Industrial fans are more economical. In this type of fan, the power of the alternator is transmitted to the impeller through a belt. In addition to the above, the structure and operation of these fans are such that they reduce polluting particles. Using this type of fan in coolers provides energy efficiency, adaptability to various types of air flow and pressure; greater durability and ease of maintenance, which makes it more ideal for industrial environments.
3-2. Axial fan
This type of fan can cool the environment by blowing and transferring the cooled air in the cooler chamber to the duct outlet. In this type of fan, axial force is used to transfer cool air. In some types of this fan, the connection between the electric motor and the fan is established directly, so in this type, mechanical losses caused by the belt connections are minimized and the power of the alternator is transferred to the impeller through a direct cable. Some types of this type of fan are suitable for industrial workshops without ducting and are produced in two types: fixed and portable. Coolers with this type of fan take up less space in the environment and are also suitable for high air flow rates. On the other hand, due to the way the impellers are placed, access to the motor is more difficult and it is not suitable for high flow pressures.
The choice of which type of technology is more suitable depends on the application and environment in which the cooler is located, such that coolers with axial fans are suitable for transferring air from one area to another due to the low-pressure, high-volume flow, while centrifugal systems are suitable for applications such as cooling or drying due to the high-pressure flow and are more ideal for industrial environments that contain polluting particles than the axial type. With the same fan speed, most coolers with axial fans are less efficient than coolers with centrifugal fans.
4. Electric motor
The electric motor uses a pulley belt or direct drive to move the fan inside the cooler. The electricity and motor of evaporative coolers can be selected as single-phase or three-phase, of course, three-phase electricity is ideal for large and industrial places. In addition, the nominal power of the system is also important in the efficiency of the cooler. When buying a cooler, you should pay attention to its nominal power, which is in horsepower. Some industrial coolers are equipped with an intelligent ambient temperature control system that adjusts the motor speed according to the temperature. Also, by installing an inverter, several different speeds can be added to the cooler so that the speed of the cooler’s motor can be manually reduced when necessary.
5. Water pump
The water pump is responsible for supplying water from the bottom compartment of the cooler (pan) to all surfaces of the cooling pads, whether cellulose pads or straws, and is generally responsible for supplying water. The number of these pumps in industrial coolers varies and can be 2 or 3. Using standard pumps saves electricity. In addition, the ease of installation, repair and maintenance of these systems is also significant. Each water pump has a power characteristic in watts and engine speed in revolutions per minute.
6. Why choose an industrial cellulose cooler?
There are several options for cooling industrial environments. Evaporative cooling systems (such as industrial coolers), gas coolers, ducted splits, chillers, and central splits are among the systems that can be used to create optimal cooling in the environment. In comparing and economically selecting a cooling system, the total purchase cost and installation cost of the equipment should be considered, in addition to operating costs including service and maintenance costs and energy consumption. Now the question arises: why choose an industrial cellulose cooler?
- Lower initial cost compared to other cooling systems
Cellulose industrial coolers have a very reasonable purchase cost compared to other cooling systems.
- Lower electricity consumption
The major weakness of refrigeration systems is their high electricity consumption. The average cost per ton of refrigeration is $2,000. In cellulose industrial coolers, energy consumption is very low and efficiency is high. Cellulose coolers increase efficiency by nearly 90 percent thanks to unique components and special design. Cellulose pads hold a large volume of water and, in addition to increasing efficiency, have a high cooling speed. Paper pads hold less water and are about 85% efficient.
- Uncomplicated installation and maintenance
Gas air conditioners, ducted splits, chillers, and central splits are all complicated to install and maintain, and in the event of a device failure or service, specialists are needed.
