Energy-Saving Direct Heating via Infrared Radiation!
Far-infrared radiant ceramic heaters are once again attracting attention for their energy-saving and power-efficient performance.
Radiant heating offers faster temperature rise compared to convection or conduction heating, and minimizes heat loss to surrounding air or containers.
Far-Infrared Radiant Ceramic Heater
-
Nishimura Advanced Ceramics’ far-infrared radiant ceramic heaters, models N-370 and N-370B, are effectively used for heating and drying applications.
-
The far-infrared radiation emitted from our ceramic heaters is well absorbed by common materials, enabling highly efficient heating.
-
Model N-370B is designed to enhance emission in the near-infrared range, making it suitable for room heating and food preparation.
Materials that Readily Absorb Far-Infrared Radiation
(Absorption wavelength range: 2–30 μm)
- Living organisms including the human body
- Polymers such as plastics, textiles, rubber, and paints
- Food components like proteins, starches, and sugars
- Organic and inorganic molecules including water and alcohol
- Crystalline substances such as ceramics, salt, and ice
