The characteristics of far-infrared electric heating tubes

The characteristics of far-infrared electric heating tubes

1. Control the wavelength between 0.76-25 μ Approximately m infrared radiation, users can choose heating tubes of different wavelengths based on the material and physical characteristics of the heated workpiece, or choose heating tubes of different wavelengths to form the best combination scheme.

The thermal efficiency of the heating tube is very high, with an infrared radiation efficiency of over 86% at a certain wavelength and direction.

3. The thermal inertia of the infrared radiation heating tube is extremely small, and it can reach about 50% of the rated power in 1-2 seconds after being powered on. It can run at full power after about 2-4 seconds, and the heating and cooling process is rapid and accurate.

4. The heating tube itself has a small volume but a high power. The rated power of a single heating tube can reach over 6000W, making it easy to make far-infrared heating equipment such as plate heaters, hot air heaters, ovens, and drying channels.

5. According to customer needs, a directional reflective layer containing precious metals such as gold and titanium or oxides such as zirconium and aluminum can be sprayed on a certain part of the outer wall of the heating tube, which can greatly improve heating efficiency and reduce the temperature of the reflective plate.

6. Heating tubes have low cost and long service life. Heating tubes below 2000W have a continuous service life of over 5000 hours under rated conditions, while heating tubes above 3000W have a service life of over 3000 hours, which can greatly reduce operating costs.

7. Various heating devices composed of infrared radiation heating tubes can achieve automatic temperature control through temperature controllers, thyristor AC power regulators, or voltage regulators. Due to its small thermal inertia, temperature control is fast and accurate.

8. Power ranges from 30W to 6000W, voltage ranges from 36V, 110V, 220V to 380V, length ranges from 60mm to 3000mm, and shapes include single hole tubes, double hole tubes, Ω - shaped tubes, and irregular tubes. Various specifications of amorphous tubes can be produced according to user needs.

Due to high-energy and high-density radiation, the time required for heating work and the length of the drying channel are greatly reduced, saving space occupied by equipment and directly reducing user investment in equipment and factory buildings. Meanwhile, due to its high thermal efficiency, it can greatly save electricity and reduce production costs.

In recent years, the advantages of far-infrared radiation heating technology have gradually been recognized, and the manufacturing level of infrared radiation heating tubes is increasing. Its application scope in various industries in China is becoming increasingly widespread. Suitable for almost any industry that requires heating: painting, printing and dyeing, food, electronics, medicine, textile, wood, paper, automotive, plastic, furniture, footwear, metal, heat treatment, packaging machinery, heating, and so on.
