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.

2. 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.

3. 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.

4. 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.

CEREBRO™'s predictive and reactive system operates on the basis of a series of algorithms that manage, sometimes even overlapping to increase capacity and calculation accuracy, entire process systems. Eolo System, for example, is responsible for managing variable speed with constant pressure or temperature. Its predictive capacity analyses every second the point of operation during atmospheric emissions from tribo probes, or the clogging status of filtering systems, and thanks to the StepHertz function it allows an acceleration scale to be defined on the basis of what is set in the frequency converter, but definable directly by the system operator, who is the only one who really knows how to make his machinery work at its best.

Within reach of the operator in real time

Cerebro was developed with a view to making the technology we already have available flexible and usable. The software, therefore, is a user interface within the reach of any operator, always active and compliant with all the latest operating systems and hardware, and ready for operation with LAN or 3G/4G connection. Thanks to this technology, the maintenance technician can check the health status of the filters at any time, modify the firing latency times for pneumatic cleaning, switch from automatic to manual mode or control the pause times for post-cleaning. All from the phone or computer.

Its SSL-encrypted protections and crash recovery support site without direct bridge to the end user guarantee the usability of the product and the highest possible security, making it an irreplaceable companion in the working day of all those operators responsible for the safety and functionality of process systems, for multiple companies of even radically different sizes and characteristics. Changing the parameters of a frequency converter without having to open the switchboard door with the danger of working under voltage? Today it can be done. CEREBRO™ offers several options in setup, including parameter modification from the outside, and above all remotely for the frequency converter, for the operator panels and numerous external devices with variable functions according to user needs. How could it be missing in such a health-conscious system? eMI will instantly update us on what is happening out of the ordinary with an instant decoding of the drive's error message. All elements under its control will be viewable and any abnormal intervention, from thermal trip to exceeding the warning threshold for filter pressure, will be displayed.AirFlow will allow us to check and monitor the characteristic curve of the fan and the working point of the system. The system works exclusively with the pre-loading of the curve information provided by MZ Aspiratori SpA.

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.

Regulating temperature and air quality in large commercial and industrial spaces can be difficult. Proper ventilation and airflow are essential to help maintain consistent temperatures throughout the space and keep operating costs down.

Fans are commonly used to help cool and ventilate large spaces, but not all fans are up to the job or work effectively. It is therefore important to choose a fan that has been designed for this type of application.

What makes an industrial fan different?

There are two types of fans available on the market today, general purpose fans and industrial fans. At first glance they may seem identical, but there are substantial differences:

Durability: Industrial fans are built to last under heavy and continuous use. General purpose fans, on the other hand, are designed for lighter and/or intermittent use in homes or offices. The difference is in the details. An industrial fan is characterised by stronger materials and bearings, stronger welds and construction, and a more powerful motor, allowing it to last longer and maintain its performance over time.

Size/Capacity: Industrial fans are usually larger, and therefore capable of generating more pressure, with airflows of up to 100,000 m³/h.

Why are larger industrial fans more suitable for large spaces?

Better air flow: It takes up to 34 small conventional fans to do the job of one large industrial fan. The column of air produced is able to move more efficiently around obstacles, distributing the air throughout the space.

Lower energy costs: For the same volume of air, an industrial fan requires much less electricity than a number of small fans, leading to considerable savings.

Quieter working environment: Small fans need a high operating speed and are therefore noisier. A suitably sized industrial fan, on the other hand, can move large volumes of air effectively even at lower speeds, while remaining quiet. The result is greater comfort for employees and improved productivity.

An industrial fan can make a huge difference to your facility's energy bills, safety and productivity. Investing in a quality industrial fan is a value-based decision that will reward you for years to come.

In the relevant markets, the term 'industrial fan' does not have a clear definition and in this article we want to explain what industrial fans are, specifically axial and centrifugal models and their differences.

An axial fan is a fan in which the extracted air is forced to move parallel to the shaft around which the blades rotate. Centrifugal fans, on the other hand, extract air perpendicular to the fan inlet, and spin it towards the outlet due to deflection and centrifugal force. The impeller rotates, allowing air to enter the fan near the shaft and move perpendicularly from the shaft towards the opening in the fan casing.

Axial fans replace the centrifugal fan in certain fields of application from a functional point of view, operating at higher specific speeds with smaller diameters.

An axial fan, with the same flow rate and pressure, has the following differences to a centrifugal fan:

• has a smaller impeller diameter
• has a higher dynamic pressure
• has a significantly higher operating speed
• the peripheral speed is greater
• has lower efficiency and therefore higher energy consumption
• is much louder
• is significantly smaller and lighter, and less expensive

The most significant data in this comparison are weight, operating speed and noise. The operating speed comparison shows that the same flow and pressure characteristics can be obtained from axial fans at higher operating and peripheral speeds than centrifugal fans. Since there is a limit to the stresses in the rotating bodies, and hence to their peripheral speeds, we can safely say that pressures of a certain magnitude are more easily obtained with centrifugal fans than with axial fans.

Axial fans are generally noisier and it is often the case that an axial fan requires the use of silencers to reduce noise, whereas a centrifugal fan would not.

But these negative aspects are countered by a lower weight, less space occupied, a lower cost and the parallelism of the two suction and discharge nozzles, which make it easy to fit into the system, where the axial fan becomes nothing more than a piece of pipe, while the centrifugal fan requires a more complex solution.
