digital synchronisation with the moulding process. The Syncro control unit supplies cold water to the mould only in the cooling phase, drastically reducing its duration. The Microgel Syncro product line features more than 10 models, with cooling capacities from 16 kW to 56 kW and heating capacities from 12 kW to 24 kW. The Microgel RS range of temperature control
units, which are available as single zone (RSM units) and dual zone (RSD) machine-side units, are designed for moulding throughputs ranging from 10 to 240 kg/hr. The new range includes advances in temperature accuracy over the entire control range (-5 to 90° C), pumping performance and energy efficiency. Frigel has expanded its adiabatic cooling product family line with the Ecodry MDK range, designed to allow the flexible configuration of modular adiabatic solu- tions for small to large plastic factories. MDK takes advantage of some of the technologi- cal advances already introduced in the LDK range. The new Ecodry MDK is designed to integrate easily into existing Ecodry 3DK systems, of which Frigel has an existing installation base of thousands of units. �

Auxilliary equipment group Moretto says that one of its Plast highlights, the OTX hopper, is the result of sophisticated math- ematical simulations used in its design which ensures a regular material flow, guaranteeing correct drying of each granule being processed. The optimisation of the process parameters has enabled the hopper
size, airflow and treatment time to be reduced by 40% for the same hourly output. The use of a smaller hopper allows the applica-

tion of a smaller dryer. Moretto has developed the Hyper Flow Turbo project capable of generating up to 2,400 m³/h of compressed air with the aim of creating a machine capable of using as little energy as possible. Compared with the regular Hyper Flow technology, Hyper Flow Turbo for the same performance consumes 4.8 kW/h, providing energy savings of 11.7 kW/h and cost savings of €35,800 per year, the company claims. X Comb is the latest addition to the company’s
range of dehumidifiers which has compact dimensions, making it suitable for treating small quantities of highly hygroscopic technical poly- mers. Moretto calls it a highly energy-efficient product intended for production-intensive sectors such as medical, optics and electronics.

Moisture Meter has the ability to detect the
percentage of residual moisture in the polymer without the need for off-line sampling. It is able to provide in real time the moisture value of the plastic granule after drying, allowing the operator to fix the situation if the resin has not been properly treated. Different versions are available depending on the type of installation and the hourly output of the polymer to be treated. Moretto has a wide range of blenders, including the DGM Gravix 20, the new gravimetric batch blender developed specifically for high-precision dosing of small percentages of material. The 20 series is built on the model of the Gravix series, but features a renewed design that improves granule flow. The storage line also includes Silcontrol, a system designed to control the loading of plastic granules into storage silos. The material, identified via a special barcode reader, is matched to the correct silo by interrogating the database. �

Piovan says that visitors to its stand at Plast will be able to see its the complete range of dedusting, feeding, conveying, storage, dehumidification, dosing, temperature control and cooling systems. A central feature is a system equipped with Modula centralised drying system, Easylink+ automatic coupling station, Quantum gravimetric batch blend with remote mixer, Easy3+ system centralised transport management, all of which is monitored by Winfactory 4.0, the Piovan supervision software to maximise efficiency of production processes. On show for the first time in Italy will be Con-
denso, Piovan’s fume condenser that minimises energy consumption and emissions thanks to a heat exchanger that transfers energy from the incoming hot air to the outgoing air, reducing the thermal gap with the dehumidifier with lower costs for both cooling and heating. In Piovan’s Aquatech brand, visitors can see the Aryacool+ adiabatic dry cooler, DigitempEvo water-cooled thermochiller and two models of the Easytherm water-cooled thermoregulators, one with an open system and the other pressurised. �

Wittmann Battenfeld is showing a SmartPower 400/750H/210S/525L Combimould machine at Plast, producing a re-usable three-component coffee-to-go cup with lid, which highlights its foam moulding technology. The Bornewables biomass- balanced materials from Borealis are used for both parts and the mould is supplied by Haidlmair. A
