Hemlock Far Infrared Sauna used for far infrared emission source
(1) Tourmaline: commonly known as "Tomarine stone", tourmaline needs to reach a certain degree of temperature to emit a small amount of far infrared, its own can not be directly conductive, to receive heat indirectly from the conductive heat film, so as to emit far infrared, the wavelength can not be controlled, it is easy to exist harmful to human body rays, the highest energy consumption. Now natural tourmaline has very little, the tourmaline sold on the market, mostly synthetic, low cost, quality is self-evident.
(2) Far infrared ceramic tube: It has the characteristics of high efficiency, high strength, safety and ultra-long service life. The far infrared biological spectrum emitted by pure ceramic tube is very close to the human body's own wavelength, which is easier to be absorbed.
(3) Far infrared heating plate: far infrared emission wavelength is accurate, the emitted far infrared wavelength is 6-14 microns, consistent with the human physiological rhythm, low energy consumption, accurate surface temperature control. But the manufacturing process is complicated, the core technology is difficult to master, the material cost is high, the price is high.
The wood from which the sauna is made
(1) camphor wood, white pine, camphor pine: wood density is general, producing area is more, easy to obtain, the price is low, but easy to corrosion, easy to deformation, no texture.
(2) Hemlock: also known as hemlock, produced in Europe and the United States, high wood density, natural and fresh wood grain, good texture, corrosion resistance, no deformation. But the processing technology is complex, the cost is high, and the price of the sauna room made of it is higher.
(3) Fragrant cedar: also known as red cedar, produced in Europe and the United States, wood density is high, wood grain is elegant and noble, can issue a permanent natural wood fragrance, corrosion resistance, no deformation, sauna made of it has a collection value. But the processing technology is complex, the cost is high, and the price of the sauna room made of it is high.
