Infrared is widely used for industrial heating or drying, such as surface heating, drying, and curing processes in the fields of automobiles, plastics, printing, glass, textiles, food, metal parts, circuit board packaging, film, and electronics.

Quartz near-infrared and far-infrared radiation spectra can be generated by using transparent or semi transparent quartz glass as the outer shell of the lamp tube. Infrared is a type of electrical wave that propagates at the speed of light and carries high energy. The radiation intensity and wavelength of different types of infrared with the same power vary.

A. Long wave infrared (also known as far-infrared) has the characteristics of fast heating speed, uniform heating, small thermal inertia, and only 1-3 minutes to reach the constant temperature of the component. The electrical radiation conversion efficiency is as high as 60% -75%, and it does not explode in cold or hot conditions. It has a long energy-saving service life, generally up to 8000 hours. Especially widely used in medical, sauna, food heating and drying, etc.

B. Short wave infrared (also known as near-infrared) has the characteristic of 1-3 seconds of heating and cooling time, making the heating process control more flexible. A highly efficient and durable gold coated reflective layer for single and twin tubes can achieve a radiation efficiency of over 96% and an ultra long service life, generally exceeding 5000 hours. Especially widely used for drying and curing high-speed printing equipment, it can quickly heat the surface of plastics, water, and other solvents, and has the characteristic of being quickly absorbed by water film to achieve drying effect.
