   Aeration spear

Replaces hot air with cool air! Ideal for cooling grain harvested under relatively dry conditions

  • The standard length of the drill tube is two meters and can be extended to a maximum of 4 meters. Longer drill tubes would require too much force to drill into the grain
  • This device has been tested by an official Danish research institute with the following results:
    • The spear can cool approximately 100 tons of grain per position
    • Measured at a radius of 3 meters the aeration level is still 30 m³ of air per hour per m² surface. This is sufficient for storing grain with a moisture content of 17% to 18%;
    • In a 7,5 meters high silo it was established that after 22 hours the spear had cooled the grain from 22 to 18 degrees at the top and from 28 to 20 degrees at the bottom. This confirms what we already know: the heavier cold air will always descend and replace the lighter warm air
  • Fan: 1,1 kW, 2.800 RPM, output 1.500 tot 1.700 m³ per hour approximately
  • Perforated bottom section (1,5 mm)
  • Complete with accessories for drilling; cable and plug are optional
  • Total weight 23,9 kg

Aeration floors are the ideal solution if you need to be able to empty your storage compartment. The grids are strong enough to withstand the load of heavy vehicles like trucks. For the installation of the aeration channels you may take care of all the necessary preparations before the grids are installed. Alternatively, we can provide steel gutters which can be placed as the concrete floor is cast.
