In many floor and wall tile factories, dust issues can reach levels that threaten both the health of workers and the machines. However, there are also many facilities operating with near-zero dust levels.

Key topics related to dust elimination can be analyzed as follows:

Dust Collection Systems

Dust collection systems are primarily divided into two categories:

• Floating dust collection
• Sweeping systems

Floating dust consists of particles under 20 microns generated in areas such as raw material transfer points and press conveyor belts. The goal of traditional dust collection systems is to capture this dust. The extraction of larger particles is not desirable to prevent product loss. Therefore, snail fans operating in the 3,500–4,500 Pascal range are commonly used.

Sweeping systems are generally employed to collect granulated materials up to 10 mm in size, using blowers operating at -40,000 Pa vacuum power. Consequently, there is nearly a tenfold pressure difference between floating dust collection systems and sweeping systems.

One of the most common mistakes in ceramic plants is attempting to clean floors using dust collection units with fans. Similarly, connecting the discharge chutes of press rear slides to the floating dust collection system is another error. Sweeping operations must be conducted with high-pressure systems. Otherwise, coarse granules being transported can accumulate in dust collection lines, causing blockages. Clogged pipes render the system non-functional.

Correct Capture Speed in Front of Press Hoods

Using the correct capture speeds in front of press hoods is crucial. Pressurized air blown onto molds generates significant dust, making cross-sectional speed a critical factor for the hood to effectively capture this dust.

Effective Dust Removal in Raw Material Feeding Systems

Dust removal on press feed conveyors is often neglected because these areas are not visible. In most facilities, white-collar workers rarely inspect these areas, resulting in knee-deep dust accumulation.

Having high-pressure vacuum lines for cleaning this area is essential. Manual cleaning requires significant personnel effort and time, leading to neglect. Consequently, accumulated dust continuously falls onto the press floor. However, when a high-pressure vacuum line is implemented, cleaning can be performed quickly by a single operator.

Use of Next-Generation Dust Collection Systems

In facilities with heavy dust loads, such as presses, using next-generation, high-efficiency dust collection systems is crucial.

Dust collection systems used in industrial production processes play a critical role in improving production efficiency while ensuring occupational health and safety. The efficient and long-lasting use of filters in these systems directly affects dust collection performance. So, how can you extend the lifespan of your filters and maintain the efficient operation of your system? In this blog post, we discuss essential tips and technical details for the long-lasting use of filters in industrial dust collection systems.

1. Choose the Right Filter

The first step to extending the lifespan of filters is selecting the correct filter type. Each industrial application may involve different dust characteristics. Factors such as particle size, density, and moisture content of the dust directly influence filter selection. Different filter types, such as cartridge filters, bag filters, or HEPA filters, should be chosen according to the specific needs. Properly selected filters not only ensure more efficient dust collection but also prevent excessive wear on the filter.

2. Perform Regular Filter Maintenance

Regular maintenance of filters is crucial for long-term use. To maintain the filtration performance of your dust collection system and prevent filter clogging, routine cleaning is essential. Modern systems with automatic cleaning features, like jet-pulse cleaning systems, keep filters consistently clean and reduce maintenance frequency. However, manual checks and cleaning processes should not be neglected.

3. Prevent Overloading the Filters

Operating dust collection systems under conditions that excessively burden filters can significantly shorten their lifespan. Continuous exposure to heavy particles can cause clogging and wear on the filters. Airflow and suction power of the system should be adjusted according to the filters’ performance capacity. Regular checks of the system’s suction capacity are important to avoid overloading the filters.

4. Use Advanced Filter Cleaning Technologies

Jet-pulse cleaning technology, used in modern dust collection systems, ensures filters remain clean for long-lasting use. This technology cleans accumulated dust on the filter surface using powerful air pulses, preventing clogging and performance loss. Additionally, automatic cleaning systems optimize the maintenance process and enhance the lifespan of the filters.

