Reservoir Vent Dryers


Reservoir Vent Dryers are designed to protect storage drums and tanks during operation. As the fluid is drawn from the reservoir or air above, fluid is displaced by temperature variations. The air entering the reservoir goes through an active bed of desiccant that functions to remove and retain water vapour.

Fast and easy to install, the vent dryer is fitted with a moisture absorbing desiccant known as Envirogel or Orange-indicating Silica Gel. When this desiccant becomes saturated by water, it provides a visual alert to users through its colour change from orange to green, indicating the need for replacement.

This product is best suited for companies which have storage drums, reservoirs and tanks as it requires no energy and provides continuous protection for your items. The vent dryer is capable of preventing your fluids from absorbing water vapour and condensing. Once your fluid condensates, physical and chemical changes would take place, making it unusable. Field tests have also shown that when the Reservoir Vent Dryers are installed, the airspace above is safe from condensation within the first few hours.

Protect small storage tanks, reservoirs and drums with reservoir vent dryers

The use of reservoir vent dryers does not require power input and 24/7 protection to the fluids or items stored within the reservoir. Condensation in the fluid produces permanent chemical and physical changes. These devices prevent fluids contained in the tank or drum from absorbing moisture, vapours, and condensation.

Reservoir vent dryers are rechargeable with a simple installation while providing constant protection while minimizing pressure differences. These dryers can be filled with silica gel, molecular sieves, activated carbon that help in flame suppression and reduce odour emission.

Here in Streampeak we offer a wide variety of Desiccant Breather solutions to protect your equipment from moisture damage and contamination. Moisture Absorbers, known as Desiccants and Humidity Indicator Cards which are used to ensure that moisture-absorbing measures work are also available.
