Far infrared heating element as well translucent quartz tube as infrared radiation, without surface coating, without infectant, without bad radiation, excellent chemic & heat stability, high temperature resistant, various shaped, ametabolic long using, Heating temperature selective, unchangeable radiation ability in long-term. Long using life, Structure reasonable, infinitesimal heat inertia, make used of convenient.
Quartz electric heating tube is an electric heater in which a heating wire is placed in a quartz tube. Because the quartz tube has the function of selective far-infrared radiation, it does not need far-infrared coating compared with other heating elements, and the spectral radiation matching absorption characteristics are good, the long-term use radiation performance is not degraded, and the electrothermal conversion efficiency is high, compared with the general heating element. Energy saving is about 30%; fast heating, low thermal inertia, high temperature resistance, corrosion resistance, good thermochemical performance, long service life, high insulation strength, no pollution; short thermal response time, especially suitable for heating occasions that are often shut down It is very convenient, economical and safe to design, manufacture and install.

The far-infrared heating tube is an opal quartz glass tube processed by a special process. It is equipped with a resistance composite material as a heating element. Because the opal quartz glass can absorb almost all the visible light and near-infrared light radiated by the heating wire, and can make it Because the current industrial infrared heating tube basically eliminates the milky white quartz tube, because its material is relatively brittle, it cannot form a very long milky white heating tube. And the milky white has a shading effect, blocking its wavelength. Because of its high tube wall temperature, it is only suitable for near infrared heating.
