The carbon fiber infrared electric heating tubes used in light wave saunas and steam rooms are long-wave infrared electric heating tubes with low power, and their power is less than 500w. The double-layer carbon fiber infrared electric heating tube used in light wave sauna and steam room has the characteristics of corrosion resistance, explosion-proof, high strength and long service life.

The infrared wavelength of carbon fiber infrared heating tube is between 6-15 microns, of which more than 60% are concentrated between 8-15 microns. This wavelength matches the absorption wavelength of the human body, which is very easy for the human body to produce harmonious vibrations. 60-70% of the blood in the human body is composed of water molecules. When the far-infrared rays act on the human body and produce a "resonance absorption" effect, they recombine into smaller water molecule clusters. In this process, the pollution adsorbed on the surface of the water molecules is caused. Substances can be removed, increasing the water molecules attached to the cell surface, increasing cell activity and surface tension, improving cell metabolism and blood circulation, especially human microcirculation.

The carbon fiber infrared heating tube adopts a double-layer quartz glass tube, the inner layer is a quartz glass tube with a diameter of 10-12mm and a wall thickness of ≥1.1mm, and the outer layer is a quartz glass tube with a diameter of 18-20mm and a wall thickness of ≥1.5mm. The outer quartz glass tube has a large diameter, thick tube wall, high strength, high hardness, good corrosion resistance, explosion-proof, etc., and good safety during use.

The carbon fiber electric heating tube has no light pollution, no irritation to the eyes and skin burns, no ultraviolet radiation, harmful gases and high-frequency radiation. The carbon fiber electric heating tube has strong acid resistance, corrosion resistance, very small thermal expansion coefficient, and high thermal stability. It can withstand severe temperature changes without bursting, so it has strong resistance to sudden changes in cold and heat.
