About Far Infrared: What is Mid-Infrared?

Introduction to the classification of infrared heaters in Japan and Europe!

AMK Co., Ltd. is a company that handles industrial far-infrared heaters, heating devices, and drying devices. In Japan, organic materials and polymer substances have most of their infrared absorption in the long wavelength range of over 3μ, which is why heaters that emit wavelengths of 355μ or more are referred to as far-infrared heaters. The surface temperature of typical far-infrared heaters in Japan is around 600°C, and when compared to a black body, the peak wavelength is 3.3μ, with the radiation amount over 3μ accounting for more than 80% of the total. On the other hand, in Europe, when classifying existing infrared heaters, the peak wavelength of the radiation energy of a theoretical black body is referenced based on the temperature of the heating element. For a heater at 2000°C, the peak wavelength is 1.27μ, with radiation energy below 2μ being 57% and below 5.5μ being 90%. The peak wavelength of a heater at 1000°C is 2.28μ, with radiation energy between 2 and 4μ being 48%, which is why the former (below 2μ) is called a near-infrared heater and the latter (2 to 4μ) is referred to as a mid-infrared heater. *For more details, please refer to the catalog or feel free to contact us.*
