The “Wineficator” is a pump-over fermenter designed to make remontage easy.

The HELI rotating sprinkler evenly soaks the pomace cap in the tank, while a built-in sieve separates the solid substance from the liquid.

Several options are available to fully automate the entire process:

  • Pneumatic devices send bubbles from the bottom of the tank, delicately agitating and mixing the liquid.
  • Rotating paddles at the bottom of the pump-over wine fermentation tank are activated to fully unload the pomace from the vessel.
  • A programmable, touchscreen control panel serves as a temperature and pump regulator.


The large, dimpled jacket makes sure the temperature inside the pump-over fermenter is always optimal. 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.

Durable, high-quality materials enable the wine fermentation tank to stay in pristine condition, even after years of professional usage.

AISI 304

The pump-over fermenter 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 pump-over fermentation tank. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Sloped Bottom

The pump-over wine fermentation tank comes with a flat, sloped bottom. Paired with the large, rectangular door, the discharge of the sloped tank is made easy.

Conical Eccentric Top

A press-molded eccentric conical head comes standard with all pump-over fermenters. Other head shapes are available upon request.

Rotating Sprinkler

The rotating HELI sprinkler is mounted on the pump-over fermenter's head. It efficiently soaks the entire layer of pomace in the wine tank.

Impulse Mixing

Pneumatic devices are located on the bottom of the tank. They send short bursts of air, creating bubbles. The bubbles rise to the top, delicately mixing the liquid in the vessel.

Pomace Discharge

The rotating blades mounted to the bottom of the wine fermentation tank gently push the leftover pomace out of the rectangular doors, automatizing discharge.

Control Panel

The pump-over wine fermentation tank comes with a programmable, touchscreen control panel. It regulates the pump and temperature inside the tank, allowing you to automatize the entire process.

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.
