Quartz Infrared Heat Lamp is used in many industrial heating applications, including PET blow molding, silicone extrusion curing, and coil coating.

Quartz Infrared Heat Lamp contain a tungsten filament encased in a quartz envelope. Tungsten is a resistive element that is capable of surviving temperatures in excess of 2750 oC. Tungsten responds rapidly when a voltage is applied. In less than 1 second, over 90% of the available IR energy is available. This rapid response will yield several control benefits, including short oven warm up times and high levels of repeatability. The quartz envelope allows transmission of the IR energy, while protecting the filament from convective cooling and corrosion. The quartz is evacuated and filled with inert gases. A small amount of halogen gas is added to promote long life of the emitter. Rated life for most T3 lamps is 5000 hours. Actual life will depend upon the application and environment and may be greater or less than rated.

The lamps are available as a linear source from 2 to 50 inches (51 to 1270 mm) in length, with wattages up to 300 watts/inch.
