Inoex launched its iXact system at K2019, which makes 16,000 measurements every second to determine pipe diameter with high accuracy.

Using semiconductor sensor technology and high-power LEDs, it can measure strongly vibrating tubes thanks to the high measuring sequence frequency. The high-power LED make measurement of most transparent materials very simple. As a ‘plug & play’ solution, it does not need any calibration and offers a difference function which registers any sudden variations. It can detect irregularities such as knots and necking on the measured extruded surface. An extra camera helps to compensate measur-

ing errors due to inclination. This increases the accuracy of the diameter measurement. The two- or three-axis measurement operates at high speed and with a high precision – and is available in three different versions: for small-diam- eter products; for diameters up to 30mm; and for diameters up to 120mm. The robust design ensures that knocks or

temperature changes do not have any effect on measuring results. At the same time, Inoex launched its iXray

system, which measures both wall thickness and diameter – for both mono- and multi-layer pipe – in the micron range. More details on this can be found in the ‘Multi-layer pipe’ feature on page XX. Other products on show at K2019 included: Warp

XXL, which can measure the dimensions of pipes up to 3,500mm in diameter and is based on radar technology; Quantum 360, which uses terahertz technology; and Aurex, which uses ultrasonics. �

Inovyn has developed its latest generation of PVC under the brand name Biovyn – as it is derived from sustainable materials. Made at its Rheinberg plant in Germany, Biovyn is made using ‘bio-attributed ethylene’ – a renewable feedstock derived from biomass that does not com- pete with the food chain. It is certified by by the

Roundtable on Sustainable Biomaterials (RSB) as delivering a 100% substitution of fossil feedstock

in its production system, enabling a greenhouse gas saving of over 90% compared to convention- ally produced PVC, says the company. “Through our sustainability programme we are developing a new generation of PVC grades that meet both the rigorous product quality and performance needs of our customers, whilst moving us closer towards a circular, carbon-neutral economy for PVC,” said Filipe Constant, business director of Inovyn. “There is growing demand for a specialist, renewable PVC that decouples its production from the conventional use of virgin fossil feedstocks.” The material is expected to have many applica-

tions across a range of industry sectors, including specialised end-uses such as automotive and medical. �

Koch-Technik introduced a new type of dry air dryer – under the name of Ekon – at K2019. The company has combined the advantages of

its CKT and Eko drying concepts into the new dryer. Ekon is available in eight sizes, with outputs ranging from 110 to 2,000 m³/h. The concept of a heat exchanger with piping system – taken from the Eko dryers – has been improved in new series. As the heat is recovered, energy consumption is reduced by 20-30%, depending on the material drying temperature. In addition to the standard blower with frequen-

cy regulation (from the construction volume of 300 m³/h) the new dryer is also equipped with Koch Öko’s patented energy management, which adapts to the drying process to save energy and protect the material, for maximum energy savings. By combining dew point control, Öko equipment and blowers with frequency regulation, up to 50% energy savings can be achieved when drying the granulate, says the company.
