Control System. Highest efficiency and maximum user-friendliness.

The informative and clear MIXACO process visualization on the control panel ensures safe and reliable operation of the entire heating-cooling mixer combination.

The control of our heating-cooling mixer combinations is based on a Siemens S7-1500 PLC and meets today’s requirements for safety, efficiency and economy.

The development and programming of the control system from a single source ensures optimum integration of the mixer components.

Alternatively, it is also possible to use components from Allen Bradley (incl. Panelview operating unit) or to design the control system in accordance with UL/NEMA.

In addition, the control can be equipped with an interface for data exchange to a higher-level control system.

A Siemens TP1200 operating panel (12″ color display with touch operation and Ethernet interface) is used for operation and process visualization. On the basis of the operating panels, a function-oriented operation of the heating-cooling mixer combination in manual or automatic mode is possible.

The mixing parameters are entered in a special recipe management system. Parameters such as circumferential speed, dehumidification, discharge, liquid injection, double batching and much more can be activated and defined.

The recipes are stored in a directory for later use. Optionally, the control can be equipped with integrated remote maintenance.

  • etc.

PVC Heating / Cooling Mixer horizontal and vertical. Heating and cooling to the exact temperature.

Outstanding PVC Mixing Technology

With our combined heating-­cooling mixers, PVC compounds are precisely heated and then highly efficiently cooled. The horizontal design of the PVC heating-cooling mixer was developed for large throughputs, fast processing and 100% reliability.

Our heating mixers, cooling mixers and combined heating-cooling mixers are suitable for mixing and processing PVC raw materials like no other industrial ­mixer.

PVC Heating Mixer. Perfect Dispersion.

Optimal dispersion of PVC powder with powders, granulates or liquids

The new HM series of heating mixers offers the optimal solution for all applications where dispersion of powders with powders or granules with or without liquid addition is required. The possible applications are manifold.


  • Dry blends of rigid and soft PVC
  • WPC (Wood-Plastic-Composites based on PVC / PP / PE with wood flour content)
  • Thermoplastic polymers (PVH, PVA, PC, POM etc.)
  • Hot or cold dispersion of color masterbatch, additives and powders
  • Premixing of powder coatings
  • Powder coatings / bonding with metallic pigments or mica
  • And much more

PVC Cooling Mixer Horizontal. High efficiency cooling without agglomeration.

The new high-efficiency KM H horizontal cooling mixers are optimized for maximum performance in cooling hot dry blends from the turbomixer.

Thanks to the large surface of the heat exchange area (tank, sides and lid) and the intensive contact of the dry mix with the exchange surface by the main agitator, KM H cooling mixers allow the lowest possible final cooling temperature.

This allows the dry blends to be stored in intermediate ­silos, which counteracts the formation of lumps due to the thermal inertia of the dry blend.

All surfaces that come in contact with the product are made of highly polished stainless steel for easy cleaning and to prevent material buildup.

PVC Cooling Mixer Vertical. High efficiency cooling without agglomeration for smaller batch sizes.

The KM V vertical cooling mixers have been developed to provide econom­ic and reliable solutions for throughputs up to 3,000 kg / h.

In the vertical cooling mixer, cooling of the mix takes place by gentle material circulation on a cooled surface.

A targeted water supply in the mixer bottom and side wall ensures optimum cooling performance of the mix. After completion of the mixing process, the cooled mix is quickly discharged via the contour-shaped outlet.

Filter / Aspiration

Dehumidification of the mixture by means of aspiration is crucial for the optimum quality of dry blends. A constant air flow transports the moisture out of the heating mixer to avoid buildup in the mixer.


Jet-Filter / Aspiration

Bag Filter Box


Depending on the design, our mixers can be used in potentially explosive dust and gas atmospheres of all ATEX zones by nitrogen inerting or oxygen concentration measurement. A machine acceptance is carried out and documented by an official inspection body or an appropriately certified employee.

Remote Maintenance

The remote maintenance module provides the possibility to access the control of the heating/cooling mixer combinations quickly and securely via a VPN tunnel. This enables our service team to diagnose and rectify faults without having to be on site. This makes data recording and evaluation possible.
