Stainless Steel
Charmat Tank

The Charmat Tank is a stainless steel pressure vessel designed for sparkling wine production using the Charmat method at a work pressure of 6 bar. It has a dished top and bottom and can be equipped with special, PED manhole covers and manway doors.

The pressure vessel is wrapped in a thick layer of PU foam, insulating it and ensuring minimum energy consumption.

A large, dimpled jacket makes sure the temperature inside the pressure vessel is always optimal. Thanks to the vertical construction of the cooling jacket, the stored liquids will be efficiently chilled even if the Charmat tank is not full to the brim.

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

AISI 304

The pressure vessel 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 Charmat tank. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Ellipsoidal Bottom

The pressure tank is equipped with a semi-ellipsoidal bottom. It can withstand the high pressures building up inside the tank. It's compliant with the DIN 28013 norm.

Ellipsoidal Top

A rounded, semi-ellipsoidal head is standard for the Charmat tank. It is specially shaped to handle work under high pressures and compliant with the DIN 28013 norm.

Pressure Vessel

The Charmat tank is designed, manufactured, inspected and tested to safely perform at high pressure levels. Our CE PED certificate ensures maximum quality and safe use.

Insulation Layer

The pressure tank is wrapped with a thick layer of polyurethane foam which provides great thermal insulation. The PU foam is resistant to moisture and water, making it perfect for stainless steel tanks.

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.
