Shortwave Infrared Quartz Heating elements| Heater Bulb | tungsten Halogen Lamp

Shortwave quartz heating elements|halogen lamp, also known as halogen heating tube: tungsten wire with bracket ring (temperature resistance up to 3400oC) is used. As a radiator, it is enclosed in a quartz glass shell. The color temperature is 2400-3500K. The wavelength range is 0.8-1.8 micrometer, peak at 1.2 micrometer. Turn on or off quickly, heat up quickly (The reaction time from start-up to the highest temperature is about 1-2 seconds), which is characterized by strong radiation, high penetration, high flexibility and convenient installation, high temperature resistant, suitable for high-speed production and occasions that require rapid preheating, such as automobile manufacturing, textiles, plastics, spraying, papermaking, printing, inks, adhesives, solar photovoltaic, etc.
The tungsten wire in the middle is classified into two types: white and black (since the cost of white tungsten wire is much higher than that of black tungsten wire, it is not popular on the market).

We can process halogen heating lamp into various shapes (ring, pear-shaped), U-shape, C-shape and straight tube.
To improve the reflection efficiency, the quartz tube can be semi-plated with gold or whitened (ceramic reflective layer). The surface of the quartz tube can also be sanded to reduce the brightness. It is widely used in various Small Appliances, such as Electric Heaters, Yale stoves, electric stoves, coffee makers, beauticians, ovens, etc.

Performance Of Shortwave Quartz Halogen Heating Lamp

1、Halogen has stable electrical performance, stable electric heating power, fast heating, and high electric heating conversion rate of up to 85%.
2、The surface temperature heats up rapidly (can be emitted to 100% within a few seconds), which is more energy-saving than ordinary traditional metal materials by more than 20%. The efficiency of electric heating installation and replacement is as high as (85%), the energy-saving is significant.
3、The thermal radiation of infrared rays is highly directional. Therefore, the direction of thermal radiation can be designed.
4、 The switching on and off of the lamp tube during usage will not affect the service life of the lamp tube, but the timed cooling can also make the quality of the heating tube better restore its life. The installation and service life are guaranteed at normal temperatures to more than 2 years.

Advantages Of Shortwave Quartz Halogen Heating Lamp

The short-wave infrared halogen heating tube adopts tungsten wire tube, which has a low heat capacity. After the equipment is switched on, it can reach to 80% of the energy output within milliseconds, to 100% within a few seconds. Similarly, after the production line is shut down or when the coated product is switched to a non-coated product, the energy output can be stopped instantly. Therefore, it has a high thermal response speed, which ensures that the system can be ready once turned on and shut down immediately once turned off. This can avoid inefficient energy output / wastage.
Whether infrared heating is effective depends mainly on the level of absorption of the heated object. The higher the absorption rate, the better the effect of infrared radiation. The actual absorption rate of an object depends on its own situation and the wavelength distribution of infrared rays. That is, when temperature rises, the peak wavelength will move in the direction of short wavelengths. The specific conditions of the absorbent object include the absorbent type, surface temperature, surface roughness, and degree of selective absorption of monochromatic radiation. In the production process, it is also necessary to consider the surface coating state of the heated equipment, the response time of the radiation element, the initial temperature required for work, space conditions and power supply conditions.
Shortwave infrared heating technology has the characteristics of high efficiency, cleanliness, Safety, high control accuracy, small footprint and easy operation and maintenance. Therefore, for enterprises with rich power resources and lack of gas, shortwave infrared heating technology should obviously be the first choice in heating and drying the ordinary products. For the transformation of the old machinery with narrow air access, the shortwave infrared heating technology can better reflect the merits of being “instantly on-line”.
