Twin-tube infrared quartz emitters deliver high power density radiant heating in a compact footprint. The H-iron twin tube design increases watts per linear inch, improves structural strength, and supports longer heating spans than single-tube emitters. Available in short wave, tungsten medium wave, carbon medium wave, and NiCr medium wave configurations for industrial drying, curing, thermoforming, coating, and process heating applications.
Twin-tube infrared quartz emitters deliver high-power industrial heating in a compact footprint. In addition, the H-iron twin-tube design increases strength, supports longer heating spans, and provides higher watts per linear inch than standard single-tube emitters.
As a result, the twin-tube profile improves heat focus and overall system stability across wide heating zones. Because of this, manufacturers commonly use twin-tube emitters in drying, curing, thermoforming, laminating, coating, printing, textile production, and industrial oven systems.
Furthermore, Emitted Energy manufactures twin-tube infrared quartz emitters across four emitter categories. Each category offers different wavelength ranges, response times, and heat output levels to match specific process needs.
