Infrared Halogen Emitter 13908R

The infrared halogen emitter 13908R is a short-wave IR-A radiation source designed for industrial heating applications requiring rapid response, high energy density, and precise heat transfer. The emitter uses a quartz tube with a tungsten filament operating at high temperature, resulting in efficient infrared radiation concentrated in the IR-A spectral range.

Thanks to its short-wave infrared output, the emitter provides fast heat penetration into materials, minimal heat loss to ambient air, and immediate full power output after switch-on.

Industrial Applications

This infrared emitter is intended exclusively for industrial and technical equipment, not for general lighting.

Typical applications include:

• Drying processes (inks, coatings, paints)
• Curing processes (adhesives, lacquers, resins)
• Plastic processing
• thermoforming
• plastic welding
• shaping and softening
• Printing technologies (offset, inkjet, screen printing)
• Paper processing
• Industrial food processing (technical heating, tempering lines)
• Laboratory and testing equipment
• Localized zone heating in automated production lines

The emitter is suitable wherever high thermal output must be delivered quickly and precisely to a defined area without heating the surrounding air.

Operating Notes

• Instant full power output
• Continuously controllable output (0–100 %)
• High resistance to thermal shock due to quartz construction
• No emissions, no oxygen consumption
• Must be operated only in equipment designed for infrared heating with appropriate thermal protection
