Stainless Steel
Variable Capacity Tank

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.

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 variable capacity. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Conical Eccentric Bottom

This variable volume tank comes with a conical eccentric press-molded bottom by default. Large tanks come with a centered bottom to keep discharge 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.

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.

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.

Wheels*

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.
