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.
A 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.
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.
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.
The closed tank comes with a conical eccentric press-molded bottom by default. Large tanks come with a centered bottom to keep discharge easy.
A press-molded eccentric conical top comes standard with all closed storage tanks. Other head shapes are available upon request.
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.
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.

A closed tank, also referred to as a sealed tank or closed top tank, is any fixed capacity storage vessel. The top of this type of tanks is sealed by welding it to the body, hence the name sealed tank.
The opposite to a closed tank is a variable capacity tank.
The closed tank is a completely sanitary vessel made out of AISI 304 stainless steel. It is suitable as a storage tank for a wide variety of liquids and foodstuffs. Wine, beer, liquor, dairy, confectionery, cosmetics, pharmaceuticals – even corrosive chemicals can be stored in the closed tank with an upgrade to AISI 316L stainless steel.
Learn more about the different properties of AISI 304 and AISI 316 stainless steels.
The closed tank was initially designed for the wine industry and intended as a storage and fermentation vessel. Since then, it received many design upgrades. Now, the closed tank is suitable for storage, fermentation and mixing of any sanitary liquid or powder.
You receive our quote and decide whether you want to change it. If you're satisfied, we move onto the design and engineering phase.
You give us inputs based on the drawings we send you. It is an iterative process and we only stop when you're 100% satisfied.
You sign the final version of the drawing and email it to us. We then schedule the tank for manufacture. You still have some time for making small changes.
Your final tank design enters the production line. It is assembled from high-grade stainless steel using advanced welding techniques.
Your tank is shipped out to you, including a manual and proper maintenance guide. We'll always be there for you to provide assistance.
