We can distinguish the electromagnetic rays or waves emitted by infrared heating into three different groups aluminium infrapanel. This classification is made based on the wavelength, which can be short, medium and long. Short wave rays, which are also known as high frequency waves, are what produce red light when in operation.
Meanwhile, medium-wave rays heat up to 900 ºC, which is suitable, above all, for drying objects. As far as long waves are concerned, they are used for heating indoors, where a low level of heat is present, although a time of heating is needed. preheating.
However, for use as heating elements, we divide the different equipment as short wave or long wave.
