Infrared and Radiant Heating. Infrared heating is the transfer of energy via electromagnetic radiation between a source and an object. Most materials absorb heat in the infrared wave band with useful wavelengths for industrial applications in the 3 to 8 micron ranges. Radiant heating (electric, gas, steam, oil) is often used for drying textiles, ceramics, paint (wood and metal), hardening powder paint and heat treatment of plastics.
