gas fired infrared ovens that precede the traditional convection ovens, rapidly raise the powder coating temperature to a point where the powder flows and gels delivering the parts to the convection oven close to cure temperature in a short amount of time. gas infrared oven have proven to be a cleaner combustion, free of regulated emission gasses, while emitting a very cost effective form of infrared that is more efficient in raising the coating temperature than traditional convection coating ovens.
