Extrusion International 3-2017

24 Extrusion International 3/2017 MACHINERY AND EQUIPMENT A successful trade fair exhibition “The Plastpol 2017 has far exceeded our expectations with regard to networking and forging new contacts”, was the positive feedback given by Jacek Dobrzyński, managing director of the Plast Line Group, Wroclaw, a long-time distribution partner of motan-colortronic, Friedrichsdorf. The Plastpol 2017 was the 15th time that the Plast Line Group exhibited at the International Fair of Plastics and Rubber Processing in Kielce, Poland. “The Plastpol, being the most important trade fair for the plastics industry in Central and Eastern Europe, has always been highly significant for us, but Poland has also continued to be one of our most important markets”, added Jochen Freier, Sales Director Export at motan-colortronic. The focus of the companies’ joint exhibition stand this year were the portable dry air driers LUXOR E A and LUXOR EM A and the coupling system METROCONNECT U/C Mobile dry-air dryer for small throughputs In order to dry hygroscopic plastics for small material through- puts or stand-alone applications, motan has developed the new, mobile dry-air dryers LUXOR E A and LUXOR EM A. Equipped with a permanently installed drying bin, the com- pact dryer provides themanufacturer with 60, 100, or 150 litres of drying bin volume. The LUXOR E A models of the new range can be integrated into existing systems. They are designed to be connected to ex- isting conveying systems. Alternatively, they can be equipped with their own stand-alone material loader. The LUXOR EM A dryers, on the other hand, are self-sufficient, moveable stand- alone units, for isolated application, for example. As standard, they are equipped with integrated dry-air drying and a side- channel blower, as well as a small, monitored cyclone blower protection filter. The cyclone filter consists of an easy to clean fine filter cartridge and a transparent dust collection bin. The pipe work for dry-air conveying with rigid hose connections ensures that the suction box is protected from environmental air and filled with dry-air. This is why material can remain in the suction box even during down-times, as it continues to be a dry environment, protecting the material from reabsorbing moisture. The new dryers operate in a closed process cycle in combina- tion with temperature-controlled regeneration. Both dryer ranges are controlled and operated via the LUXORnet EM con- trols via a colour touch-panel with self-explanatory illustrated guides. All functions for drying, conveying and the operation of the proportioning valves can be set easily. A weekly timer is also integrated. Operation is also user friendly after a re-start: Employees need only to select the material which needs to be dried and start the system. Filling of the drying bin and thema- terial specific pre-drying then occurs automatically. The unit will signal when production can be started. Along with the in- tegrated databasewith the drying parameters of over 70 types of plastic, a second database is available for the customer with free slots for the parameters of up to 50 materials. Via an Ethernet interface the dryers can be integrated into ex- isting networks. This means that all functions can also be op- erated from a superordinate system. The drying system’s data can also be collected centrally. Both ranges can be equipped with options already familiar from larger drying systems, for example with a dew-point gauge, dew-point-controlled regeneration, or with ETA plus ® - energy saving technology with automatic air flow adjustment and temperature reduction. motan-colortronic delivers the dryers pre-installed with all chosen options. All functions are previously tested in a factory setting. Only the material loaders need to be set-up after delivery. After a short installation, the dry-air dryers are ready for use. A ben- efit regarding their flexible operation is the compact design of the dryers.
