Radiant heat — A full-fledged industrial tool

Although the great majority of commercial heat sources deliver an appreciable portion of their energy in the infrared spectrum, most industrial heating processes now rely on heat transfer by convection. With the intermediate heating of the air between the source and the point of useful work, two or more energy transfers result with consequent loss in speed of transfer and efficiency while the available radiant energy is largely converted into convected heat by the heat transfer system before it is usefully employed.
