Inerted Systems

Inerted systems are used where the chemistry requires a reduced or near oxygen-free environment. This is usually accomplished by flooding the curing zone with nitrogen.

Quartz plates may be used between the curing lamp and the substrate to prevent chemical out-gassing from dirtying the inside of the irradiator and reflector, and are used in inerted systems to separate the air-cooled area around the lamps from the inerted area containing the substrate.

As an enhancement to dichroic reflectors, quartz plates may be coated to be reflective of IR and long wavelengths. These are referred to as “hot mirrors.”
