C-SYS Drying

Drying without heating of workpieces, vacuum drying

Most of all, vacuum drying is an industrially used widespread option to dry workpieces and products quickly and without additional heating .

As always, we focus on innovation for our vacuum driers instead of sticking with the status quo! In principle, the procedure is simple: The ambient pressure is reduced, the boiling point of water decreases, and as a result, the residual heat of the workpiece is used to evaporate the water on the workpieces.

 Quick!  Small space requirement!  Efficient use of energy!  Tight / low maintenance!

This means this process is always tied to the energy, i.e. the heat of the workpiece. Likewise, the quantity of the water introduced determines the effectiveness of the drying process. When the vacuum chamber is completely evacuated, there is little movement around the workpiece. This then requires intermediate ventilation and renewed evacuation.

In order to optimise these two factors, C-SYS has developed its own patented vacuum dryer.

The vacuum chambers of our vacuum dryers always consist of solid materials, which form the cast of the workpieces. In case of complex loading and unloading concepts, these chambers are made of solid aluminium plates, and the interior space is lined with these as required.

As the air volume is minimal, air evacuation within the shortest time is possible. This means we can always achieve an excess of power of the vacuum pumps. This excess enables a repeated “intermediate ventilation” of the vacuum chamber or drying with permanent artificial leakage.

This drying procedure and the design of the vacuum dryers minimises the cooling and icing over of the workpiece, and the condensate formation that can be sucked up is promoted through the possibility of fresh air supply.

“Hot” workpieces for example at 50°C are not required for the full function of the C-SYS vacuum dryer. Even after cold wash processes at 30-35°C, our vactrains provide perfect drying results.

If the temperature of the workpieces should decrease too quickly after all (for example due to waiting times, long cycle times or similar), we can equip each vacuum dryer with workpiece heating, which is highly efficient, bringing the workpieces to a suitable drying temperature within seconds.

Naturally, the C-SYS vactrain can also be combined with our pre-drying modules (SurfaceAircleaner), to be able to completely dry even absorbent workpieces that have drawn a lot of water.
