Charmat Pressure Tank
Charmat Pressure Tank
The Charmat Tank is a high-performance stainless steel pressure vessel engineered specifically for the secondary fermentation and production of sparkling wines. Built to safely withstand a working pressure of 6 bar, this tank is the ultimate solution for winemakers utilizing the Charmat (Italian) method to produce fresh, aromatic sparkling wines like Prosecco.
Constructed from premium AISI 304 stainless steel (with an available upgrade to AISI 316L for high-corrosion environments), the vessel features a highly sanitary, mirror-polished BA (IIId) interior. To ensure maximum energy efficiency, the tank is wrapped in a thick, dense layer of polyurethane (PU) foam insulation, keeping your cooling costs low even during the most demanding temperature holds.
6-Bar Work Pressure: Engineered to handle the intense pressures required for secondary fermentation and natural carbonation.
DIN 28013 Ellipsoidal Heads: Both the top and bottom feature specialized semi-ellipsoidal heads compliant with strict German engineering norms to safely distribute high internal pressures.
Dual-Zone Dimpled Jacket: The vertical construction of the cooling jacket ensures that the liquid is chilled efficiently, even during partial fills or small-batch production.
PED Certified Access: Can be equipped with specialized, pressure-rated PED manhole covers and manway doors for safe operation and effortless cleaning.

Frequently Asked Questions
What makes the Charmat Method different from the Traditional Method?
In the traditional method (Champagne), secondary fermentation happens in individual bottles. In the Charmat Method, the secondary fermentation takes place on a large scale inside our 6-bar pressure tanks. This allows winemakers to produce high volumes of sparkling wine much faster, while perfectly preserving the fresh, fruity, and floral characteristics of the base grape.
Why are the ellipsoidal top and bottom compliant with DIN 28013?
When dealing with 6 bars of pressure, the geometry of the tank is a matter of safety. Flat or standard dished bottoms can warp or fail under that much force. The DIN 28013 semi-ellipsoidal shape is the industrial gold standard. Its mathematically optimized curve perfectly distributes internal stress, ensuring the tank remains structurally flawless after years of heavy cycling.
How does the PU insulation and dimpled jacket save money?
Sparkling wine production requires strict temperature management to control yeast activity and preserve delicate aromas. The combination of a thick polyurethane (PU) foam wrap and high-efficiency dimpled cooling jackets creates an impenetrable thermal barrier. This means your glycol system doesn’t have to work overtime to keep the tank cold, drastically reducing your monthly energy bills.
Can I use this tank for beverages other than sparkling wine?
Absolutely. While designed for the Charmat wine method, a 6-bar pressure vessel is incredibly versatile. It is a premium option for force-carbonating cider, conditioning high-pressure beers, or storing and carbonating ready-to-drink (RTD) craft cocktails on a commercial scale.
Is the tank easy to clean between batches?
Yes. The interior of every Letina Charmat tank features a pristine BA (IIId) mirror-polished finish. This ultra-smooth surface prevents wine stone (tartrates) and yeast from gripping the steel, making your CIP (Clean-in-Place) cycles faster, using less water and fewer chemicals.
