DARC® – DARK RADIATION CONVECTION

The DARC® technology is a method developed by us that uses a heating up process in powder enamelling furnaces and paint dryers based on a mix of convection (circulating air) and long wave infrared radiation, the so-called “dark radiation”.

Thanks to the functional principle, the application of a DARC® furnace provides many benefits compared to a conventional circulating air furnace.

Advantages of the DARC® technology at a glance:

economic drying and enamelling of paints on large, heavy and three dimensional workpieces
up to five times higher energy transmission onto the workpieces
reduction of workpiece heating-up times by up to 70 %
space-savings thanks to reduced holding space inside the oven
quicker heating-up and enamelling times than in conventional circulating air furnaces
combination of very thick and very thin material thicknesses is possible
simultaneous enamelling of different poweder coat colours without mixing

Areas of application of the DARC® technology:

chamber furnace
continuous furnace
booster
dryer for liquid coatings
dryer for cataphoretic paints
adhesive water dryer
tempering furnace
