engineered for efficiency, built to last
The installation of a desiccant dehumidifier in the base of the silo skirt is the simplest, most cost effective solution. The dehumidified fresh air can be ducted to the head space through either the fill line or via a dedicated dehumidified air line, this causes a slight overpressure in the silo head, with excess air discharged via the vent filter assembly, ensuring that air in the head space is maintained at a low relative humidity.
*It is important to note that the desiccant dehumidifier must be isolated during filling to avoid damage.
In some cases a recirculation system maybe required to achieve very low humidity levels, an example being PLA (Polylactic Acid). In this scenario additional filtration is required to avoid potential damage to the dehumidifier.
