A low density,
medium wave infrared emitter, the IQH quartz tube has been developed for
thermal processes that require medium wave infrared. The IQH has high
heating rates in up to 50 watts/in. The unique, patented filament design allows fast heat-up times of 6 seconds, as compared with 30
seconds for conventional quartz tubes. The IQH tube produces mostly
medium to long wavelength IR, with a filament
temperature from 700 to 1000 °C (973 to 1273 °K). The tubes can be banked
together to produce a uniform area heat. The IQH tube is for horizontal
burn applications only. The filament wire is an iron/chromium/aluminum
alloy that has a nearly constant resistance from room to operating
temperature. Less expensive distributed zero cross power controls can be
used, which simplifies system CE approval.
