Floor ventilation

System Overview:

• Consists of channels embedded in the concrete foundation of the silo or warehouse floor

• Channels are interconnected and covered with ventilation planks featuring special construction and perforation for maximum airflow and cooling

Aeration planks

• The most important element of the floor ventilation system

• Different designs for silos and flat warehouses:

  • Silo grilles are built to withstand the weight of the grain

  • Warehouse grilles are designed to support grain plus heavy machinery such as loaders, grain trucks, and trailers

• Typical load capacity for flat warehouse planks: 10–16 tons per axle

• Planks vary depending on the type of stored product:

  • Larger openings for coarse grains like corn, chickpeas, beans

  • For mixed storage, the smallest grain size determines the planks specification
     

    Concrete Channels

  • The layout and type of channels in the concrete foundation are critical for proper ventilation

  • Channels are constructed during building phase based on a predefined scheme

  • SLAV-VERIGI Ltd., a leading manufacturer of grain ventilation systems, offers ready-made metal formworks for embedding in the floor:

    • Minimizes construction errors

    • Improves airflow

    • Simplifies cleaning and maintenance
       

      Ventilators

    • Proper ventilator selection and installation is essential for system performance

    • SLAV-VERIGI’s engineering team provides expert guidance based on years of experience in grain and bulk product ventilation
       

      Key Advantages of Active Floor Ventilation

    • Large ventilation opening area: 11% to 26% of total aeration surface of the planks

    • Ventilated floor coverage: from 15% up to 100% of silo or warehouse floor

    • Grille variety: perforated, elongated slots, framed or frameless – tailored to grain type

    • High load capacity: 7 to 16 tons per wheel – allows machinery to operate directly on top

    • Warehouse filling with vehicles: trucks, loaders, etc.

    • Easy cleaning: no upper edge to trap debris

    • Simple installation

    • Full control when combined with temperature monitoring systems
