Features of SRW Far-Infrared Heater
Infrared drying and heating methods have been accepted and applied in various fields at an astonishing rate in recent years, mainly because infrared heating has the following advantages:
1. It has penetrating power and can heat both inside and outside simultaneously.
2. It does not require a heat transfer medium, resulting in good thermal efficiency.
3. It can provide localized heating, saving energy.
4. It provides a comfortable working environment.
5. It saves on furnace construction costs and space, and is easy to assemble, install, and maintain.
6. It is a clean heating process, requiring no hot air and producing no secondary pollution.
7. Temperature control is easy, and heating is rapid, with higher safety.
8. Low thermal inertia, no warm-up time needed, saving labor.
Because infrared heating has the above advantages, it is possible to achieve heating with high yield and uniformity, thereby obtaining high-quality products.
Working Distance
For heat-sensitive materials (such as paper or thin sheets), the working distance should be greater than or equal to 50 mm. If the heaters are not arranged densely and the heated object is fixed, the working distance should be appropriately increased. If the heater spacing is 2-3 cm, a working distance of about 20 cm can achieve uniform heating.
Basic Theory:
Infrared radiation refers to the emission and transmission (propagation) of electromagnetic waves in the spectrum between 0.7um and 80um. The emission and transmission are accompanied by obvious, directional energy propagation. The energy transfer does not require a medium and can even be transmitted in a vacuum. Infrared can be divided into short-wave, medium-wave, and long-wave according to wavelength.
