At the heart of every Svalz Grain Vault lies a precisely engineered refrigeration circuit, developed with European precision and tropical endurance. Ambient air is drawn into the machine and filtered. It passes across a refrigeration coil where it is cooled and dehumidified. The conditioned air — now at a lower temperature and controlled humidity — is gently pushed through the stored grain mass via the existing aeration ducts of the silo or warehouse floor.
As this cold, dry air moves upward, it extracts heat and moisture from the grains, layer by layer, forming a “cooling front.” This front advances gradually until the entire bulk reaches uniform temperature. Intelligent control systems monitor air temperature, humidity, and grain sensors, automatically adjusting the cooling process for maximum efficiency. Once the grain reaches its target temperature, the unit switches to standby, maintaining equilibrium with minimal energy use.
The design principle behind Grain Vault is non-invasive precision. Unlike traditional aeration systems that depend on ambient weather, Svalz operates independently of outside climate. Even under tropical heat or monsoon humidity, it delivers stable, repeatable results. The system’s compressor, electronic expansion valve, and EC fan technology ensure maximum performance with minimal power consumption — a perfect harmony of physics and engineering.
