FAST DRY - Infrared and hot air drying

When talking about offset machines, today’s high capacity requirements oblige to achieve the drying of inks and traditional lacquers directly on the machines.
The ink drying process implies two main equally important aspects.
The first main issue is the evaporation of the dilution products, the second one is the chemical reaction, which takes place as an oxidation of the pigments. 
The choice of the dryer is determined by the composition of the inks and of the lacquers to be used.
Products not containing any water can be simply dried by an infrared dryer, while water-borne inks need some hot air in addition to the IR irradiation.
The short wave infrared dryer fast dry is equipped with an automatic switching on device for  the lamps, which are  activated by the sheets passing through. The system can also be partially switched on in case smaller formats are processed.
In this case the side lamps are switched off according to the paper sheet format, thus achieving a relevant energy saving.
The hot air dryer Fastdry is equipped with a heating coil, which feeds the air blades.
Both the air temperature and the air speed are adjustable to avoid turbulences and over-heating especially in case of very light sheets.

Both dryers are controlled by a user friendly touch panel.
