A blanketing regulator is a self-operated pressure control device designed to maintain a constant low-pressure inert gas (typically nitrogen) blanket over stored liquids. It protects tanks from air ingress, moisture contamination, and explosion hazards while minimizing product loss.
This helps prevent outside air, moisture, and contaminants from entering the tank, protecting the stored product from oxidation, spoilage, or chemical reaction. It also reduces evaporation losses and lowers the risk of fire or explosion when handling flammable liquids. Blanketing regulators are commonly used in chemical plants, oil storage facilities, pharmaceutical industries, food processing plants, and other applications where product quality and tank safety are important. Since they operate without external power, they are reliable, economical, and easy to maintain.
