Tank Vent Dryers

Eliminate moisture problems from your vented closed system storage tanks.

Storage tanks are commonly used to hold stocks of bulk material for a wide range of products. Often these stored materials may be hygroscopic or sensitive to moisture. Any storage tank typically comes equipped with vent pipes, filter caps, or turn down pipes to prevent contaminants from entering the tanks. Though these may help to filter out particulates, they are not efficient in removing the most damaging contaminant, which is water, especially in vapour form.

To ensure full protection from moisture damage and to avoid degradation of the stored material, AFE has specially designed the AFE Tank Vent Dryer to serve as your first line of defence against moisture contamination.
