Stainless Steel
Variable Capacity Tank
(Sloped Bottom)

Designed for processing red wine, the PZPK variable capacity tank comes standard with a sloped bottom and a big square door. It is intended for professional use.

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.

AISI 304

The variable capacity tank is made out of AISI 304 quality stainless steel. An upgrade to AISI 316L stainless steel is available for high-corrosion environments.

Marbled Finish

A high-polish, marbled finish is applied to the outside of the sloped tank. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Sloped Bottom

This variable volume tank variant comes with a flat, sloped bottom. Paired with the large, rectangular door, the discharge of the sloped tank is made easy.

Floating Lid

The variable capacity tank exists thanks to the "floating" lid that is placed just above the level of the liquid inside of the tank. An air-tight seal is achieved by inflating the gasket.

Variable Capacity

The floating lid can achieve an air-tight seal at any volume - making the variable capacity tank the perfect fit for small and growing wineries.

Lifting Arm

Maneuvering the floating lid is easy thanks to the built-in lifting arm. A hand-operated winch is available as an option to make it even easier.

Sloped Bottom

The PZPK variant of the variable capacity tank comes standard with a sloped bottom and a big square door, designed to ensure an easy discharge of the tank.

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.


This tank can be equipped with wheels, making it easier than ever to get into place. *Some size restrictions apply.

Forklift Skirt*

The tank can be equipped with 2 slots for a lifting fork that enables easy maneuvering around the cellar with a forklift. *Some size restrictions apply.
