Technical Data: Comparison of Far Infrared Heaters and Near Infrared Heaters

Direct heating and indirect heating are the same in their state, but far-infrared heating is fundamentally different.

There are three forms of heating to provide heat to the heated object: direct (contact) heating represented by hot plates, indirect heating represented by hot air heating, and radiant heating represented by far infrared heaters. All can be considered surface heating. Heat is absorbed at the surface of the heated object and transmitted internally through thermal conduction. However, while direct heating and indirect heating have the same mode, far infrared heating is fundamentally different. 【Features】 [Far Infrared Heater] ○ The surface is made of ceramic materials. ○ When far infrared radiation ceramics are heated, they cause molecular vibrations and crystal lattice vibrations, emitting wavelengths of 3μ or more from the surface. ○ In contrast, the molecular vibrations of the heated object are at 3μ or more, so when it receives energy from the far infrared heater, thermal vibrations are excited. ○ The heating from the far infrared heater is efficiently absorbed and generates heat in organic materials like paints and plastics, as well as in polymers, and it is also very well absorbed by water, making it widely used for drying and curing. ○ The heat source for heating far infrared heaters is typically electric heaters using nichrome wire, but gas, steam, and oil are also used.
