to anything a cooled which takes for a spell till the air is cooled. The innovation in modern coolers and desert coolers depends on such dissipating frameworks to give better outcomes. Also, the cooling region of an air cooler is more extensive than that of an AC. Modern coolers use cooling media innovation which includes a cooling cushion comprising of water blended with a coolant.

★ Compact and very portable
How much water is required for an Industrial Cooler?
The amount of water cooler uses depends on three factors:
Size of the Unit:
The smaller unit will consume less water. For instance, A system that is below 100 watts or 500 CFM requires less than 4 liters per hour. The bigger unit may require 20 gallons.
Combination of Humidity and Heat:
Generally, on a dry day, the system will require more water to give an increased cooling solution.
The drain valves:
A drain valve will facilitate recycle water to be drained out, and freshwater is used. The recycled water is drained from the cooler because it prevents the mineral deposits accumulation which causes damage and corrosion. The continuous drain will result in 50% more water use whereas when it rained intermittently, additional water can be decreased to 10%.
The evaporative air cooler is a type of air conditioner that works by harnessing the power of evaporation to cool air temperatures. When water evaporates, it turns from liquid to gas. The highest-energy particles leave the water first, and this leads to a drop in temperature.
Evapoler’s Evaporative coolers are very effective, economical and use an environmentally friendly method of cooling. However, that there are limitations as to the appropriate uses for Evaporative Coolers. For instance, evaporative coolers must not be used in a closed and unventilated area because coolers depend on a flow of fresh air to enable the process to work. If coolers are used in an unventilated area they will simply pump humidity into that area making it very damp and this could be harming to electrical systems in that area.
This Evaporative Air Conditioning is suitable for areas with adequate natural ventilation and not sealed spaces. Whilst there are many Evaporative Coolers in use, the users are not really familiar with the real principles of how evaporative cooling works.
To provide you an instance of the principle used in evaporative cooling simply try the following experiment. On a hot summer day place your arm in a bucket of warm water and then remove it. You feel a slight chill over the wet area. This has been happened by the evaporation of the water off your arm, the very action of evaporation is the energy for the cooling. Evaporative cooling is more powerful and suitable for many applications, inexpensive both to purchase and to run and it is more effective in drier climates and can be used for everything from residential homes to large buildings such as warehouses and shops etc.
The principle used in Evaporative Cooler
Generally, water is evaporated, energy is lost from the air, reducing the temperature. Two basic temperatures are important when dealing with evaporative cooling systems.
Dry Bulb Temperature
Dry bulb temperature that we usually think of as air temperature, measured by a regular thermometer exposed to the air stream.
Wet Bulb Temperature
This Wet Bulb Temperature is the lowest temperature that can be reached by the evaporation of water only. When water evaporating into the air, the wet-bulb temperature, as compared to the air’s dry-bulb temperature, is a measure of the potential for evaporative cooling. Both bulb temperature can be used to calculate the relative humidity.
During Evaporation take place when the humidity is below 100% and the air begins to absorb water. Any specified volume of air can hold a certain amount of water vapour and the degree of absorption will depend on the amount it is already holding.
The word humidity describes how much water is already in the air; relative to the amount it is capable of holding.when the Air is saturated when it cannot hold any more water. assume, it like a sponge, if the sponge hold half as much water as it was capable of holding, it could be 50% saturated. In the case of air, we could describe the Relative Humidity as being 50%.
The Energy is needed to change water from liquid to vapour. This energy is obtained in a natural process from the air itself. The Air is entering an evaporative air cooler gives up heat energy to evaporate water. while this process, the dry bulb temperature of the air passing through the cooler is lowered.
An Evaporative cooling is a phenomenon in which evaporation of a fluid is circulated into surrounding air. This evaporation of the liquid is occurred by retaining latent heat from the air. To discover the estimation of water evaporated into the air, the Dry Bulb and Wet Bulb temperature are expected to quantify for deciding the extent for evaporative cooling.
Evaporative cooling utilizes less power almost one-seventh of the customary utilization strategy, it is essential that our environment would add to the greenhouse gas emission and control.
Evaporative cooler unit includes a cubical box of sheet metal containing huge vertical channel pads, an electric-engine driven fan, a water distribution framework, a water pump which is at the base. Coconut coir, Stainless steel, Wood Wool utilized as Pad materials.
The performance analysis of evaporative cooler was assessed dependent on the terms of cooling effectiveness, water utilization rate, and air velocity.
Here are three basic pad materials and their prominent attributes:
Wood-The most widely recognized wood fiber pad is produced using shaved aspen trees. Some bog cooler proprietors say they like cushions built with aspen strands since it strikes the best air and water balance. It enables more air to travel through increasingly a somewhat immersed cushion, which produces cooler air inside the house. The wood absorbs just one part of the water, which doesn’t deliver over-saturation that can prompt the water being held in the pad and warming up. They are less expensive, require high support and have a shorter life.
