Beverage & Oil Preservation

N₂ blanketing for edible oil tanks, wine bottling lines, and beer brewing vessels. Creates an oxygen-free headspace that preserves quality, flavor, and extends shelf life.

N₂ Blanketing

Why Nitrogen Blanketing?

Oxidation Prevention

N₂ blanket over the liquid surface prevents oxygen contact. Oils stay fresh 3× longer. Wine and beer maintain their intended flavor profile without off-flavors.

Bulk Storage Savings

Blanket large storage tanks (5,000–50,000 L) with continuous low-flow N₂. Cost per liter protected is minimal with on-site generation.

Product Consistency

No rancidity in edible oils. No oxidation off-flavors in beverages. Every bottle tastes the same — from first fill to last from the storage tank.

Reduced Additives

N₂ blanketing reduces or eliminates the need for antioxidants (BHA/BHT) in oils and sulfites in wine. Cleaner ingredient labels.

How It Works

1

N₂ Generation

PSA produces high-purity N₂

2

Buffer Storage

N₂ stored in buffer tank

3

Pressure Regulation

Low-pressure delivery (0.1–0.5 bar)

4

Headspace Purging

N₂ sweeps oxygen from headspace

5

Continuous Blanket

Low-flow N₂ maintains blanket

Common Applications

Edible Oils

Olive, vegetable, palm oil storage. Blanketing prevents rancidity during long-term storage.

Wine & Spirits

Bottling line inerting, barrel headspace. Reduces sulfite usage by 30–50%.

Brewing

Fermentation headspace, bright tank blanketing. Lower dissolved oxygen in finished beer.
