Square Tank

The square tank was designed to better adapt to modern cellars. Thanks to its rectangular shape, it neatly fits into corners and along straight walls.

Placing the square tanks next to each other you gain cellar space that would otherwise be wasted due to the circular shape of other tanks.

Stack multiple square tanks on top of each other to make best use of all the available space.

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

Thanks to the vertical construction of the cooling jacket, the stored liquids will be efficiently chilled even if the tank is not full to the brim.

AISI 304

The square 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 square tank. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Rectangular Shape

The rectangular shape of our square tanks allows you to place them closer to each other, maximizing the used space in your cellar. They will also naturally fit into corners.

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.

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.
