Cylindrical Conical Tank (CCT)
In beer production, cylindrically conical fermentation tanks play a crucial role, particularly in the fermentation process. These tanks are often manufactured from high-density polyethylene (HDPE), ensuring durability and resistance to corrosion.
A typical 200l pressure tank features a conical bottom, allowing for efficient complete drainage of sludge after the primary fermentation. The top cone of the tank facilitates the maturation of the beer, ensuring optimal conditions for the fermentation of beer and subsequent maturation of the tank contents.
These cone-bottom tanks are versatile and suitable for both indoor and outdoor applications. Cone fermentors are designed to withstand overpressure and are equipped with a relief valve to maintain safety.
The side of the tank often includes access points for monitoring the content of the tank and ensuring sanitary conditions throughout the fermentation process.
Conical tanks offer a streamlined approach to storage tanks, optimising both the fermentation and maturation phases essential for high-quality beer production.
Fermenters for Beer
CCT Tanks (Cylindrical Conical Tank)
Cylindrical conical fermentation tanks are mostly used for fermenting beer. Here, the yeast can settle in the cone at the end of fermentation and be easily separated from the young beer for clean phase separation during yeast harvesting.
For procedural reasons, an internal cone angle of 60-70° has been established. This also makes the tanks suitable for producing beer in the 1-tank process.
For fermentation tanks made of stainless steel, Gpi supports you in the selection of the suitable material and the optimal equipment. This way, we can deliver the right tank for your brewing process.
Design According to Customer Requirements
Like all tanks manufactured by Gpi, the cylindroconical fermentation tanks can also be customised for your specific requirements.
Our designs accommodate pressureless fermentation or main fermentation under counterpressure, with volumes aligned to your brew size and spatial constraints.
We recommend a minimum tank volume equal to one brew size, accounting for necessary rising space. Our team optimizes the tank’s diameter-to-height ratio to maximize available space in your fermentation cellar.
Our stainless steel fermentation tanks range from 50 hl to 5,000 hl in volume.
Production of Cylindroconical Fermentation Tanks
Our fermentation tanks feature a standard surface roughness of RA ≤ 0.8 µm. For processes requiring enhanced smoothness, we offer full grinding or electropolishing options, achieving a surface roughness of up to RA ≤ 0.5 µm. We utilize O-ring and seal materials tailored to your specific requirements.
Innovative Cooling Solutions To manage fermentation heat and precisely control temperature, our cylindroconical tanks can be equipped with multiple cooling zones or complete jacket cooling. We offer various cooling implementations:
- Thermoshelf design
- Half-pipe system
- Double jacket configuration
For optimal energy efficiency, we provide insulation options using PUR foam or insulating wool, minimizing heat loss during the cooling process.

Equipment
Cylindrical conical tanks made of stainless steel can be supplied with a manhole on request. This allows the tank to be cleaned manually. In addition, a spray ball can be included to integrate the tank into the CIP cleaning process.
Furthermore, Gpi tanks can be supplied with a nozzle for temperature measurement to control the cooling, as well as with nozzles for level control.
At the customer’s request, a flange for mounting a safety valve at the head of the fermentation tank can be designed.
Depending on the size of the fermentation tank and the installation situation in your brewery, the cylindroconical fermentation tanks are delivered on feet or with claws.
