EXHIBITION REVIEW | PLAST 2018
Right: Plas Mec showed two flagship machines, the Combimix-HC and TRR container mixer, to celebrate its 50th
birthday
designed and calibrated specifically for this, but have merely been adapted. “If they are effective in the process, their costs
and energy consumption are high because they were not conceived for this kind of application, and energy outlays push up production costs,” said the company. “If they are inefficient, their initial costs are lower, but they have to be run at full capacity: expensive maintenance and imprecise temperature control negatively impact finished product quality and costs.” When processing plastics, the temperature
ranges to be maintained for different processes can vary by 50°C or more, demanding different pressures and flow rates from the chiller. Piovan says that Easycool+ is flexible enough to maintain optimal working conditions at all times. The range employs ‘plug and play’ technology with integral circuitry in the machine: eight differ- ent hydronic versions available for each model, with or without thermal storage, and specific versions for use at extremely high flow and pres- sure. A system built with Easycool+ is sized to ensure the lowest possible refrigerant load, says Piovan. Power ranges from 60 to 250 kW. Two different types of evaporators are available:
brazed plate, which is normally used when clean water is to be used in the cooling process; and shell and tube, for situations where treated water is not available.

Moisture metering Moretto put considerable emphasis on its new Moisture Metering Manager (MMM). “Before now, there has not been a drying system
that measured original humidity in the granules,” said business development director Paolo Gasp- arotto. “The MMM can determine exactly the right amount of dehumidification necessary to obtain the desired ppm levels in the material. This is a form of energy on demand.”
The MMM enables product certification, which is
important for the automotive industry, he said. The MMM reads moisture content of the resin
itself, rather than the surrounding air, by measuring changes in electromagnetic waves. Two Moisture Meter sensing units, one above the hopper (Moisture Meter Crown) and one below the drying hopper (Moisture Meter Box), read ‘before’ and ‘after’ levels. The drying process varies according to these readings. As standard, the MMM stores data profiles of 15 most commonly used materials, and new material profiles can be added. The MMM is part of Morettto’s Eureka Plus drying system concept, which brings together the MMM with its X Max resin drying system with ultra-low dew point, the Flowmatik airflow manage- ment system, and OTX drying hoppers. Moretto says that processors using Eureka Plus have on average cut energy consumption by 56%, compared to conventional drying systems. Still on the theme of energy efficiency, the company also presented its new modular cooling concept for heavy-duty applications, X Cooler. This is equipped with screw compressors with variable- flow, high-efficiency evaporators, centrifugal ducted fans and electronic expansion valves.
