Far infrared heating tube, also known as halogen heating tube, the basic structure is putting tungsten filament into quartz tube. The filament design and shell will makes the luminescence spectrum stable in 2400-3500 K. It has many advantages:

• Fast temperature raising and cooling.
• Good far-infrared radiation, advanced hygienical function.
• High thermal efficiency, high density.
• Long life span.
• Strong resistance cold and hot flash degeneration.
• Good acid and corrosion resistance.
• Stable electrical Performance.
