Stainless Steel
Olive Oil Storage Tank

Olive oil is very sensitive. Many factors affect the quality of your oil – like air, light, heat, water, sediment. These speed up the oxidation process, shortening the shelf life of olive oil. It also likes to soak up nearby fragrances and flavors, which alter its taste and smell.

Stainless steel is the perfect material for olive oil storage. It has no flavor or odor, and is impenetrable by sun or moisture.

Letina [ZU] stainless steel tanks are designed specifically for olive oil storage and have several quality-of-life features aimed at the olive oil industry. Conical bottoms enable purging, special valves make racking easy, and the inert gas fitting prevents oxidation.

Durable, high-quality materials enable the olive oil storage tank to stay in pristine condition, even after years of professional usage.

AISI 304

The olive oil storage tank is made out of AISI 304 quality stainless steel. An upgrade to AISI 316L stainless steel is available for high-corrosion environments.

Mirror Polish

A high-polish, mirrored finish is applied to the outside of the conical fermenter. Marbled, Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) Mirror polished.

Conical Bottom

The olive oil storage tank tank comes with a centered conical bottom (30°/45°/60°) by default.

A special inert gas fitting is built into the tank that helps prevent oxidation.

Odorless

Stainless steel is completely sanitary and will not impart any taste or smell on your oil.
