LUXORCentral drying systems
Today‘s plastics processor expectsnot only a drying system thatfunctions in accordance withtechnical specifications, but one thatalso meets the basic requirementsfor reliability, economy of operations,and finished product quality.
Innovations included in the LUXORseries of dryers, such as theETA-process®, the DryingOrganizerand state-of-the-art PLC controltechnology has given Motan aposition of unrivaled leadership inproviding products and solutions thatassure a consistent improvement inquality, and economy of operations.
Customer-centered drying solutions for plastic processors
Motan design and development engineers continuously focus their energies on providing innovationswhich are responsive to the needs of our customers.
Quality
Ultimately, processors require systems that provide them with consistent finished-product quality.Motan‘s twin bed drying systems are designed with closed-loop cooling during the regenerationphase to give consistently low dew points throughout the drying process. The DryingOrganizer andat-the-bin heating of all materials assure precise temperature control. In addition the DryingOrganizerguarantees that materials do not become over or under-dried. Dry air conveying, line purging and self-diagnostic controls further assure that our customers have properly dried material, without thedefects caused by improper drying.
Reliability
Plastic processors in every corner of the world rely on Motan‘s robust, efficient design to providethem with unrivaled reliability. At-the-bin heating with ETA-process® energy-recovery furtherenhances the efficiency of the operating process. The use of commercial PLC controls, and readilyavailable system components, assure that Motan products are the industry‘s most reliable.
Economy
Motan‘s systems operate at maximum efficiency and with a minimum of operating maintenance.The integration of central drying, dry air conveying, line purging and manifold systems (both manualand automatic) provides our customers with maximum flexibility, production up-time and minimalloss of valuable production time during material changes. Motan’s patented ETA-process®
technology provides the industry’s most energy-efficient drying system.
LUXOR
Conveying
A hopper loader madeof stainless steel andglass is mounteddirectly on the dryingbin. Motan’s hopperloaders are equippedwith an implosionvalve for efficient filtercleaning after everyconveying cycle.
LUXOR central drying systems
The dryers of the LUXOR seriesare equipped with two stationarymolecular sieves, efficientlyinsulated at critical points. Closed-loop aftercooling of the molecularsieve with dry air ensures acontinuously low dew point and amaximum drying performance.
LUXOR controls
Simple handling by modern, PLC supportedcontrols with Siemens technology. There aredifferent types available to operate the dryer asan individual station or part of an integratedcentral system together with conveyingsystems and mixing units.
The LUXORnet control offers simple, userfriendly operation via a colour graphic displaywith intuitive touch-screen controls. Itincorporates comprehensive facilities foroperation and process control. Enhanced
service functions include histograms, an optionalintegrated conveying control and theDryingOrganizer, for controlling drying temperaturein relation to material throughput. A modern, opennetwork architecture based on Internet technologyenables easy linking to complementary componentsof the Motan CONTROLnet suite, for integration ofcontrols for all stages of material handling andprocessing.
Suction box
Precise metering of dried material into thevacuum stream is assured with Motan‘s suctionbox. It enables material to be conveyed to theprocessing machine after drying without anyincrease in moisture levels. Dry air conveying andline purging is available as an option.
ETA-process®
Motan‘s patented energy-recovery system savesa lot of energy by using the drying bin exhaust airto preheat incoming process air. This technology,coupled with DryingOrganizer, not only assuresthat the material is properly dried but also allowsfor precise temperature adjustments that virtuallyeliminate the danger of defect due to over-drying.
LUXOR drying bin
All Motan drying bins are made of stainless steelas standard, are fully insulated and are equippedwith large clean out doors and a sight glass.
Material selection station
Motan‘s coupling station provides the operator withquick and easy methods of directing material fromsource to destination. Proofing and fully-automatedstations are also available to give maximum securityand effectiveness.

Motan‘s ETA-process®
Energy efficiency has always been a primary concernin the design of Motan central drying stations. Aclosed-loop cooling not only saves energy, it will alsoavoid the regaining of moisture by the molecular sieveduring the regeneration phase. With the ETA-process®
you regain energy from the return air directly at the binvia an integrated heat exchanger (optional). A thermalbarrier in the drying bin prevents energy loss via thehopper loader.
LUXOR drying with ETA-process®
technology
Drying
A clearly determined residual moisture of thematerial guarantees minimal production ofscrap. The first step towards high qualityproducts thus means drying of plastic granuleseven before processing.
For the correct drying of plastics an extremelylow dew point of the dry air flow is required.The dry air also has to be hot enough to causethe moisture to be released by the material.
The air is first dehumidified by being passedthrough a molecular sieve and afterwardsheated up to a material specific dryingtemperature. This hot dehumidified air is nowpassed through the material to remove thewater molecules, and then back to themolecular sieve again in a continuous process.After the recommended drying time haselapsed the material can be processed withoutproblems.
DryingOrganizer
Drying for too long at high temperatures maylead to thermal degradation with some plastics.The DryingOrganizer prevents this in loweringthe temperature related to the material
throughput. In case of production interruption, thesystem lowers the actual temperature to the standbylevel. This saves energy and keeps the material dry.Sensing the material throughput and monitoring toohigh levels, is an additional advantage.
