Industrial Evaporative Cooler

Industrial evaporative coolers are mainly used in large spaces such as factories, warehouses, halls, shopping malls, and mosques. They have a lower initial cost for setup and installation compared to other industrial air conditioning systems, which makes them a popular choice. These coolers are most effective in hot and dry (non-humid) climates.

Professional Guide for Selecting and Pricing Industrial Evaporative Coolers

Industrial swamp coolers look very similar to standard evaporative coolers, as both rely on water evaporation to provide cooling. The main difference lies in their size and power.
Moreover, industrial evaporative coolers require lower initial installation costs compared to other types of central industrial HVAC and refrigeration systems.
In general, the industrial evaporative cooler is an important and widely used cooling solution to balance the temperature in halls, warehouses, greenhouses, poultry farms, mushroom farms, and workshops, preventing excessive heat and potential damage.
Due to the larger size and higher volume of industrial spaces, heat rises more quickly than in residential areas, which is why stronger cooling units are required.
Industrial Evaporative Coolers are highly suitable for industrial environments located in hot and dry climates.
Since industrial environments often produce dust, paint particles, and other airborne pollutants, industrial swamp coolers not only provide cooling but also help ventilate and refresh the air.
For this reason, the industrial evaporative cooler can also be called an evaporative air cooler. Built with advanced cellulose pads, it delivers excellent performance.

Types of Industrial Evaporative Coolers

When choosing and purchasing an industrial evaporative cooler, it is important to consider factors such as features, advantages, technical specifications, how the system works, capacity, brand, price, and warranty. Generally, industrial evaporative coolers come in different types, giving users the ability to choose the right model based on their production or industrial facility needs.
They are mainly divided into two categories: pad coolers and cellulose pad coolers. According to their fan system, they are further classified into axial fans (for direct air blowing without ducts) and centrifugal fans (for ducted air distribution).
Industrial evaporative coolers are produced in different capacities and are used for cooling workshops, factories, large halls, warehouses, industrial sheds, recreational facilities, exhibition centers, garages, swimming pools, and other large spaces.

How an Industrial Evaporative Cooler Works

Just like regular evaporative coolers, the industrial type uses water evaporation to cool the air. It draws in surrounding air, passes it through evaporating water, reduces its temperature, and finally distributes the cooled air into the desired space.
Industrial swamp coolers can be used in sports halls, shopping centers, large and small industrial spaces, factories, production centers, offices, cultural and educational facilities, workshops, laboratories, healthcare centers, hospitals, mosques, large public halls, poultry farms, cattle farms, large residential buildings, and many other similar areas.
Some polymer industrial evaporative coolers, considered part of the cellulose category, are suitable for both industrial and large residential applications.

Main Components of an Industrial Evaporative Cooler

Industrial evaporative coolers are made of several key components, including:

Industrial Evaporative Cooler's Case

The body protects internal parts and is cube-shaped, similar to standard units, but much larger in size. It is designed for durability against environmental factors and also reduces noise levels.

Industrial Evaporative Cooler's Fan

Industrial evaporative coolers come with either centrifugal or axial fans. Centrifugal fans use centrifugal force to push cooled air into duct systems, while axial fans blow air directly into the space without ducts.
The main difference between centrifugal and axial fans lies in their design and performance. Centrifugal fans are spiral-shaped, turning the cooled air by 90° before distributing it into ducts, while axial fans are propeller-shaped and deliver large volumes of air directly to the environment.
Axial fans move large amounts of cooled air directly into the space but are not suitable for ducted distribution.

 Cooling Pads of Industrial Evaporative Cooler

The efficiency of an industrial evaporative cooler also depends on the type of pads used. Modern cellulose pads have higher cooling efficiency, absorb water better, and last longer compared to traditional pads.
Other essential components include the motor, belt, bearings, water distribution channels, overflow pipe, and float valve.

