Infrared heating tube classification
According to infrared radiation wavelength: short wave, fast medium wave, medium wave, long wave (far infrared) infrared heating tube
According to the shape: single hole, double hole, special-shaped heating tube (U-shaped, Omega-shaped, ring, etc.) heating tube
Divided by function: transparent, ruby, half-plated white, half-plated, fully-plated (coated), frosted heating tube
According to heating material: halogen heating tube (tungsten wire), carbon heating tube (carbon fiber, carbon felt), electric heating tube
