Steel silos protect grain from the outside environment—but they cannot control the internal storage climate.

During the day, the sun heats the silo walls. At night, the metal cools rapidly, causing moisture to migrate and condense within the grain mass. This continuous cycle creates localized hot spots where mould, insects, and microbial activity thrive, leading to spoilage, self-heating, unpleasant odours, and irreversible grain quality loss.

Conventional aeration is an effective storage method when the outside air is naturally cool and dry. In many temperate regions, it can successfully reduce grain temperature using ambient air. However, in tropical, subtropical, and arid climates, the ambient air is often too warm, too humid, or both. Under these conditions, aeration alone cannot consistently achieve the safe grain temperatures required for long-term storage.

GrainVault™ solves this challenge with true mechanical grain cooling. Independent of ambient weather conditions, it maintains stable grain temperatures and intelligent moisture control, transforming conventional silos into climate-controlled storage environments that protect grain quality, reduce storage losses, and preserve the value of every tonne.
