Farm building ventilation duct

for silos

Ventilation systems allow best preservation of ensilaged or warehoused grain. By keeping the temperature and humidity of the mass moderately low and consistent, storage is possible for a limited period of time, without deterioration caused by various phenomena such as respiration, fermentation and the spread of parasites. RAISED TOTAL VENTILATION The ventilation system features a raised perforated floor, supported by a galvanized steel structure. The air flow generated by a fan or chiller enters underneath the floor and rises upwards, cooling the product. DUCTED VENTILATION Ducted ventilation is widely used in newly constructed silos. The air flow generated by a fan or chiller enters the ducts and rises upwards, cooling the product. Storage residue can easily be cleaned off the ducts. PERFORATED CONE AERATION Perforated cone aeration is used in silos with a hopper. An economical system used to cool stored products. INVERTED CONE AERATION Inverted cone aeration is used in medium and low capacity silos. The air is inserted into the inverted cone and exits in the circumference. It rises upwards, cooling the product. CROSS VENTILATION Cross ventilation allows the insertion of air in four equal parts of the conical silo base. The air exits from the area below the cross and rises upwards, cooling the product.
