Continuous heating, crystallization, drying and coating of a wide variety of plastics and other bulk materials in minutes instead of hours.

Heating. Crystallization. Drying.

Field of applications.

Heating. Heating granules and regrind material prior to further processing (e.g. PVC, PE, PP,…) inter alia to improve the throughput in the extrusion.

Crystallization. Crystallisation of PET (Bottleflakes, granules, flakes), PET masterbatch, co-PET, PBT, PEEK, PLA, PPS, etc.

Drying. Drying of plastic granules, and –ground material (e.g. PET, PBT, ABS/PC, HDPE, LCP, PC, PP, PVB, WPC, TPE, TPU) as well as other free-flowing bulk materials.

Coating. Coating of adhesives (e.g. Hot melt, EVA+lime,…)

High input moisture. Drying processes with high input moisture >1%.

Diverse. Thermal processes for the removal of rest oligomeren and volatile components.


Function IRD.


Heat into the core. The energy is instantaneously brought into the core of the product by short-wave infrared radiation.

Inside to the outside. The heat flow pushes the moisture from the inside towards the outside of the product.

Discharge moisture. After the moisture has been released from the material it is directly discharged by the air circulation inside the machine.

Always in motion.

Rotation. The rotation of the drum ensures constant movement of the material.

Evenly. The spiral coils and mixing elements designed for your product ensure an optimal mix of material and avoids clumping. Your product is evenly heated.

Gently. Due to the low rotation speed of the drum there is no dispersion of the material.

Setting. Control.

Retention time. The retention time of the continuous IRD depends on the speed of the rotary drum.

Setting. This retention time, the radiator performance, as well as many other process parameters are regulated by means of integrated PLC control.

Control. The process data, such as material and exhaust air temperature or fill levels are continuously monitored by means of sensors and pyrometers. Deviations cause the automatic adjustment.

Reproducibility. Recipes and process parameters can be stored in the controlling system to ensure optimal and reproducible results.

Remote maintenance. Online service via modem.

Radiator module.

Optimized. Our radiator module developed for the IRD is thermal and fluidic optimized and is cooled by a continuous air flow.

Efficiency. A special ceramic ensures optimum utilization of infrared light.

Air-Shield. An air Shield protects the module against the ingress of dust particles and ensures fast removal of moisture escaping from the dry goods.



Ideal for continuous production. Production without interruption.

Filling. By means of volumetric dosing, the material to be processed is conveyed continuously through the rotating drum.

Conveying. Mixing. Thermal treatment. A spiral welded into the rotary drum ensures a mixture of material and continuous transfer to the outlet. The material is thus thermally treated continuously.

Outlet. In minutes instead of hours, the material automatically leaves the rotary drum and can be transferred directly to the next processing step.

Advantages for your process.

Low energy consumption. Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product.

Minutes instead hours. The product remains for only a few minutes in drying process and is then available for further production steps.

Instantly. An immediate start of the production run is possible immediately upon startup. A warm-up phase of the machine is not required.

High efficiency. The energy is immediately brought into the core of the product.

Gently. The material is gently from the inside to the outside heated and not loaded from the outside for hours with heat / damaged.

Easy. Good access to all components allows for easy and fast cleaning. Rapid product change-over.

In one step. Crystallization and drying in one step.

Increase throughput. Increase of throughput of the plant through relief of the extruder.

Evenly. Ensuring a constant discharge.
