Product enhancements: LUXOR 80/120/160 and SPECTROCOLOR G
LUXOR 80/120/160 now available as advanced dryer
The tried-and-tested series of system dry-air generators – from 250 to 2400 m³/h – have been expanded by three more sizes: the LUXOR 80, 120 and 160. With these additions, the range now includes ten models, all ideally suited for centralized drying of all types of plastics granulates, particularly of high-end materials and engineering plastics in frequently changing batch sizes. Functions, such as conveying to up to 16 drying bins and 24 machine material loaders, have been added. In addition, up to three conveyor blowers can be employed. Any one of these advanced versions can easily be incorporated into all available motan drying bin systems. Furthermore, the drying bins in the 100 to 2400 litre series have been expanded by the LBA system bins with a capacity of 15, 30 and 60 litres. They are equipped with all essential options – as are the large models.
The LUXOR 80/120/160 models have been upgraded to the advanced version by adding an authentic dual-circuit process with two blowers and a closed-loop heat regeneration system. Moreover, the addition of pneumatic valves improves the process stability. The LUXOR 80, 120 and 160 generate either 80, 120 or 160 m³/h dry air with a consistently low dew point of up o -40° C. The installed molecular sieve cartridges operate alternately. This results in the safe and continuous provision of uniformly dried materials to the processing machines. The three new models are designed for material throughput of up to a maximum of 70/100/140kg/h.
Users have confirmed that this technology provides stable process management, minimal use of energy and a drying process that is entirely unaffected by the ambient air. This ensures that motan can guarantee maximum drying results – even under tropical climate conditions. These features meet the growing demand for leading-edge process technology in the small dryer sector. Simultaneous processing of a variety of high-grade raw materials or fast material changes are thus supported sustainably. There are no down times and no waiting for raw materials to be processed!
In this well-engineered small system, the efficient ‘energy saving package‘ ETA plus® is now being fully utilised for material drying. Here, the drying organizer function is combined with air flow control. The process air quantity and the adjustment of the drying temperature are controlled analogously to the energy requirement of the material throughput. ETA plus® avoids over or insufficient drying and guarantees maximum achievable drying quality of the granulate at minimum levels of residual moisture. Compared with conventional dryers, a reduction in energy consumption in excess of 60 percent are now achievable.
Interactive menu navigation is available via the clearly arranged TFT touch-screen colour monitor, thus considerably easing operation. Users are able to select all essential parameters for their chosen material from a pre-loaded databank. In addition, in-house formulae can be stored in a separate databank. Once the user has clicked the granulate of his choice, ETA plus® will take over automatic process control. All parameters required for the entire drying process are stored in the database. The equipment adapts – with regard to quantity, conditions, summer, winter, day or night – and proceeds with the drying process meeting all requirements in an energy-efficient manner.
SPECTROCOLOR G – Increased profitability in extrusion due to sustainable materials handling
To satisfy the most stringent quality requirements in production and –simultaneously – striving to keep overheads consistently low is the two-fold challenge not only confronting the plastics processing industry, but also plastics machinery manufacturers. Blending and dosing different materials to be processed is given utmost priority: Accuracy of the formulations and consistency are key to product quality, and ultimately to profitability. Adding to motan’s know-how in the blending and dosing systems with its Graviblend and Graviplus units, the SPECTROCOLOR G now enters the extrusion market building on the Spectrocolor V volumetric version. motan, the global leader in materials handling for the plastics industry, expands its comprehensive product portfolio designed to cover all areas of volumetric and gravimetric materials blending and dosing. The compact SPECTROCOLOR G of modular design for LIW (Loss-In-Weight) dosing of free-flowing granular material and regrinds affords the user a unit with an excellent price-performance ratio. Traditional application areas are flood-fed single screw and starve-fed twin screw extrusion. This means that the entire production bandwidth, including pipes, profiles, flat film, cast film, and plastic sheet materials is thus covered. An extensive range of tests – under continuous operational conditions – confirm a consistently high dosing performance combined with a dosing constancy of up to 0.5 percent. As a consequence, maximum process dependability and reliably accurate repeatability are assured.
The SPECTROCOLOR G is suited for the addition of six components with a respective throughput range of between 0.2 to 1200 kg/h per dosage axis. All metal parts in contact with the granulate are made of stainless steel; all weighing hoppers are equipped with glass sight slots to accommodate filling level inspection. Automatic calibration and recipe data storage for a number of mixing formulae come as standard. In order to monitor product quality, the weighed and blended quantities are constantly compared with the nominal values via feedback control. Data exchange, data control and the networking of the LIW process data records are achieved via a standard Ethernet interface for complete material management. A small PC with a 5.7” touch-screen colour monitor communicates with Soft-SPS. By means of an optional OPC server, the SPECTROCOLOR G technology is able to exchange data with super-ordinate BDE process management systems and data banks.