5. Use High-Quality Materials

The quality of the materials used in filters is crucial for their durability. Industrial filter cartridges must withstand high temperatures, humid environments, and abrasive dust. Filters provided by Asel Teknik are made of high-quality materials designed for long-lasting use even under demanding industrial conditions. High-quality filter materials resist wear and help the filters remain effective for a longer time.

6. Replace Filters Properly

Safe production in the industrial sector is critically important for both occupational safety and the sustainability of businesses. Particularly in facilities with environments at risk of explosions, various technological solutions have been developed to minimize these risks. One such solution is Exproof (Explosion-Proof) Technology. This article will examine in detail what Exproof technology is, why it is important, and the methods used to reduce explosion risks.

What is Exproof Technology?

Exproof technology refers to the special precautions applied in the design of equipment and devices used in environments with potential explosion risks. This technology ensures that electrical and mechanical devices operate without allowing heat, sparks, or electrical currents that could cause an explosion to affect the external environment. Thus, a safe production environment is established in areas with hazardous atmospheres.

Key Elements of Exproof Technology

• Protective Enclosures: Devices are equipped with enclosures designed to contain potential explosion sources. These enclosures prevent the internal heat of the device from being transferred to the external environment.
• Gas Pressure Method: The air pressure inside the device’s enclosure is maintained at a higher level than the dangerous gas pressure outside, preventing hazardous gases from entering the device.
• Abrasive Protection: Device surfaces are coated with special materials to ensure tight sealing, preventing the passage of particles or gases.
• Increased Safety Method: Electrical components inside the device are designed to keep their temperature below the explosion threshold.

Methods to Reduce Explosion Risks

Exproof technology is implemented using various methods and standards. Below are the main approaches used to mitigate explosion risks:

1. Area Classification and Risk Assessment
   Before implementing any Exproof solution, it is essential to determine whether the facility’s area poses an explosion risk. Area classification considers factors such as atmospheric conditions and the presence of flammable gases or dust. Risk assessment analyzes potential explosion scenarios and their impacts.
2. Selection of Appropriate Exproof Equipment
   Based on the area classification, the equipment used must comply with the relevant Exproof classifications. For example, if an area is designated as Class I, Division 1 (high explosion risk), the devices used in this area must have the appropriate certifications.
3. Regular Maintenance and Inspection
   The effectiveness of Exproof systems depends on regular maintenance and inspection. Over time, enclosures, sealing elements, or other components may degrade, posing explosion risks. Therefore, periodic inspections and maintenance are crucial.
4. Training and Awareness
   Educating facility workers about Exproof technology and explosion risks is essential for maintaining safe production processes. Workers must be knowledgeable about equipment usage, emergency procedures, and potential hazards.
5. Integrated Safety Systems
   Exproof technology can be integrated with other safety systems for enhanced protection. For instance, fire detection systems, ventilation controls, and automatic shut-off valves play a significant role in reducing explosion risks.

Advantages of Exproof Technology

• Safe Working Environment: Ensures the safety of workers in environments with explosion risks.
• Continuous Production: Minimizing explosion risks reduces production interruptions and increases efficiency.

In our daily lives, various gases are constantly present around us in different proportions. Among the most common ones are oxygen and nitrogen in the air we breathe, methane used for heating and cooking, and carbon monoxide and carbon dioxide emitted from vehicle exhausts. Due to their nature, some gases are flammable, some are toxic, and some can be both. In the past, the lack of necessary precautions in industrial facilities has led to significant accidents resulting in numerous losses.

To prevent such incidents from recurring, various steps have been taken, leading to the establishment of global standards. ATEX (ATmosphères EXplosives) is one such standard adopted by many countries outside North America. The ATEX coding system consists of specific letters and numbers:

