Open top fermentation tank PZP Letina

Variable-capacity tanks have recently become a staple of the wine industry. They offer complete control over the fermentation process to small and growing wineries. Even though their yields depend on the annual harvest, they can use the same tank every year.

Thanks to the “floating” lid, you don’t have to fill the variable capacity tank to its brim. The inflatable gasket achieves an air-tight seal, preventing accidental oxygen contamination.

Moving the floating lid into place and securing the air seal is easy with the mounted lifting arm and stainless steel hand pump. Durable, high-quality materials enable the variable capacity 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.
