It is quite common to see various types of fans in industrial facilities. They are used to regularize the airflow to various structures or parts of the building. There are several types of industrial fans, which are categorized based on their designs, applications, and so on. Industrial cooling fans and industrial cooling blowers are two types of industrial fans used across the industrial facility for cooling purposes. Do you want to know how these fans differ from other types?
This post gives an overview of industrial cooling fans, their beneficiary features, and industrial applications.
What are Industrial Cooling Fans?
Industrial cooling fans are the mechanical devices that create fluid flow for industrial purposes. The industrial cooling fans often considered as fluid displacers since the air or gas is displaced from one point to another due to the rotational motion of blades. The primary purpose of the industrial cooling fans is to blow cold air and drive hot air out of the environment. Therefore these industrial fans are also called industrial cooling blowers. However, cold air intake or hot air exhaust depends on the design and construction of the specific fan. Unlike other industrial fans, the industrial cooling fans have large diameters, which help them produce large volumes of air and low pressures, as required in several environments. Regardless of the fan design, the fundamental components of industrial fan remain the same. They are discussed in detail in the next section.
Fundamental Components of an Industrial Cooling Fan Assembly
Industrial cooling fans comprise a motor, a rotor shaft, and the blades or impellers. These are the fundamental components of the assembly. Check out on the function of these fundamental components and other important features in a fan assembly.
Motor:
An electrical motor is the primary input source in an industrial cooling fan assembly. The motor can be AC or DC as per the design and performance requirements. The motor transfers’ electric power to the hub of the rotor shaft as the energy input.
Rotor Shaft:
The rotor shaft is connected to an electric motor with an intermediate hub. The hub transfers electrical energy to the rotor shaft. The shaft rotates on receiving this electrical energy. This all suggests the conversion of electrical energy into mechanical to get the desired output.
Impellers/Blades:
The blades or impellers are the components that cut through the surrounding air to form a fluid drag. The blades are mounted on the rotary shaft at a specific distance. The blades rotate to push or exhaust air drag. These blades can be designed in multiple shapes according to aerodynamic standards.
Fan Casing:
The fan casing is a metal casing that houses the whole assembly. The main purpose of fan casing is to protect the assembly from dust, external damage, as well as the environmental impact such as corrosion, moisture, dust, etc.
Fan Mountings:
The mountings are bearing on which the fans are fixed on. The industrial cooling fan assembly can be mounted by using a ball or sleeve bearings. The bearings are the foundation of the fan assembly therefore, the quality and function are very important.
These components of the industrial fan assembly remain constant irrespective of the types of industrial cooling fans.
What Are The Different Types Of Industrial Cooling Fans?
There are various types of AC and DC Powered Industrial Cooling Fans used today. The following are a few popular ones.
Axial Fans:
Axial fans are also called helicoidal fans. In these fans, the airflow is generated by blades in the direction parallel to the fan axis. AC and DC axial fans can generate high airflow under less pressure.
Centrifugal Fans:
The centrifugal fans are also known as radial fans. In these fans, the fins are arranged in a right angle to the fan axis. Therefore, the flow of air is in the radial direction of the fan axis. These fans can be designed for forwarding or backward motion of the fluid.
Blowers:
Industrial Cooling blowers are similar to industrial fans, except the impeller and energy utilization. The blower consists of impellers instead of blades. These impellers are designed to utilize kinetic energy during motion, to accelerate or decelerate the airflow. The impellers of a blower transfer kinetic energy to the electric motor, which is then utilized to continue the impeller motion only to vary airflow volume. In this case, blower motor offers re-utilization of energy, therefore less power is required for running industrial cooling blowers.
Cross-flow Fans:
In the cross-flow fans, the air flows in a tangential direction to the fan axis. This is why it is also known as tangential fans. They feature a long cylindrical shape with an impeller that spans the entire width of the fan.
Many manufacturers offer the benefit of customizing these industrial cooling fans based on industrial requirements.
What Are The Benefits of Industrial Cooling Fans?
Industrial cooling fans and industrial cooling blowers are used for multiple purposes in the industries. These fans offer many benefits due to advanced features and excellent designs. The following are the common benefits of industrial cooling fans.
- Due to advanced designs and the latest technologies, the industrial fans offer a varying range of output. Variable output at very small input energy is a benefit to industrial applications.
- Industrial fans are available in a compact yet easy to maintain designs. This makes them an ideal choice for areas that are limited by space constraints.
- Industrial cooling fans offer function-specific features, therefore they can be used in hardcore industrial applications. Due to the operation-oriented functions of industrial fans, the energy consumption has reduced while industrial efficiency has raised.
- Industrial cooling fans create a safe working environment. A good cooling fan offers advanced ventilation which helps in the reduction of dust and pollutants from the area.
Applications of Industrial Cooling Fans
Industrial cooling fans are used in multiple industrial applications and the following are the prominent ones among them.
- Industrial cooling fans are used for industrial de-dusting applications. These fans are used in the ventilation system that allows the clean flow of air into the workspace.Centrifugal fans with cyclone cases are considered the primary choice for such applications.
- Industrial cooling fans are used in HVAC systems, as they are susceptible to multiple temperature rise and drop incidences. Therefore, fans are used for temperature control.
- Duct exhausts find important applications of industrial cooling blowers or fans. In this system, the blowers are used to drive away from the hot exhaust gases from an area.
- In the boiler systems, large centrifugal fans are attached to the boiler walls or surroundings to drive away exhaust temperatures.
However, these benefits of industrial cooling fans can only be reaped if quality equipment is installed. This is because the quality of industrial cooling fan systems highly impacts the airflow and cooling in a facility. Thus, you must buy industrial cooling fans from trusted manufacturers like Sofasco. This company has been supplying all types of industrial fans, since 1981, all over the globe such as, ac and dc cross flow fans, axial fans, centrifugal fans, blowers, dust proof fans and more.
