Closed-Storey Tank

ZK Tank

The Letina ZK closed storey tank consists of two or more chambers and is used for the fermentation and storage of wine and other alimentary liquids. The ZK is a more compact alternative to the standard Z tank and is ideal for manufacturers needing to optimise available space in their production facility. It is constructed of high-quality materials and is easy to clean. The high polish ensures scale does not develop.

As standard, tanks are supplied with cooling jackets, temperature gauge, manway door, pressure valves, total drainage port and sample tap.

Sizes range from 500 litres to 40,000 litres.
