Letina - Model Z -Stainless Steel Closed Tank
Thisstainless steel storage tankis one of the oldest models in Letina’s lineup. Tried and tested throughout the years,it has proven its versatility and valuetime and time again.
Thanks toconstant design improvements, the closed tank got better over the years – just like the wine it’s designed to contain.
Whether you want asimple storage tank, a fermentation tank, something to age your product in or even a mixing vessel– this closed top tank can do it all.
Alarge, dimpled jacketmakes sure the temperature inside the sealed tank is always optimal. Thanks to the vertical construction of the cooling jacket, the stored liquids will beefficiently chilled even if the closed tank is not fullto 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.
Conical Eccentric Bottom
The closed tank comes with a conical eccentric press-molded bottom by default. Large tanks come with a centered bottom to keep discharge easy.
Conical Eccentric Top
A press-molded eccentric conical top comes standard with all closed storage tanks. Other head shapes are available upon request.
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.
