IR curing ovens do the curing process of the paint on the material directly without the need to heat the oven interior. The advantages of this system over others can be listed as follows.

In IR curing furnaces, there is no need to preheat to increase the temperature in the furnace as in other systems. Both time and energy are saved.
Air circulation can be added according to the dimensional properties of the material to be cured. Since there is no need for any air circulation in two dimensional materials, dusting on the material is minimized and the painting quality is increased.
No extra setup space is required like other Convectional ovens. It can even be used by placing it on the front or back of the convectional system.
