ATEX certification: a key element for exhaust fans in grain silos

ATEX (Atmosphere Explosible) is the designation of the European Directive on safety at work in explosive atmospheres. It sets out safety requirements for all equipment with a potential explosion risk in industrial environments, including silo exhaust fans. With the increasing demand for safe and efficient storage systems, an ATEX certified exhaust fan is essential to protect your investment and maintain the quality of your stored commodities.

Safety at the top of the grain silo

The upper part of the silo contains a large amount of dust that can create an explosive environment. Exhaust fan motors should be rated for Zone 22 or 21, which means that they are designed to carry dust and not be a source of an explosive environment.

ATEX certification for electric motors

ATEX certification also contributes to the long life and durability of electric exhaust fan motors. Certified equipment is built to withstand harsh conditions and continuous operation, reducing maintenance costs and ensuring optimum performance for longer periods of time.

The importance of ATEX certification for exhaust fans

ATEX-certified electric exhaust fan motors in silos are required to ensure safety, efficiency and optimum performance. This certification not only minimises risks but also contributes to the longevity of your storage equipment.  

Grain silos safety: EUROCODE as a key standard in the EU

Standards are an important part of silo design and construction. Different standards may have different requirements for structural elements and materials, which can affect the overall safety and functionality of the silo.

Standards in the European Union: EUROCODE

In the European Union, the most commonly used standard for building design is EUROCODE, which is harmonised and valid throughout the EU. Conformity assessment according to this standard is therefore mandatory in the EU and silos should be designed and built in accordance with its requirements.

Standards in other countries: the ANSI and other guidelines

Other countries use their own standards, such as ANSI in the USA and other guidelines that have their own specific requirements for silo design and construction. The EUROCODE standard for grain storage silos, which specifies the safety and reliability of structures, is a key consideration for any company involved in the storage and handling of agricultural commodities.

Grain storage silos: certification and safety

Grain storage silos are essential to preserve the quality and value of agricultural commodities. EUROCODE certification ensures that these silos are designed and manufactured to the highest safety standards. This includes factors such as structural integrity, load-bearing capacity and resistance to natural disasters such as earthquakes and high winds.

Planning and construction of grain storage silos: applicable standards

When planning and constructing a silo, it is important to always take into account the applicable standards and guidelines in the area to ensure the safety and functionality of the silo and to minimise the risks associated with its operation.  

Large upper platform at grain storage silos: the key to human safety

The top landing is a key element of the storage silo, providing safe and easy access to the staircase and top hatch.

Enlarged platform: minimum size for safe access

For the safety of workers moving around the storage silo and climbing to the upper platform, we recommend an enlarged platform with a minimum size of 1.7 m. With a sufficiently large surface area, stable and solid support for the legs can be provided, allowing easy and safe access to the staircase and the top hatch. It is essential that the upper platform is designed and constructed with this safety issue in mind and that it meets all relevant standards and norms for storage silos.

Screw conveyor motors for grain storage silos: the advantages of outdoor positioning

The silo unloading uses screw conveyors controlled by a single motor. You can choose whether you want the motor inside or outside the silo.

The importance of the location of grain storage engines

The correct positioning of the screw conveyor motors for grain storage silos is essential for efficient and trouble-free operation. Locating these motors outdoors offers several advantages and is therefore the preferred choice in many situations.

Key advantages of outdoor motor placement

One of the key advantages of an outdoor location is ease of maintenance and accessibility. By locating the screw conveyor’s discharge motors outside the silo, technicians can easily perform routine inspections and repairs without having to enter enclosed areas.

Prevention of overheating and grain contamination

The outdoor location of the motors also allows for better heat dissipation, reducing the risk of overheating and extending the life of the motor. This arrangement also minimises the risk of grain contamination as the motor is not in direct contact with the stored grain.

Recommendations for engine placement

It is recommended that the engine be located outdoors to avoid dangerous build-up of gases in the event of a fire and to ensure that the engine is easily accessible for repair or maintenance. If you choose to place the engine inside a silo, it must be of ATEX design to meet safety standards. This step is essential to ensure the safe and efficient removal of the silo.

From galvanizing to exhaust fans: how to choose a grain storage silo supplier

The acquisition of a new storage silo is a significant investment. For the safety and quality of the stored goods, it is essential to pay attention to all parts of the silo. In addition to the galvanizing, roof, staircase, doors and floor, the fans and motors must also be addressed. It is important to choose a quality storage silo that is certified according to current standards to ensure maximum protection against fires and other risks.

Supplier selection: key components and quotation

Choosing a supplier that offers all these key components and includes them in the first version of the quotation is crucial. This is the only way to avoid paying unexpected costs later in the process.

What to expect from a quality supplier

A quality supplier is able to offer a wide range of sizes and force configurations to meet your specific needs. They should also provide expert guidance and advice to help you select the right silo for your operation. In addition, they should be committed to providing quality customer service and ensuring that your silo is properly installed and maintained. So when you’re ready to purchase one or more grain storage silos, make sure you choose a supplier that is committed to providing you with the highest quality solutions available. With the right silo and supplier, you can rest assured that your grain will be well protected and secured for years to come. Remember, the investment you make today in a quality storage silo will pay off in the future because your grain will remain safe.

Conclusion: a comprehensive approach to selecting storage silos

Overall, when choosing a storage supplier, it is essential to prioritise not only the quality of materials but also comprehensive features and services. These too can significantly impact the longevity, safety and efficiency of your investment. As we have described in these articles, proper galvanization of storage silos, reinforced roofs, staircases, large doors, aeration fans with the right performance and ATEX certified exhaust fans all play a vital role in ensuring maximum protection and longevity of your storage silos.