Factors to Consider When Choosing an Industrial Evaporative Cooler

Selecting the right type and capacity of an industrial evaporative cooler—typically used for workshops, warehouses, industrial halls, gyms, exhibitions, and production spaces—requires careful consideration of several important factors to ensure effective performance.
According to HVAC experts at DamaTajhiz, the main criteria include:

• Accurate dimensions of the hall (length, width, height)
• Climatic conditions (in summer, the relative humidity should be below 40%) in cities like Karaj, Semnan, Arak, Tehran, Tabriz, Kerman, Yazd, Shiraz, Isfahan, Baku, Yerevan, Sulaymaniyah, Kermanshah, Hamedan, Qazvin, Erbil, Kirkuk, Mashhad, Kabul, Mazar-i-Sharif, etc.
• Type of usage and the number of occupants
• Airflow volume and capacity of the cooler
• Motor power and static pressure of the centrifugal fan
• Material, thickness, and dimensions of the cooler body

Considering the Humidity of Your Area in Summer

Industrial evaporative coolers work based on water evaporation to cool the air. During summer, they depend on the evaporation of water through cellulose pads or wood-wool pads to provide ventilation and cooling.
Therefore, if you are in a humid region where the summer humidity is usually above 40%, it is better to also consider alternative cooling options. Using an industrial swamp cooler in high-humidity areas can significantly increase indoor moisture levels, causing the air to feel heavy and uncomfortable.

Airflow Volume (CFM) of Industrial Evaporative Coolers

The airflow volume of industrial evaporative coolers is very important. In fact, these coolers are chosen because of their ability to handle large halls with high cooling capacity and strong air circulation.
One of the main factors that boosts the airflow and cooling performance is using a more powerful motor and a centrifugal fan with sufficient static pressure to push air efficiently through ducts and outlets.

Dimensions, Material, and Thickness

The metal sheets used for the body and base of industrial evaporative coolers must be thick, durable, and high quality.
One of the key points when selecting an industrial evaporative cooler is the thickness and coating of its body. The thicker and more durable the body and base (with proper electrostatic painting), the higher the quality and longevity of the cooler.

Cellulose Cooling Pads

The cellulose pads in industrial swamp coolers, which cool the incoming air, must be of the right size, thickness, and quality.
When the centrifugal fan operates, fresh cooled air passes quickly through the moist cellulose pads into the environment.
If the pads are low quality or contaminated, they will reduce air quality, cause malfunction, and increase maintenance costs due to frequent replacements.

Motor Power and Static Pressure of the Fan

When choosing an industrial evaporative cooler, you must pay attention to the motor power and required airflow capacity (CFM) based on the size of your hall, workshop, warehouse, or factory.
The required airflow for cooling each environment can be calculated using engineering methods by DamaTajhiz experts.
Additionally, to allow air to flow properly through ducts, you should consider the motor’s static pressure capacity.

Application of Industrial Evaporative Coolers with Centrifugal Fans

Coolers equipped with centrifugal fans generate strong static pressure for cooling industrial and production environments, and can be installed on rooftops, balconies, or terraces.
The outlet of these coolers can be positioned either at the bottom or on the side wall, depending on the installation location.
Industrial evaporative coolers with centrifugal fans are widely used in industrial settings, providing cooling, ventilation, and fresh air circulation.
The cellulose pads not only cool incoming air but also act as air filters, improving indoor air quality.

Application of Industrial Evaporative Coolers with Axial Fans

This type is a newer generation of industrial evaporative coolers, designed for window or wall installation in workspaces and production halls.
Industrial swamp coolers with axial fans (propeller type) deliver large volumes of cool air directly into the space without ducts. However, axial fans cannot generate static pressure for ducted airflow.
Advantages of axial fan industrial coolers include energy efficiency and the use of high-quality cellulose pads.
They do not require ductwork and are manufactured in three outlet designs: top discharge, bottom discharge, and side discharge.
The dampers in axial industrial coolers are of two types:

• Automatic Damper:
  Operates with the airflow from the fan and closes when the fan stops. The disadvantage is that it always creates resistance against the airflow.
• Clutch Damper:
  Uses centrifugal force transferred to a plastic clutch to open the damper. When the fan stops, the damper closes. The advantage is no resistance to airflow, but the downside is possible clutch breakage.

Advantages of Industrial Evaporative Coolers

Main benefits include:

• Maintains suitable humidity levels
• Consumes much less electricity compared to air conditioners
• Provides uniform cooling across large spaces

- They use a water pump to circulate water over cellulose pads.

- Iranian-made industrial swamp coolers are built with high-quality parts according to international standards.

- Their bodies are made of durable galvanized steel with electrostatic paint, providing resistance against rust, corrosion, wear, and sunlight.

- When installed outdoors, the cooler body withstands wind, rain, and dust.
