Three phases with the highest selectivityThe efficient 3-phase decanter centrifuge
In the classic separation process, solids are separated from a liquid, or two liquids of different densities are separated. But often both come together. This is exactly where the Tricanter® from Flottweg is the right solution. It allows the continuous separation of three phases (solid-liquid-liquid) in a single process. This is attractive, for example, in the treatment of oily sludges, in starch production and in fat recovery.
More than 40 years ago, Flottweg developed the Tricanter® to separate three phases in a single simultaneous process. The prerequisites for this are that the liquids are not soluble in each other, that they have different densities and that the solids phase has the highest specific weight. On this basis, the specially designed impeller system produces optimum separation results.
Three-phase separation offers users several advantages: The combination of the processing steps eliminates the need for additional separation stages, which results in considerable cost savings. In addition to its high selectivity, the Tricanter® is particularly attractive because of its versatility. It can adapt to changing inlet conditions at any time. In addition, there are the proven engineering and Flottweg services, from application-oriented project planning, through commissioning, to maintenance and spare parts supply. Thus, users benefit in the long term from the highest quality "Made in Germany."Get guidance now
The application range of the 3-phase centrifuge
How the Flottweg Tricanter® works
The design and function of the Flottweg 3-phase centrifuge is similar to that of a decanter (two-phase separation). Solids settle on the inner wall of the bowl when subjected to centrifugal force. The scroll constitutes the conveying tool. Under centrifugal force, solids settle on the inner wall of the bowl.
The decisive difference to the decanter lies in the separate expulsion of the two liquid phases: With the Tricanter®, the heavy liquid is discharged under pressure via an adjustable impeller. The light liquid flows off without pressure. The impeller allows infinite adjustment of the pond depth during operation and thus fast, precise adaptation to changing feed conditions - without interrupting operation.
The Tricanter® guarantees a high level of economic efficiency, because the continuous three-phase separation eliminates the need for further processing steps and separation stages. The particular strength of the Flottweg Tricanter® is demonstrated by the highest possible purity of the liquid phases to be separated through the use of the impeller. The separation process can be adapted at any time to changing conditions (product in the inlet). Individually manufactured decanter scrolls ensure the best separation results. In addition, Flottweg decanter bowls have application-optimized geometries. Tricanter® is manufactured exclusively in Germany to the highest quality standards.

- highest possible purity of the phases to be separated due to the adjustable impeller
- flexible adaption to changing inlet conditions
- individually manufactured decanter scrolls
- decanter bowls with application-optimized geometries
Safety and security
The safety of the Tricanter® is a central theme because of its high speeds, its continuous operation and its diverse fields of application. Flottweg offers maximum process reliability thanks to application-oriented wear protection, medium-based material selection, machine configuration and worldwide service. High machine safety is also guaranteed, as machines are designed according to current guidelines and monitored by various sensors and evaluation systems (e.g. vibration). In the case of flammable mixtures, explosion protection in accordance with the ATEX directive and current standards is also provided.
- application-related wear protection
- medium-based material selection and machine configuration
- worldwide service
- monitoring by sensors and evaluation systems
- explosion protection according to ATEX directive
Hygiene requirements are very high, especially in food processing - a central field of application for the Tricanter®. Flottweg designs and manufactures its centrifuges consistently in accordance with "Hygienic Design." In the food industry, all components in contact with the product are CIP capable (Cleaning in Place) and therefore designed for automated washing.
- construction according to the principles of Hygienic Design
- CIP cleaning (Cleaning in Place)
Flottweg Tricanter® are particularly easy to operate and maintain due to their application-optimized and compact design. An automated process is possible with impeller adjustment via an actuator. In addition, the intuitive InGo user interface makes control very easy. InGo simplifies and accelerates the sometimes highly complex processes involved in centrifugation. The operating concept is available for all Flottweg Tricanter®.
- easy to maintain due to compact design
- Adjustable impeller
- optimized control through InGo operating concept
The Flottweg 3-phase decanter centrifuge - two machines in one
Süpro GmbH from Lampertheim-Hüttenfeld in southern Hessen recycles around 40,000 tons of animal by-products annually. For the processing of fats, the company initially used a decanter and a downstream separator.
Then they decided to switch to a single Tricanter®, with success, as the video shows.
