All hot materials radiate energy. Energy is transferred in line of sight by electromagnetic waves, emitted by the source (hot surface) and absorbed by the sink, i.e. the cooler surface. The amount of radiant energy transferred depends on temperature, emissivity and the effective surface area of the source and sink.

Heaters, which utilize radiant energy to transfer heat, are commonly known as infrared radiant heaters. Radiant energy is absorbed into the surface layer of material being heated and then dispersed through the material by conduction. Before you dry, heat, bake or cure any product with any heat source check Akinsun quartz heater features.

Standard quartz heaters have a response time of 80% within 15 seconds and 100% within 30 seconds � with almost the same cooling time. These heaters are quiet, cool and emit no significant glare. Infrared heat waves are absorbed by both light and dark color surfaces at the same speed. Special heaters can be designed for response times quicker than 15 seconds.
