In addition, through its Hyper Flow turbocompressor, it can help to raise energy efficiency. A 1,200 mc/h generator with side channel pumps in continuous operation consumes 16.5 kW/h, while a Hyper Flow – for the same performance – consumes 4.8 kW/h, it says, to deliver energy savings of more than 11 kW/h and annual cost savings above €35,000. Overall, the company had a 400 sq m stand with more than 50 machines on display at Plast.


Joint technology Kubota Brabender Technologie has unveiled its first joint product develop- ment – the enhanced NX Series feeder – at the recent Powtech show in Germany. The company was formed last year when


Kubota of Japan bought Brabender Tech- nologie of Germany. The NX Series feeder handles poor-flowing,


sticky powders as well as fibres and pellets. The feeder features a special negative angle wall hopper geometry and a diagonal agitator that prevents bridging and ensures optimal bulk material flow into the screw. In combination with other components, mass flow is optimised and a uniform screw fill level is achieved. The company showcased other products at

“Our ambition is to harness the synergies of both companies and jointly develop high-quality products for the global market,” said Bruno Dautzenberg, managing director of Kubota Brabender Technologie.


Common control Conair has implemented a common control across all its HMI-interfaced ancillaries – by adding a system for its dryers and drying equipment. Users can equip many of


Conair’s drying products with a control platform whose interface shares the same interactions and features as other Conair


ancillaries, such as desiccant dryers and hopper temperature controllers. 12 PIPE & PROFILE EXTRUSION | October 2023


“Introducing the DC-B Common


Control across our drying product line represents an effort to create an identical user experience across virtually all of Conair’s upstream auxiliary equipment,” said AJ Zambanini, drying products man- ager at Conair.


Its dryer customers now have a


control system that offers the same interaction style for throughputs above 15 lbs/hr, he added. “The same control interface is


already available in our blending, conveying, and temperature control auxiliaries, so there’s much less


training involved for an operator to understand and master the use of


different equipment.” Since introducing the platform into dryers, it has added three new features.


The first is an automatic Airflow Monitor, which electronically measures the total airflow quantity (cfm) in all drying equip- ment – complementing automatic dewpoint monitoring – to ensure that the quality and quantity of drying airflow is correct. Secondly, it has ‘setback on’ input. Ordinarily, temperature setback is automatically triggered over a period of hours. The new feature allows the system to reduce to a standby temperature based on machine downtime. This gives the user an additional level of control and provides energy-saving and material overdry protection automatically. Finally, it has self-adapt- ing ‘smart’ recipes: the DC-B control offers 20 standard recipes and can store up to 3,000 produc- tion recipes overall.


Dried out Koch Technik exhibited a number of its dryers at K2022.


With its mobile KKT dry air dryers, hygroscopic


granules can be dried directly next to the process- ing machine. Depending on the model, 55-100m³ of dehumidified air per hour is passed through the drying container and the moisture of the granules is absorbed. The saturated drying air flows over two alternat- ing desiccant tanks, where it is dehumidified again. This produces deeply dried air with a dew point of around -35°C – corresponding to a value of 0.19 g


H2O per m³ of dry air. In addition, its Eko-N series encompasses nine


models, with dry air volumes of 110-2000 m³/h. These offer up to 50% energy saving at constant
