In today’s agricultural storage management, accessories have become indispensable for achieving optimal performance and protection. At Prado Silos, each project is engineered as a comprehensive solution tailored to its environment, where all components — from precision ventilation systems to durable access structures — contribute to superior efficiency, safety and long-term durability.
Prado Silos’ mission is not only to provide the most advanced grain storage solutions — it is about ensuring intelligent design, safety and precision in every detail. For this reason, the accessories developed by Europe’s most experienced silo manufacturer enable every installation to be adapted to the specific working conditions and production objectives of each client. Below, we outline the main accessories that can be installed on metal silos, describing their functions and how they enhance maintenance, grain preservation and daily operational reliability.
One of the primary operational needs is ensuring safe access to the silo. Reaching the internal or elevated areas of the structure demands strict safety measures. Prado Silos offers an extensive range of doors, ladders and access systems within each customised project to guarantee ease of inspection, safe maintenance and long-term reliability.
Access doors are specifically designed according to the task and safety requirements of each silo. The roof inspection door enables operators to check the condition of the grain and the ventilation systems without opening the structure, ensuring continuous control and protection. Meanwhile, the double door on the ferrule provides easy access for cleaning or inspection personnel, while large-scale facilities benefit from a dedicated machinery door, designed to allow the entry of maintenance and handling equipment.
Ladders and access platforms are essential for maintaining, inspecting and upgrading silo facilities. Prado Silos offers a complete range of solutions — such as internal and external vertical ladders, spiral or zigzag configurations, roof ladders and connecting platforms between silos — allowing secure and efficient operator routes. Structural walkways and support systems are designed to link access points while preserving the strength and stability of the overall structure.
Ensuring structural strength is essential for the durability and reliability of any metal silo installation. Prado Silos designs robust support structures fully adapted to the project’s environment and operational workflow, including walkways, supporting columns, dome reinforcements and lift towers.
Beyond the primary silo construction, Prado Silos supplies complementary structural elements designed to reinforce key areas and integrate grain handling or distribution systems. In multi-silo configurations, these structures play a vital role in coordinating grain flow and maintaining the mechanical balance and durability of the entire installation.
Effective management of temperature and humidity inside a metal silo is crucial for safeguarding grain quality over time. Prado Silos applies tailored ventilation and aeration solutions that actively regulate the internal climate, ensuring consistent quality and long-term protection of stored products.
Available systems include aeration domes, air inlet channels, perforated floors, bottom fans and ceiling extractors. This equipment promotes uniform air distribution, preventing condensation and localised moisture that may damage the grain. When complemented by automated monitoring, these solutions maintain a balanced internal environment, extending storage life and reducing spoilage losses.
New technologies have also transformed the field of large-scale grain storage. Prado Silos integrates advanced control and monitoring systems that continuously track temperature, humidity and grain condition in real time.
Temperature sensors record thermal variations at multiple points within the silo and can be complemented by humidity probes or CO₂ detectors. The collected data can be linked to the aeration systems, allowing automated airflow management in response to changing internal parameters.
Further enhancing efficiency, level sensors provide real-time data on storage volume, while automatic sweepers ensure complete discharge by removing residual grain after gravity flow. As a result, the silo can be fully emptied without manual handling, simplifying subsequent cleaning and maintenance operations.
Each component of the silo plays a specific role — and cylinder and roof fittings are crucial to both performance and safety.
At the heart of the silo, the cylinder incorporates a gentle loading system that channels the grain carefully to avoid damage during filling. The side discharge provides direct emptying into a lorry or conveyor, while the smooth internal walls ensure optimal flow and easier cleaning, reducing the risk of material build-up.
On the roof, dome platforms and eave railings provide secure maintenance points, while upper walkways ensure safe access to the conveyors. The venting system protects the structure from overpressure, meeting the most stringent international standards. Further protection is offered by avalanche guards and eave skirts, designed to withstand adverse weather conditions.
In addition to conventional installations, Prado Silos designs customised solutions for projects with specific technical or environmental requirements. The double roof and double cylinder configuration ensures exceptional thermal insulation, particularly suitable for regions subject to extreme or fluctuating temperatures.
The hopper enclosure prevents moisture or dust from entering during unloading, while fumigation and inertisation systems allow precise control of the silo’s internal atmosphere, helping to prevent pests and grain deterioration without the use of harsh chemicals.
The true value of a metal silo extends beyond its steel panels or storage capacity; it lies in the seamless integration of structure and accessories. Access systems, ventilation, monitoring, flow management and protective features ensure the silo operates efficiently, preserves grain quality and maximises operational performance.
Prado Silos provides a modular, fully adaptable range of accessories, integrated from the outset and conceived as a complete, cohesive system. Combined with robust metal construction and ZM310 coating on all silo models, this approach delivers efficient, safe, long-lasting and future-proof storage solutions.
