Storage and Fermentation 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.
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.
