IR MEDIUM WAVE QUARTZ EMITTERS

IR medium wave emitters heat surfaces and thin materials quickly. Plastics, water and many solvents absorb radiation at this wavelength particularly well, which makes medium wave a strong fit for drying and surface heating.

At a glance

  • Radiation peak: 2.2-3.2 µm
  • Maximum nominal power density: 35 W/cm
  • Maximum surface power density: 60 kW/m²
  • Filament on/off response: 30 to 70 seconds
  • Working position: horizontal (vertical on request)

How it works

Helios designs the emitter so its peak radiation wavelength matches the absorption curve of the material being heated. That match is what delivers an efficient process with lower energy consumption. A gold, white or ruby reflector can be applied straight onto the quartz tube to direct the emitted energy onto the target.

Tubes, filaments and reflectors

Twin tube emitters can be built with different filament configurations, which gives flexibility in both the heated area and the cable position.

Applications

Medium wave emitters suit drying and surface heating where the material absorbs well in the 2.2 to 3.2 µm band: plastic films and parts, water-based coatings and solvent evaporation among them. They are used across plastics, printing and general industrial drying lines.

FAQ

Which wavelength should I choose?

It depends on what your material absorbs. Medium wave (2.2-3.2 µm) works well for plastics, water and solvents. For faster on/off cycling, look at fast medium or short wave. The Technical Center can test your specific material.

Single tube or twin tube?

Twin tube gives the best mechanical strength thanks to its reverse “H” profile and can be built up to 6.5 metres long. Single tube versions are also available.

Can I add a reflector?

Yes. Gold, white or ruby reflectors are applied directly to the quartz tube to focus more energy on the material.

Can the emitter be made to a custom length?

Yes. Total length, heated length, filament and ending configuration, power and voltage are all set to the application.
