The industrial sector is a world made up of various elements that, when combined, ensure the development of a product. There are many productive fields, from food to mechanics, from metal processing to the processing of materials that make up objects functional for everyday life. However, regardless of the final result, the production chain revolves around tools among which we also find the extraction tower. torrino di estrazioneLet's see what it is and how this component represents a necessary element in certain companies. So, characterization and purpose of what in many cases is much more than a mere extractor.

What is an extraction tower

After making a necessary introduction to the topic, let's first examine the meaning of the term in question: the extraction tower. This term refers to a system used in industries for the low-pressure suction of certain volumes of air. This component is often noticed at first glance but many are unaware that it is defined in this way. To put it simply and less technically, the extraction tower is nothing more than that mushroom-shaped object that is usually connected to flues or more or less complex suction systems. It is placed on the roof of a structure to convey a certain volume of low-pressure air from the inside to the outside. Therefore, as anticipated in the introductory phase, it is a very useful element, especially when talking about chemical companies or those in contact with similar materials. Here, air filtration is fundamental both for preserving the environmental working conditions and for the protection of workers, and not just for the final product. This discussion helps us understand how this industrial component, often ignored, is actually crucial for maintaining certain environmental conditions inside a workplace. Just like its placement, the extraction tower is at the pinnacle of functionality, not just in material installation. It is the extreme point of a production chain that would otherwise be unable to fulfill its task.

Composition of the extraction tower

Having understood what the extraction tower is and particularly the context of its application, let's now shift our focus to its composition. Alvanized steel and glass in back resin are the two main components of the aforementioned object. These materials are used to make the dome and the part immediately below it functional for protection against atmospheric agents. Inside, there is a motor of varying power that drives a fan useful for air suction. This is very quiet during operation, contrary to what one might think. In fact, when thinking of an industry, the immediate thought is often of the noise and chaos from which workers have to isolate themselves using specific acoustic protection devices.

The range of extraction towers

There is a wide range of extraction towers, which you can also find on our websitediffering mainly in the power of the suction motor. There are nine different models of motors, all three-phase, providing significant drawing and subsequent filtering power. Alternatively, there are also single-phase models equipped with variable speed controllers to regulate the air flow. Depending on its characteristics, the extraction tower can operate up to a maximum temperature of 200 degrees. Such delicate operating conditions can only be sustained by materials like steel and zinc. In fact, the extraction tower is a component specifically designed as explained above to operate without any problems under the mentioned conditions.

Other technical features of the extraction tower

Let's now examine other technical features of the extraction tower, in addition to those listed so far. Among these, we find a proportional weight-to-size ratio conducive to proper functioning. This also greatly facilitates its mounting on roofs and tops of structures of interest. Indeed, the lightness of the component in question is aimed not only at its use but also at its insertion and relative installation. This factor also makes the extraction tower an extremely long-lasting element. It can last many years due to the galvanized and steel coating between the inner and outer parts. This aspect also has a positive impact on the economic side, as such exquisite manufacturing does not entail additional maintenance costs.The fan housed inside is perfectly stabilized to ensure there are no oscillations or unexpected movements. The motor powering it, being of great power in the vast majority of models, drives the fan at a high speed. This would affect the correct aspiration process if the aforementioned fan were not balanced. Not to mention the further impact on the quietness of the suction mechanism, always related to stabilization. In short, from what can be gleaned about the characterization and constitution of the tower, we are undoubtedly talking about a tool of artisanal excellence. A component that is made and designed not only for the task it must perform, but also for the protection and safeguarding of its usage conditions. The better the quality of its parts (motor, fan, etc.), the more likely it is to withstand the years. All this without having to resort to corrective and maintenance interventions, which are often not only costly but also invasive and not entirely effective. The extraction tower is therefore a key object in various types of industrial production, as it represents not just a mere air filtration and suction system, but an indispensable means for the protection of a work environment. Especially when the latter involves materials or chemical compounds, often releasing residues and fumes that absolutely need to be evacuated.

Active control of fans is of fundamental importance in many applications where it is necessary to regulate speed and airflow. This type of control offers various advantages depending on the context in which it is used.

Energy Efficiency: Active control allows for the adjustment of fan speed based on actual ventilation needs. This means that fans can operate at lower speeds when the demand for airflow is lower, saving energy and reducing operational costs.

