The heating zone and keep zone can be easily set, allowing for continuous transport heating.

The absorption wavelength of coatings and heated plastics (excluding metals) is over 3μ. The radiation wavelength of far-infrared heaters is also over 3μ. Therefore, since they are both absorbers and radiators at wavelengths over 3μ, they are very efficient for heating. In other words, most of the energy is absorbed at the surface of the object. 【Features】 - The heater temperature can be freely adjusted. - The heating and holding zones can be easily set, allowing for continuous conveyor heating. - The temperature distribution of the heated object can be made uniform, leading to improved quality. - Due to high efficiency, it results in a space-saving (compact) device.

basic information

**About Far Infrared Heating Method** ■ Near Infrared Heating… ○ The radiation wavelength of near infrared heating is usually less than 2μ. ○ Temperature control is difficult. ○ It is inefficient because it does not match the absorber of the heated object, resulting in large equipment and high power consumption. ○ Heating efficiency varies depending on the color of the heated object. ○ It is advantageous for heating that requires high power due to its high temperature. ■ Hot Air Heating… ○ In hot air heating, the temperature of the hot air is set to be the same as the temperature of the object to be heated. ○ The heated object will stop absorbing heat once its surface temperature matches the hot air temperature. ○ It will absorb heat only to the extent that heat has moved internally. ○ The surface of the heated object rapidly approaches the hot air temperature immediately after contact with the hot air, while the heat flow into the interior decreases, causing the temperature rise to take longer. ○ Therefore, if the heating time is short, the heat flow into the interior is limited, resulting in a large temperature difference between the surface and the interior of the object. ○ However, even if the heating time is exceeded, the object temperature will not rise above the hot air temperature, making it a safe heating method. ● For more details, please contact us or download the catalog.
