Dry air dryer
LUXOR A

LUXOR A series dryers with ETA-process® and ETA plus® energy saving technology are specifically designed for supplying dried plastic granulate for many different plastics processing applications. They have either two or three fully insulated stationary desiccant beds with separate process and regeneration blowers which provide consistently low dew-point air to the process, while reducing energy consumption.
The advanced LUXOR A series consists of ten models with drying capacities from 80 to 2400 m3/h. Each advanced system dryer can be flexibly combined with all LUXORBIN A drying bins from 15 to 2400 litres. In addition, motan offers a range of extra-large drying bins with volumes from 3,000 to 13,000 litres. These are also available with gas heating. All motan system drying bins are made of stainless steel, are completely insulated, and have individual heating as well as temperature control.
All LUXOR A drying systems have a LUXORnet control and utilise modern, flexible Bus-technology. As standard, LUXORnet manages the dry air generator, 16 drying bins, and up to 24 machine hopper loaders. The integration of dry-air conveying, line purging, as well as manual and automatic manifold stations provide maximum flexibility and productivity.

Dry air conveying
Easily expandable No product redundancy - as your production requirements change so does the drying station.

Because of a fully modular concept and a wide range of products, motan can react flexibly to all your process specific demands. Different sized dry air generators and material bins with integrated heaters allow for easy expansion. As your production requirements change, so does the drying station.

Integrated conveying Saves money - no need to buy a separate control.

The integrated conveying function in the LUXORnet control saves you money as no separate conveying system control is needed. It can control up to 16 material loaders on the drying bins and 24 loaders feeding the processing machines, as well as blower stations and a stand by blower.
For the installation of large complex systems, you can network multiple LUXOR drying stations with each other or with other motan controls of the CONTROLnet family. This guarantees a high degree of flexibility. A central WEBpanel provides an overview of the entire production.

Desiccant beds Large and stationary -saving energy, ensuring reliability and guaranteeing dry air quality.

Each dryer is equipped with either two or three fully insulated stationary desiccant beds. The benefits to you are: large quantities of molecular sieve, which means long drying cycles, infrequent regeneration, and no moving parts. This saves you energy, gives you reliability, and guarantees consistent and stable dry air quality.

Closed loop regeneration Less frequent bed switching - reduces energy costs.

Finding better ways to save energy has always been a focus for motan. For example, during regeneration when the desiccant beds are heated up, a heat exchanger is used to regain the energy from the hot, moist exhaust air and to preheat the incoming air. Closed loop cooling is then used in the cool down phase so that only dry air is used. This results in less frequent switching of desiccant beds, saves you energy and avoids moisture reabsorption prior to switch over in the drying process.

Molecular sieve Reliable with a long service life.

Each time molecular sieve is regenerated it needs to be heated up and then cooled down. This causes friction and generates dust which blocks the moisture trapping pores in the molecular sieve. motan uses specially designed and prepared molecular sieve with a high mechanical and chemical stability. This reduces the frequency that the sieve needs to be exchanged and ensures optimum dry air quality.

ETA plus® technology Innovative and energy efficient drying technology which saves you money.

ETA plus® technology stands for innovative and energy-efficient drying technology which takes three individual factors into consideration:

 

  • The air flow control adapts automatically to the amount of material being dried as well as to seasonal and time-of-day related fluctuations.
  • Once the air flow has been reduced to its minimum value, the drying temperature adapts automatically to the amount of material being dried. This guarantees very gentle drying, especially when there is a large drop in material throughput rates.
  • When drying with high temperatures, the heat recovery exchanger is a sensible choice because it uses the high exhaust air temperatures to preheat the process air, resulting in a significant reduction in energy consumption.

Altogether, the combination of air flow control and temperature reduction offers the highest possible energy savings. Compared with conventional drying systems, energy savings of up to 64% are possible with ETA plus® technology.

ATTN technology Essential for drying critical plastics where predefined moisture contents are required.

