Quartz Infrared Heaters

Infrared Heating Lamps | Infrared quartz heater| Halogen heaters

Infrared lamps, also known as infrared heat lamps, refer to lamps with the main radiation components in the infrared spectrum. Infrared lamps can provide controlled energy radiation, can be used for heating, are mainly used in semiconductor industry in thermal electronic wafers, PETP bottle blowing, reflow soldering equipment, drying fillers, drying paint in motor vehicle repair, medical mainly used in the color positioning of photocopiers,  Bottom plate welding fusion of printing circuit, heating and disinfection of food, machinery, automobile, food, medicine and other industries.

How infrared heating lamps work

Infrared quartz heaters are made of tungsten wire stretched into an inflated quartz tube. The tungsten wire heats up and heats the gas in the quartz tube under the action of AC voltage, resulting in infrared electromagnetic waves. Infrared radiation radiates outward and can be used for heating.

Quartz, near-infrared, and far-infrared use clear or translucent quartz glass, as the lamp housing can produce near-infrared or far-infrared radiation spectrum. Infrared is a type of electrical wave, which travels at the speed of light and carries high energy, and the radiation intensity of different types of infrared rays of the same power is different with different wavelengths.

Longwave infrared (i.e., far-infrared) has the following characteristics: fast heating speed, uniform heating, small thermal inertia, constant temperature time of components of only 1-3 minutes, high-power radiation conversion efficiency from 60% to 75%, explosion-free cold and heat, energy saving, and long service life. 

Shortwave infrared (i.e., near-infrared) has the characteristics of a heating and cooling time of 1 to 3 seconds, making the control of the heating process more flexible. Durable gold-coated reflective layer for single Li tube and tube, radiation efficiency and service life usually more than 5000 hours. It is especially used in drying and curing high-speed printing equipment, which can heat the surface of plastics, water and other solvents, and has the characteristics of being absorbed by the water film and drying effect. Such as Heidelberg, Roland, Komori, Liubi and other offset printing machines; McAndy, Gelas, Yajiafa and other flexographic printing machines; Hardcover book link production line equipment, such as Martini, Corbus hardcover link line, etc.

Characteristics of quartz heaters

The infrared heating tube is a tubular heater that uses the principle of infrared light. It has the characteristics of excellent quality, high thermal efficiency, high power density, fast heating, energy saving, long service life, etc., and is an energy-saving heating technology that developed rapidly in the 80s, and has been listed as a key promotion project in our country, and has achieved rewarding economic benefits. 

Infrared is widely used in industrial heating or drying, such as automobiles, plastics, printing, glass, textiles, food, metal parts, circuit board packaging, electronic films and fields, and other surface heating drying and curing processes. 

Quartz, near-infrared, and far-infrared use clear or translucent  quartz glass, as the lamp housing can produce near-infrared or far-infrared radiation spectrum. Infrared is an electromagnetic wave that travels at the speed of light and carries high energy, and the intensity of radiation and the wavelength of different models of infrared rays of the same power are different. 

A. Long-wave infrared (i.e., far-infrared) Its characteristics: fast heating speed, uniform heating, small thermal inertia, only 1-3 minutes to reach the constant temperature of the element, high-power radiation conversion efficiency of 60%-75%, cold and hot without explosion, energy saving and long service life. 

B. Shortwave infrared (i.e., near-infrared) Its features: It has a heating and cooling time of 1-3 seconds, which makes the control of the heating process more flexible. The efficient and durable gold-coated reflective layer of single tube and double tube can achieve radiation efficiency of more than 96% and long service life, usually more than 10,000 hours. It is especially used in the drying and curing of high-speed printing equipment, which can quickly heat the surface of plastics, water and other solvents, and can be quickly absorbed by the water film to achieve the drying effect. 

The energy-saving principle of infrared heating tube:

When far-infrared light passes through the quartz tube, it is reflected and refracted several times, resulting in a milky effect. It has excellent far-infrared radiation characteristics. If the back is sprayed with gold or half-coated with white alumina, the effect is better and the energy savings can be up to 35%. 

Properties of infrared heating tubes:

The infrared heating tube does not use paint on the outside, does not use fillers inside, has stable emissivity, does not deform at high temperature, no harmful radiation, does not pollute the environment, high corrosion resistance, good chemical stability, low thermal penetration, high thermal conversion rate, long-term use, and does not deteriorate its true color.