Comfort and Indoor Air Quality: In building cooling and ventilation systems, active control helps maintain a comfortable indoor environment by adjusting fan speeds to avoid excessive drafts or sudden temperature fluctuations. It also helps maintain indoor air quality by effectively removing pollutants and allergens.

Noise Reduction:By reducing fan speeds when intense ventilation is not required, the noise generated by ventilation systems is also reduced. This is particularly important in noise-sensitive environments such as homes, hospitals, or offices.

Extended Fan Lifespan:The use of active control reduces wear and tear on fan components since they can operate at lower speeds with less mechanical stress when demand is low. This contributes to extending their lifespan and reducing maintenance costs.

Adaptation to Changing Conditions: Active control allows for adaptation to changing environmental conditions, such as temperature, humidity, or the presence of people in a space. This flexibility is crucial to ensuring optimal performance and a safe environment in different situations.

Enhancement of Industrial Process Performance:In industrial settings, active fan control is crucial to ensuring the proper functioning of production processes, product quality, and worker safety. It is used to control temperature, humidity, and the concentration of chemicals in the air.

At Meridiana Aspiratori we understand the importance of controlling industrial fans, which is why we rely on CEREBRO HumanDroid 4.0, a computerized brain designed to increase the safety and reliability of aspiration systems. It is a joint venture through which we pursue the same objectives, such as the constant pursuit of quality and operational efficiency.

Centrifugal fans are devices that move air or gas from one location to another, creating a negative pressure that draws the fluid into a filtration or ventilation system. Centrifugal fans are widely used in industry, for applications such as cooling, extraction, dust control, material handling and air exchange.

How centrifugal fans work

Centrifugal fans consist of a bladed impeller that rotates inside a drum-shaped casing. The impeller can have forward, backward or radial curved blades, depending on the type of performance required. The fluid enters the fan in an axial direction (parallel to the axis of rotation) and is accelerated by the impeller outwards, leaving the fan in a radial direction (perpendicular to the axis of rotation). The change in speed and direction of the fluid generates a change in pressure, which creates the air flow.

Advantages of centrifugal fans

Centrifugal fans offer several advantages over other types of fans, such as axial or helical fans. Among the main advantages can be mentioned:

  • High efficiency: centrifugal fans have a high efficiency, as they make best use of the mechanical energy supplied by the motor to transform it into kinetic energy of the fluid.
  • High Pressure: Centrifugal fans are capable of generating high pressure, even with low air flows. This makes them suitable for applications that require high pressure drops, such as filtration or cooling systems.
  • Low noise: centrifugal fans have a lower noise than other types of fans, as the fluid does not come into contact with the surfaces of the casing and the impeller is protected by acoustic shields.
  • Flexibility: centrifugal fans can be adjusted according to the needs of the application, by varying the rotation speed of the impeller, the number and inclination of the blades, the shape of the casing and thef connection to the system.

Industrial production plants produce a lot of hot air during daily production processes. Whether it's a metal forge, a paper press, a glass furnace or a compressor room, there is plenty of hot air. Fortunately, industrial fans are suitable for expelling hot air and improving the condition of the building.

 

Here are the main advantages of investing in industrial ventilation: industrial ventilation:

LOWER TEMPERATURES

Industrial ventilation equipment, such as fans and wall grilles, improves the building's airflow. Using the principles of natural ventilation, a vent on the roof expels suffocating air and the wall vent injects fresh air. This increase in air exchange makes the structure cooler and more comfortable. The right industrial ventilation system allows temperatures to be lowered by 1°C or more.

  1. REGULATION AND CONTROL

    One of the key advantages of installing industrial fans is the ability to control the entire airflow inside the facility. Whether it's a simple control switch or fully automated controls, an intelligent solution allows precise air control, allowing you to adapt to production variations, internal temperatures and external factors, creating a comfortable working environment.

     

    INDUSTRIAL VENTILATION SAFETY

    High temperatures can create a number of problems. From dehydration to equipment deterioration, the risks are numerous. Lower temperatures help protect workers and mitigate indoor pollution levels.

     

    NEGATIVE EFFECTS OF POOR VENTILATION

    The likelihood of an immediate reaction to poor air quality depends on several factors, such as age and the possible presence of existing diseases.

    Some effects may only occur in the years following prolonged exposure to poor ventilation, including respiratory disease, heart disease, and cancer. In some cases, these problems can be fatal.

