Application areas

Plastics industry
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.

Chemical industry
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.
