Heinrich Frings GmbH & Co. KG products

The FRINGS PROREACT B fermenters for sterile sensitive industrial production procedures with working volumes of several 10,000 litres and also as large-scale fermentation systems of greater than 100,000 litres are designed, produced and commissioned for specific projects.

PROREACT B fermenters are used in the laboratories and technology centres of industrial companies for the research, process development and scaling-up. In production, these units are used as seed levels for the sterile cultivation of the micro-organisms within a fermenter production line.

In comparison with the PROREACT B series, PROREACT P bioreactors are the even higher quality design. These systems satisfy the absolute top requirements of “hygienic design”, the component and material properties and fermenter equipment. In addition, in the control part, there are extended programme structures, safety devices and special sequences and regulations to safely and efficiently design the manufacture of expensive products.

PROREACT P laboratory and pilot fermenters are manufactured in standard sizes from 10 litres and are used both for research and development as well as the preliminary stages within a production fermenter cascade of ascending size.

Through the special properties of the PROREACT C reactors with the integrated FRIBORATOR C turbines, very high mass transfer coefficients with low energy consumptions can be realised. A fact that is becoming more and more important in times of high energy prices and when taking into account the demand for resource-friendly production procedures.

CLEARFLOW C filtration systems can be used in a number of sectors where no hygiene criteria must be applied. These systems are designed especially for industries which require particularly easy-to-operate and resistant systems. Chemical-resistant finishes and robust units are the different equipment specifications of these systems. 

CLEARFLOW P filtration systems in “hygienic design” are used in sensitive fields of biotechnology and food industry. Depending on the application, the filtration systems are designed especially with respect to the characteristic of the medium and the risk of contamination and fouling. Particularly when determining the filtration modules, all rheological and dynamic conditions of the medium being filtered are taken into account.

Foams occur in many processes, e.g. through a medium being aerated, through reaction gases being released or through gas being discharged from a medium into a vacuum. Often, it is necessary to control the amount of foam to prevent equipment downstream, such as filters or pumps, from becoming contaminated. With the help of the mechanical FOAMEX foam centrifuge, foam control can be achieved in most cases without chemical defoaming agents being added. This often not only results in benefits in the foaming process, but also when overhauling or further processing the antifoam-free media.