ATTN, motan’s automatic temperature and dew-point control system, maintains a constant dew-point of the process air. It is essential for materials that require a predefined moisture content and will be damaged if over dried as a result of too low dew-points.
The combination of ATTN and ETA plus® is possible and makes sense, since the control of air volume and the automatic adjustment of the temperature optimally supports proper drying at a constant dew-point: ATTN keeps the dew-point constant while ETA plus® controls the air volume and drying temperature.

The four drying parameters Optimum drying results in the correct combination of all four drying parameters.

An energy-efficient drying is only achieved by optimally combining the four drying parameters: dry air flow, drying time, drying temperature, and dew-point. Often, it is presumed that a lowest possible dew-point is synonymous with best drying results. As can be seen with ATTN, this is not always the case. Most hygroscopic materials only require a 20°C dew-point for correct drying – so why waste energy generating lower dew-points when they are not needed!

Heating at the bin Fully flexible and saves energy with individual drying temperatures.

Flexible drying systems require individual drying temperatures at various drying bins. We only offer "cold" dry air generators. Heating of the process air takes place right at the drying bin and is individually adjustable. The benefits to you are:

  • No energy losses in the dry air ducting from the dry air generator to the bins. 
  • You are completely flexible in expanding the drying station in line with your production needs: any bin size can be added and each can run at a different drying temperature.
LUXORBIN geometry Drying bin geometry. Essential for correctly dried material.

The ratio between the height and diameter of a drying bin is critical to how a material flows through the bin. Incorrect mass flow can lead to "dead" corners where the material is over dried or the material will flow too quickly through the middle of the bin resulting in under dried material. The optimum dimensions of motan LUXORBINs are determined by calculation and practical tests, guaranteeing correctly dried material is delivered to your processing machine.

Large clean out door Easy access and quick clean down.

The larger LUXORBINs from 100 to 2400 litres are equipped with especially large cleanout doors fitted with a sight glass and easy-to-open quick release handles. They fit the shape of the bin in order to optimise material flow and simplify cleaning. In addition, they have a split hinged lid for easy access from above.

LUXORBIN construction Designed for reliability and a long life.

All motan LUXORBINs are made of stainless steel and are completely insulated including the bin cone. The bins are mounted on solid frames and have a control box mounted at the front of the bin for optimum accessibility. The long-life solid state relays guarantee precise and reliable temperature control that does not damage thermally-sensitive materials.

LUXORnet State-of-the-art control with innovative, Ethernet-based open network architecture

The LUXORnet control offers user-friendly operation via a colour graphic display with touch screen. LUXORnet incorporates comprehensive functions for operation and process control, recipe management, reporting for quality assurance, as well as enhanced service functions and trend charts. ETA plus® airflow control with temperature adaptation is available as an option.
To simplify the input of the material-related drying parameters such as drying time and temperature, a material database is integrated in the control. The database includes a data pool with parameters for about 70 standard materials and can accommodate up to 100 data sets as specified by the customer.
All LUXOR A drying systems have a LUXORnet control and utilise modern, flexible Bus technology. As standard, the control manages the dry air generator, 16 drying bins, as well as up to 24 machine hopper loaders.
LUXORnet technology stands out due to its modern, Ethernet-based open network architecture enabling standard networking with all other motan CONTROLnet controls.

Line purging Ensuring correctly conditioned material is delivered to the machine.

Conveying from the drying bin to the processing machine is done via a no-dead-space suction box made of stainless steel with an integrated purge facility, guaranteeing very low residual moisture content and a constant material temperature. Dry-air conveying with automatic line purging is available as an option.

Dry air conveying Maintaining material temperature and eliminating reabsorption of moisture.

Dry air conveying is essential for hygroscopic materials which reabsorb moisture quickly. Conveying is carried out in a closed loop and dry, warm air is used for transporting the material to the processing machine, maintaining material temperature and eliminating reabsorption of moisture.
