There are those out there when they hear Infrared technology, they immediately think military and NASA/DARPA technology. This isn’t the case. Infrared Technology is used in many Industrial Heating (IR) applications across several different industries. It’s not always lasers and spaceships. IR has many applications when it comes to heating such as high temperatures and preheating. To help you understand we need to go over some basics in physics. More specifically Radiant heat and Infrared heat.
Radiant Heat is transmitted through electromagnetic waves. When the waves are absorbed they are converted into heat. A perfect example of this is the sun. When infrared waves touch a surface, heat energy is released regardless of the surrounding air temperature. The radiant energy (heat) is absorbed by objects all around; Trees, rocks, cars, grass, you, me; all absorb radiant energy from the sun and convert it to heat energy. In an industrial application, this is very beneficial when you need to avoid direct physical contact or are trying to avoid contamination of a product.
Radiant VS Infrared
Wait, aren’t they the same thing? Well, yes and no. It all boils down to temperature. Both are from an infrared radiant energy source. Stay with me here, the shorter the electromagnetic wave length the higher the heat source. The longer the wave length the lower the heat source. Longer wave lengths have lower temperatures around 150 degrees F; and shorter wave lengths have higher temperatures around 1000 degrees F +. Confusing isn’t it? Not really, if you think about it like a rubber band. Stretch the rubber band over the back of a chair. Pinch it in the middle and pluck it like a guitar string. The tone made becomes ‘higher’ the shorter your finger placement and ‘lower’ the longer your placement. Who knew that childhood music games could be applied to physics? Finish the article and you can try it later.
Infrared heating is typically used outdoors or for spot heating in unheated areas. A workbench, loading dock, melting icy sidewalks etc…
Radiant heating is typically used for places like offices or areas where forced air heating isn’t prudent due to space/size constraints. I have a space heater under my desk doing exactly that right now. My feet are nice and toasty.
Radiant heaters are more efficient because their electromagnetic waves are intercepted and converted into heat by the person or object. (Hence the reason I have a heater under my desk right now.) Compare this to convection systems that have to heat all the air in a room. Hot air rises and a good portion of the heat is lost. Radiant heaters focus their heat much like light does which increases the adaptability in different configurations. Radiant heaters are also more efficient because it takes much less time to get to operating temperatures.
