efficiency systems dedicated to packaging and the beverage sector. For the large-scale dehumidifica- tion of PET granules, Moretto presented a drying system consisting of a XD 800X series dryer combined with the OTX hopper and Moisture Meter Manager. This solution is able to guarantee certifiable results, energy efficiency for any type of material and a completely automated drying process.
Motan Colortronic has developed the Luxor CA
A advanced compressed air dryer in 15, 30 and 60 litre sizes. The unit has the company’s ETA Plus throughput-based control for a temperature range of 30-180°C. The compressed air dryers have a fully insulated stainless steel drying bin, sight glass and hinged lid with mounting flange for a Motan hopper loader. Heating is with a temperature regulator, air flow meter and fully adjustable air flow mounted on the bin. It is suitable for installa- tion on the intake flange of the processing ma- chine. The 30 litre drying bin has an air volume of 6-15 m3
/h, while the 60 litre version is 10-25 m3 /h.
ProTec Polymer Processing has introduced the SOMOS RDF modular resin drying system for flexible stationary use without a central dry air generator. The system consists of autonomously operating units with their own Industry 4.0-capable controllers. Depending on requirements and desired throughput, the individual modules can be combined into a variable overall system with central visualisation and control. Depending on the required throughput, the company says that the modular stationary RDF (Resin Dryer Flexible) drying system can be made up of a number of independently operating drying modules. Components are available with capacities of between 50 and 400 litres, each one being individually controllable by its own controller. Alternatively, when interconnected, they can be controlled using a common operator control unit. As standard, they offer drying temperatures of 60-140°C and high-temperature variants for up to 180°C are also available. Each module has an integrated air generator, ruling out complete failure as may occur with a centrally supplied drying system. The modules are compact and, in comparison with a central drying system, do not require extensive supply and return air piping. The RDF modular drying system also saves energy because only the components which are actually required are operated. If requirements change, modules can be simply added or removed. The RDF modules also have an Industry 4.0-compliant PLC controller capable of storing up to 200 formulations. They

have their own dry air generators and also provide various smart energy-saving systems. The drying air volume is automatically adapted to actual through- put while regeneration cycles are controlled on the basis of the actual water content of the pellets. Vismec has developed a line of wheel dryers
that now require around 40% less energy. They can be pre-set and provide a constant dew point of between -20°C and -50°C. The process and regeneration air flow is adjustable and there is no water or compressed air connections. They offer material protection against under- and over-drying at drying temperatures of 50-180°C. The dryers have a new touchscreen control. Versions include the DW 14 Medical with H6 drying hopper, which is built completely in stain- less steel and includes filter housing and air pipes. The DW 25 Touch Screen with H30 drying hopper is on a compact frame with fully insulated suction box, while the DW 80 with H150 drying hopper and inspection door is also on a compact frame with fully insulated suction box. The company also offers a portable dew point controller with an internal vacuum pump that guarantees ideal air flow through the dew point probe.
