IR heating elements are used for an endless number of heating and drying applications. A selection of IR heating and drying applications has been placed on our Website under applications. For determining if electric heating elements can be used for your application we provide consulting and test devices. If required we can do heating and drying tests in our laboratory, too.

Electric IR emitters provide only the non-visible infrared radiation and no visible or rather hardly visible light. The emitted infrared radiation covers the medium and long-wave infrared range of 2 – 10 µm

Yes. For decades IR radiant heaters have been used in clean rooms class 100 or better. They are used in semiconductor production, in the pharmaceutical industry and in manufacturing picture tubes. Infrared Radiators are also used in the production of modern TFT displays.

In the case of heat-sensitive goods (paper, thin foils) the radiation distance should not be less than 50 mm. If the radiators are not mounted densely next to each other, the distance must be larger if the goods to be heated are stationary. If the distance between radiators is 3 – 4 cm, a distance between radiators and goods of 15 – 20 cm is required in order to achieve uniform heating.

Bright metal shows a relatively weak absorption of infrared radiation. However, corroded, roughened, coated, enameled or painted metal can reach an absorption degree of more than 90%.

When hot, infrared emitters are splash resistant. If the radiators get in touch with water when they are cold, they must subsequently dry at a low temperature (max. 80°C) for a few minutes.
