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.

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.

Frequently Asked Questions

What is a pressure vessel?

A pressure vessel is a container designed to safely store hot liquids, vapors or gases at high pressure levels. Notable examples of pressure vessels are boilers, heat-exchangers and storage tanks.

A ruptured or otherwise damaged pressure vessel can be extremely dangerous, or even explode. That is why pressure vessel manufacture is strongly regulated.

Letina pressure vessels are made in accordance with the strict European PED Legislation. Our tanks go through rigorous inspection and testing.

What does CE PED mean?

PED stands for Pressure Equipment Directive – a set of European legislation that govern design, manufacturing, inspection and testing of pressure equipment.

A product bearing the CE PED mark symbolizes the product is certified and safe to use.

You can check out our PED certificate here.

What is the Charmat method?

The Charmat method is a way of making sparkling wine by trapping bubbles in wine by carbonating them in large, stainless steel tanks. That is why it’s often referred to as the “Tank method”.

Also known as metodo Italiano, cuvée close and autoclave, it has made the process of making sparkling wines more affordable and is revered around the world. It is the main method used for making Prosecco and Lambrusco wines.
