MEDIUM WAVE INFRARED HEATING

  Efficient and economical infrared heating technology 

Medium wave infrared heating elements, are used in a wide range of industrial processes and offer a truly efficient and economical mode of heating. Infralight’s twin tube design with the gold reflector as standard, using high purity quartz, gives the user the best in  infrared heating technology: Fast, targeted heating, where the wavelength of the emitter is matched to the material being heated. Medium wave infrared heating  is robust in design and will withstand a large  amount of chemical, thermal and mechanical shock. Quartz tube is the most common type of material used for infrared lamps and infrared emitters. An alloy spiral element is housed inside a linear quartz tube, which is open to the air. Most medium wave emitters operate  between 800 and 1200C filament temperature. The peak wavelength is approximately 2 microns, and as quartz transmits infrared radiation up to 4 microns, the quartz envelope is around 300C cooler than the filament! This means that convective losses from the quartz outer surface are minimal, while the secondary radiation from this source at a temperature of 650C contributes to the total output of the infrared heater.

TWIN TUBE DESIGN WITH GOLD REFLECTOR

Approximately 70% of the input power is converted into radiant heat, the emissivity of the unit being that of the wire spiral, approximately 0.8 when in use. Twin tube medium wave elements are constructed in a figure 8 quartz section, which results in high strength design, extra rigidity over long lengths up to 4meters. The twin tube design offers a number of advantages including rigidity, robust, but also the ability to manufacture many different configurations. Terminating leads at one end is a clear advantage over other types of heating elements, as all leads are terminated at one end, making installation simple and inexpensive. No requirement to run extra cables.