Cellulose-These pads are made with a cellulose paper molded with a honeycomb construction. It holds more water because of the thick material. This might be perfect in dry conditions where the water could evaporate all the more rapidly or in a circumstance where your cooler has a solid fan that produces more prominent air speed through the pad bringing about lower temperatures. Cellulose pads are more costly than wood.
Plastic-Plastic-based pads are not effective when compared to other pad types. They are not absorbent in nature; plastic in general repulse water instead of absorbing it! They are likewise thin and cost-effective. The plastic pads can be used for a shorter term.
Role of Cooling Pads in an Evaporative Cooler
- The cooling pads are the main component of an evaporative cooler because the cooling pads are in charge of the cooling effect.
- The cooling pads in an evaporative cooler enable water to go through them.
- The water circulates through the pad will carried out with the help of pump.
- At the point when the water goes through the pad, a fan blows over it, discharging the water infused air into the air.
- The tiny water droplets which are evaporated from the air will cool the environment.
Since the majority of the work is done by the cooling pads, the electrical consumption of an evaporative cooler is low.
Here are some tips on how to choose an evaporative air cooler. You wouldn’t be browsing in here if you were not complaining of the hot climate you are enduring at the moment. The low humidity and warm air has probably taken its toll on you to push you to find the most suitable evaporative air cooler for your home or office. Buying stuff can be particularly hard for you if you really want something worth your money, well, that is just how smart shoppers are. There are so many brands and units flooding the market and anyone in their right mind would also be swamped too. At the end of the day, you will be asking yourself, “Which cooler should I choose?”
So to aid you in selecting the right brand and right unit of evaporative air cooler here are 17 helpful tips you need to know:
Note the area you need to be cooled and the unit’s CFM rating
Before buying an evaporative cooler, you should take into account the size of the area you need to be cooled or the number of rooms you need to be cooled since coolers have varying capacities in cooling spaces. A bigger space may require a bigger unit for cooling and in the same manner; a smaller unit may be ample for a smaller space. The goal is to supply the consumers with the ideal evaporative air cooler that will work efficiently to maintain cooling without wasting energy.
To find the best evaporative cooler that will be appropriate for your needs then calculating the CFM rate should be done. The CFM aka as the cubic feet per minute is the amount of air that circulates in a space or environment per minute. To determine the CFM rating to find the evaporative air cooler that will efficiently cool your space, simply multiply the square footage of the space or room by the ceiling’s height in feet and divide it by two. The result of the equation is the CFM.
350 square feet x 10 feet= 3500 Cubic feet/ 2= 1750 CFM
Note the cooler type
Evaporative air coolers come in many types and these are:
- Portable coolers usually are ideal in cooling small rooms of up to 300 square feet
- Window or through-the-wall coolers can cool an entire room or the whole house or garage
- Down discharge coolers are placed on the roof, releasing the cooled air descending into the edifice and are intended to cool the whole home.
- Slide discharge coolers are usually placed in the side of the building but can also be placed in the roof, using an elbow to run the wind current through an opening in the top. It can cool the whole house.
- Mobile coolers are more adept to be used in larger spaces such as garages or warehouses and even outdoors like in patios.
Note the evaporative pad type
Evaporative pads are the main cores of the cooling system. They can either be fiber or rigid media pads. Fiber pad are economical than rigid media however require more cleaning and maintenance and even replacement. The rigid media, in contrast, is more costly but require less cleaning and maintenance but can last a considerable length of time if properly taken care of.
Check the fan types
Evaporative air coolers can either be equipped with a centrifugal fan or an axial fan. The centrifugal fan is drum-shaped and is generally quieter but consumes more energy for cooling and costs more than the axial fan. The axial fan, on the other hand, is cheaper, uses less energy but is much noisier.
Check the material of construction
The most important thing to consider is the ability of the material to resist corrosion. The materials that fit this criterion are plastic (polyethylene or polypropylene made units), marine grade aluminum and stainless steel.
Check if it has a remote control
A majority of the evaporative air coolers currently available are equipped with a remote. At least with remotes you will be able to set your evaporative air coolers even across the room.
Check if it has air throw up for outdoor use
For outdoor use you will need to procure an evaporative air cooler that has a wide air throw-up.
Check for adjustable louvers
Most of the evaporative coolers now are equipped with adjustable louvers that are able to redirect stream of air from the unit into any one direction, usually just up and down. But if you choose to go a step higher there is also the oscillating type that allows air to be redirected in varying directions.
