The horizontal cooling HC mixer is used for efficient cooling of bulk materials in the plastics and chemical industries. The double jacket in a state-of-the-art pillow plate design is pressure-resistant up to a maximum of 7 bar. A turbulent water flow guarantees optimum heat transfer and fast, effective cooling of the bulk material.
The mixing tools also enable high mixing performance, which is crucial when adding further components (e.g., during double batching) to the cooling mixer.
In combination with a high-intensity mixer, it has proven itself in various applications such as: PVC dry blend, compounding, WPC, etc.
Key advantages at a glance

In plastics processing, cooling mixers are used after hot mixing to bring the heated material to processing temperature quickly and in a controlled manner. This prevents thermal damage and optimally prepares the mixed material for further processing.

In the chemical industry, cooling mixers control exothermic reactions and gently cool sensitive substances after mixing. This not only improves product stability, but also significantly increases process safety.

Good accessibility for cleaning and maintenance purposes.

Discharge plate adapted to the inner contour of the bowl.

The mixer control system features an intuitive user interface that makes it easy to operate in both manual and automated modes.