• Zone 0: Areas where explosive atmospheres, created by the mixture of flammable substances in the form of gas, vapor, or mist with air, are continuously or frequently present for extended periods.
• Zone 1: Areas where explosive atmospheres, formed by the mixture of flammable substances in the form of gas, vapor, or mist with air, are likely to occur occasionally during normal operations.
• Zone 2: Areas where explosive atmospheres, caused by the mixture of flammable substances in the form of gas, vapor, or mist with air, are not expected under normal conditions or may occur only for a very short period.
• Zone 20: Areas where combustible dust is present in the air as a cloud, continuously, frequently, or for long periods, potentially forming an explosive atmosphere. In such environments, prolonged suspension of dust particles in the air increases the risk of an explosive atmosphere. Proper ventilation systems are crucial, especially in processing or manufacturing environments where dust is continuously released into the air.
• Zone 21: Areas where combustible dust, present in the air as a cloud under normal operating conditions, may occasionally form an explosive atmosphere. Dust accumulations in production processes may lead to explosive atmospheres, necessitating regular cleaning and dust control measures in these areas.
• Zone 22: Areas where combustible dust in the air as a cloud is unlikely to form an explosive atmosphere under normal operating conditions or may do so only for very short periods. However, care must be taken due to the potential suspension of dust in the air during accidents or malfunctions.

Industrial fans in such potentially hazardous environments must be designed to operate safely and reliably. For instance, devices suitable for Zone 0, offering the highest level of protection, can also be used in Zones 1 and 2. Similarly, devices certified for Zone 1 are suitable for Zone 2 as well.

Ensuring that industrial fans comply with ATEX standards is crucial not only for protecting workers’ health but also for maintaining uninterrupted and safe production processes. ATEX 137 defines the minimum requirements for protecting workers’ health and classifies areas with a potential for explosive atmospheres. Therefore, proper certification and use of equipment like industrial fans in the appropriate zones are critical for workplace safety.

At Asel Teknik, the compliance of our industrial fans with ATEX standards plays a significant role in enhancing workplace safety and managing potentially explosive environments. Creating safe working areas is not only a legal requirement but also an obligation for ensuring the health and safety of our employees. By keeping up with developments and innovations in our sector, we aim to consistently provide the most reliable solutions.

Sustainable production is becoming increasingly important in today’s industrial world. Businesses must develop new strategies to reduce their environmental impact and enhance energy efficiency. In this context, effective dust collection systems play a critical role in both occupational health and environmental protection.

The Importance of Dust Control

During production processes in industrial facilities, the dust and particles generated can threaten employee health and damage equipment. Effectively controlling harmful substances in the air contributes to the sustainability of businesses. A good dust collection system not only enhances efficiency in production processes but also helps ensure workplace safety.

Innovative Solutions

Developing innovative dust collection solutions is essential to achieving sustainable production goals. Modern systems provide high efficiency and low energy consumption, reducing costs for businesses while minimizing environmental impact. Advanced filtration technologies ensure effective collection of dust and particles, thereby improving air quality.

Energy Efficiency and Environmental Sensitivity

Energy efficiency is a cornerstone of sustainable production strategies. Advanced dust collection systems minimize energy consumption while enhancing performance, contributing to more efficient production processes. These systems enable businesses to reduce their environmental footprint and increase workforce productivity.

Planning for the Future

Sustainability is not only a current concern but also a vital issue for the future. Industrial facilities must continuously innovate to reduce their environmental impact and enhance efficiency. Dust collection solutions hold a significant place in this process and play a critical role in helping businesses achieve their future sustainability goals.

Sustainable production requires balancing environmental protection with operational efficiency. Advanced dust collection systems protect employee health while helping businesses reduce their environmental impact. The adoption of these systems allows industrial facilities to take a step toward a healthier, safer, and more sustainable future.

When considering industrial fans, higher revolutions per minute (RPM) might seem to indicate a better machine. However, RPM is often less significant compared to other features. For instance, the effectiveness of the cleaning process is not necessarily related to the RPM, and users generally operate at lower speeds to avoid wrinkles.

Economic Sustainability

The main consumption items in a dust extraction system are:

• Electricity Consumption by Fans
• Electricity Consumption by Compressed Air
• Consumables for Dust Filter Elements
• Electricity Consumption due to Efficiency Losses
• Maintenance Costs due to Design-Induced Excessive Wear

While purchasing a dust extraction unit economically is important, maintaining that economic efficiency during use is equally critical. Incorrectly selected fans, units with excessive compressed air consumption, designs that overload filter elements with dust, and designs that cause excessive wear and tear can all undermine operational economics.

