Infrared Powder Coating Ovens
Infrared heaters create molecular movement in the paint and surface coating without heating the entire mass or air for all products requiring heat.
In this friction-based heating, the entire product to which the paint is intended to adhere does not heat up; only the product heats according to the heat transfer coefficient from the metal surface to the depth of the mass.
Infrared heaters do not need to heat the air or rely on air for heat transfer as in conventional systems.
They directly heat the surface being coated and the paint or coating applied to the surface.
For this reason, curing and heating are completed in a shorter time.
Advantages
- Gas-fired infrared heaters generate heat through an exothermic reaction, so there is no open flame combustion on the surface, making them safe to use in flammable and explosive environments.
- Since there is no open flame, no harmful gas emissions occur, allowing heating without damaging the environment.
- Because curing times are shorter, these ovens can be installed in much smaller spaces compared to conventional ovens.
- Economic heating and curing occur due to direct heating in a shorter time.
