Functional Characteristics of SRW Type 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. No heat transfer medium is required, resulting in good thermal efficiency.
3. Local heating is possible, saving energy.
4. Provides a comfortable working environment.
5. Saves construction costs and space for the furnace body, and is easy to assemble, install, and maintain.
6. Clean heating process, no hot air required, no secondary pollution.
7. Easy temperature control, rapid heating, and relatively safe.
8. Low thermal inertia, no warm-up 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 closely arranged and the object is heated in a fixed manner, 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 significant, directional energy propagation. Energy transfer does not require an exchange medium and can even be transmitted in a vacuum. Infrared can be divided into short-wave, medium-wave, and long-wave according to wavelength.