    However, it can be difficult to pinpoint a specific concentration or period of exposure that may produce health problems due to poor ventilation, while the likelihood of significant long-term health effects varies from person to person.

    For these and other reasons, proper ventilation is essential to ensure worker safety.

It's easy to install ventilation equipment and think you're done, but like anything designed to protect workers' health, proper scheduled maintenance and service are critical if you want to ensure it continues to work well over time.

So, what are the benefits of scheduled and preventive maintenance?

  1. The ventilation system works best. If a plant is clean, it will operate at full capacity, as there will be no friction with dust, dirt and other debris that can inevitably end up in the plant.

  1. Management costs,

They are significantly reduced if you follow a planned preventive care regimen, instead of dealing with failures on a case-by-case basis. Requesting interventions on a weekly basis is much more expensive than a scheduled maintenance service on your own needs.

 

  1. Fewer spare parts.

With failures come the costs of spare parts, as the system is often not repairable. A dedicated staff member will have to continually tidy up spare parts when their time could be better spent on other tasks. Not to mention the costs involved in the continuous reordering of new spare parts.

 

  1. User errors or training gaps can be identified.

This could be the cause of all kinds of problems, such as extra pressure on the system. Operator training is essential and can help ensure that systems do not break.

 

Taking into account these activities, the staff will have the right tools and skills to use the machinery correctly and to keep it clean, and maintenance will be scheduled in advance in order to always guarantee maximum efficiency, so as to allow the company to continue to grow.

Transition 4.0 2022 confirms, and extends, the tax relief model started in 2017 for innovative interconnected assets, referred to as 'Industry 4.0' assets.

Industrial suction and cooling systems, if equipped with filtration, are in fact included in the tangible assets 4.0 Annex 'A' of the budget law, for which the incentive is confirmed to the extent of 50 per cent (no longer 40 per cent) of the purchase cost of the complete system with a total value of up to EUR 2.5 million.

The term Industry 4.0 refers to the process of industrial automation that aims to create smarter, faster and more efficient production departments. In other words, the goal of this 4th industrial revolution is to implement a series of transformations to achieve smart, automated and networked production systems.

A new way of producing and organising work, that of Industry 4.0, thanks to a mix of advanced technologies covering four fundamental digital aspects:

  • Data collection and analysis. Application of predictive analysis technologies such as machine learning, thus enabling maintenance that anticipates and prevents breakdowns and plant shutdowns.
  • Connections between machines thanks to technologies such as cloud computing, machine-to-machine and the Internet of Things;
  • Human-machine interaction made even simpler and more intuitive by touch interfaces;
  • Technologies that make the transition from digital to real, such as 3D printing and robotics.

 

But which air extraction and air treatment systems are eligible for Industry 4.0 concessions?

  • All the centralised suction systems for the purification of fumes, dust or fumes provided that a filtration system is present, e.g. with bag or pocket cartridges. The reason is very simple: in addition to having a plant->company interface, the 4.0 system must be able to monitor in real time the status of the filters and any other components such as probes, solenoid valves, etc.
  • All the industrial air treatment plantswith particular reference to cooling systems intended for air conditioning of warehouses or large buildings, of great interest to our customers who wish to operate machinery and operators in a temperature-controlled environment.

As a rule, fans are sized and installed according to maximum ventilation requirements, but maximum ventilation capacity is not always necessary, as the installation of an inverter allows the speed of the fan motor to be controlled to meet actual ventilation needs. Reducing the motor speed reduces the amount of energy needed to power it (up to 8 times), which in turn reduces costs and consequently co2 emissions.

When connected to a sensor system, inverters can be even more effective by controlling motor performance according to any number of predefined settings such as temperature, flow, humidity, etc., eliminating the need for manual adjustment.

How does an inverter work?

Frequency manipulation with an inverter consists of converting the incoming mains voltage from AC to DC using a full-wave rectifier circuit. There is then a second DC link stage that smooths out the waveform and ensures that the inverter remains charged while in use. The final stage involves creating a pulsed square-wave voltage output to simulate an AC waveform as shown below:

Inverters can play a key role in energy-saving projects, but the benefits do not stop there. Reducing the amount of time the motor runs at full speed will not only save energy, but also reduce the strain on the motor itself and any connected components. This means less maintenance requirements and, once again, a reduction in costs. Installing an inverter on an older system that is prone to wear and tear can even help extend its service life.
