Heat without loss
from transport
Infrared and hot air are two classical methods for drying which are used quite often in combination. Both systems are also available separately.
Infrared dryers
Infrared dryers from Grafix prove themselves by economical continuous operation and a long operating life. Among other reasons, the double-quartz radiators with a power of 60 W/cm are responsible for that benefit. Thanks to their gold reflectors on the back, they achieve a radiation yield of 95 %. The drying process can be further optimised by the continuously adjustable control system. Furthermore flanking air nozzles assist the oxidative drying of the ink, cool the IR radiators down and protect them against accumulation of dirt.
Hot-air dryers/combined IR hot-air dryers
For drying glossy or protective varnishes, hot-air dryers from Grafix are the first choice. They take their large power efficiency from the high effectiveness of the compact hot-air cartridges (1.5 kW or 4 kW power) as well as from the heat that is generated in the module without any transport losses. Printing presses achieve special flexibility with Grafix combined dryers. They allow simultaneous printing and/or drying of conventional inks and varnishes or even fast changeover between different printing methods without the need of changing the dryers. During this process, the IR radiators which are up to 700 °C hot are additionally cooled down by hot air which has a temperature of "only" 200 °C.
