Due to the increase in viscosity caused during cooling, the fluids to be cooled tend to adhere and form deposits on the cooling surfaces. This leads to long residence times and product degradation (fouling). Since the introduction of Promix P1 cooling mixer technology, these problems are a thing of the past. The cooling mixer technology, which was developed using state-of-the-art CFD methods, is now being used in more and more areas of application.

The technology, which was originally developed for plastics processing, is now also being used successfully in fiber and polymer production, chemical, pharmaceutical, and food production. In addition to cooling, the technology is also well suited for heating fluids that are residence time critical and sensitive to decomposition.

The Promix P1 cooling mixer is the unique combination of a very efficient static mixer and a powerful cooler. The novel patented technology opens up completely new process engineering possibilities when cooling plastic melts and other viscous fluids. The simultaneous mixing and cooling processes in the P1 allow very efficient cooling close to the solidification point

of the melt without the formation of deposits or the risk of "freezing". The melt temperature is simultaneously homogenized over the entire cross-section. Depending on the process step, the ideal melt temperature can thus be precisely set and kept constant over time.
