Stainless Steel
Closed Tank

This stainless steel storage tank is one of the oldest models in Letina’s lineup. Tried and tested throughout the years, it has proven its versatility and value time and time again.

Thanks to constant design improvements, the closed tank got better over the years – just like the wine it’s designed to contain.

Whether you want a simple storage tank, a fermentation tank, something to age your product in or even a mixing vessel – this closed top tank can do it all.

large, dimpled jacket makes sure the temperature inside the sealed tank is always optimal. Thanks to the vertical construction of the cooling jacket, the stored liquids will be efficiently chilled even if the closed tank is not full to the brim.

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

AISI 304

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

Marbled Finish

A high-polish, marbled finish is applied to the outside of the closed tank. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Dimple Jacket

A dimple jacket is a thin, spotted shell that regulates tank temperatures with the help of a cooling/heating medium such as glycol. They are made of light-weight materials and spot-welded for minimal additional weight.

Stacking Technology

Make smart use of your limited cellar space by stacking tanks on top of each other. Stacking allows you to reorganize your production line and make it more efficient than ever.

Wheels*

This tank can be equipped with wheels, making it easier than ever to get into place. *Some size restrictions apply.

Forklift Skirt*

The tank can be equipped with 2 slots for a lifting fork that enables easy maneuvering around the cellar with a forklift. *Some size restrictions apply.