Sustainable Performance

A common issue with dust collection units is that they perform well for the first three months but then fail. Units that consume energy but do not collect dust effectively are problematic. Many poorly designed dust collection systems cannot maintain even half of their initial airflow after a few months of operation. Consequently, at least half of the money spent may be wasted. The damage caused by uncollected dust to people, machines, and the environment adds to this issue.

Environmental Sustainability

Dust collection units interact with the environment in several ways, including the disposal of used filter elements, energy consumption efficiency, and the ability to capture harmful dust. Therefore, their initial design has a direct impact on the environment. Ultimately, unit consumption values are among the critical criteria that should be measured.

Radial fans are crucial equipment used widely in various industrial and commercial applications. The types and characteristics of these fans vary to suit specific functions and applications. Radial fans, in particular, hold an important place in this category. In this article, we will examine the different classes of radial fans, their effectiveness in various applications, and their features related to quiet operation and energy efficiency.

What is a Radial Fan?

Radial fans are a type of fan used to provide airflow. In other words, the air is pushed out from the rotor of the fan. These fans are typically preferred for applications requiring high pressure. Radial fans are divided into three main classes: Straight Radial, Backward-Curved, and Forward-Curved.

Straight Radial

Straight radial fans have blades that extend straight outward from the center. Radial blades are often used in particle-laden gas flows because they are less sensitive to solid matter buildup, but they are generally characterized by higher noise output. Straight radial fans operate at high speeds, low volumes, and high pressures and are frequently used in vacuum cleaners, pneumatic material handling systems, and similar processes.

Backward-Curved

Backward-curved blades are angled opposite to the direction of rotation of the fan wheel. Smaller fans may have straight, non-curved backward blades. Larger backward-curved fans feature blades with airfoil profiles that mimic backward curves, but both designs offer good operational efficiency with relatively economical construction techniques. These fans are designed to handle gas flows with low to moderate particle loading. They can be easily equipped with abrasion protection, although certain blade angles may be prone to solid matter accumulation. Backward-curved fans are generally heavier than their forward-curved counterparts because they operate at higher speeds and require a more robust structure.

Backward-curved fans can have specific speed ranges but are most often used in applications requiring medium flow rates and high pressure, such as air handling units. They are more energy-efficient than radial and forward-curved fans, making them a cost-effective alternative for high-power applications.

Forward-Curved

Forward-curved blades are angled in the direction of the fan’s rotation. These blades are particularly sensitive to particles and are typically designated for clean air applications, such as in air conditioning systems. Forward-curved fans are used in applications requiring high static pressure where an axial fan with a single blade is inadequate or where a centrifugal fan’s small size is needed but the noise characteristics of a backward-curved fan would be disturbing. They can provide lower airflow but achieve a higher increase in static pressure compared to an axial fan with a single blade. They are commonly used in fan coil units. Forward-curved fans are less efficient compared to backward-curved fans.

Quiet Operation and Energy Efficiency

At ASEL Teknik, we are pioneers in developing systems for radial fans that ensure quiet operation and energy efficiency. These systems feature high-efficiency motors, aerodynamic designs, and advanced control algorithms. As a result, the fans operate quietly and efficiently, minimizing energy consumption.

Applications

Radial fans, with their various classes, are ideal for different applications:

• Ventilation Systems: Both straight and forward-curved radial fans, along with snail designs, can be used in ventilation systems in buildings and industrial facilities.
• Air Conditioning Systems: Particularly straight and forward-curved radial fans are used for air circulation in air conditioning systems.
• Industrial Processes: Backward-curved radial fans are preferred in industrial processes requiring high pressure.
• Cooling Systems: Forward-curved radial fans can be used to enhance airflow in cooling systems.

Radial fans, categorized into different classes, cater to various application areas. The straight, forward-curved, and backward-curved designs of radial fans are tailored to meet specific pressure and flow requirements. Systems that provide quiet operation and energy savings are essential features of modern fans.
