The principle of radiant heating is the same as that of solar heat. Radiation is not heat but consists of electromagnetic waves, which as soon as they hit an object are converted into heat.
Infrared radiation is subdivided into three groups
• Short wave - Infrared A - 760 to 1400 nm.
• Medium wave - Infrared B - 1400 to 3000 nm.
• Long wave - Infrared C - 3000 to 10000 nm.
Short Wave Infrared
The advantage of short-wave infrared heaters is that they require virtually no warm-up time.
