FAQ - frequently asked questions

What is infrared?

Every medium, unless its temperature, releases energy in form of irradiation. According to technical relevance we talk about infrared (short: IR), if the temperature of the irradiating medium lies in a spectrum of approx. 100 to approx. 1.000°C. This energy is part of the electromagnetic total energy that encloses us.

What causes infrared?

If the infrared-irradiation, unless through vacuum or gas filled space, impinges on liquid or solid material it will be absorbed and reflected on the material surface. Generally it causes the heating by vibrations according to the substance-specific absorption. The gas molecules between heater and object are heating up as well.

When is infrared beneficial?

Firstly it is beneficial to use infrared, if the energy demand by convection could no longer be transmitted in the required time period. Secondly, if technologies like microwaves, high frequency emitters or electron beams heat up undesirable areas. And thirdly, if UV-irradiation could not be used (or do not find a “resonance partner”).

What means short-, medium- and long-waved IR?

Regarding this, there are no definite specifications given from technical literature or emitter manufacturers. Short-waved IR-heaters always emits a percentage of visible light. Medium-waved heaters generally keep their “cold”-color and emit at a temperature between 200 and 600°C. Long-waved heaters, which are lying under 200°C, are rarely used for industrial applications.

To which area do the IBT-emitters rank among?

It ranks definitely among the medium-waved (dark-) emitters. Our special infrared STIR® thereby lies in the spectrum of 2-10 µm. (see illustration)

Do middle-wave emitters have „depth effect“?

Not directly. This wavelength spectrum absorbs almost exclusively on the solid part surface or on the heated coating. Only the heat conduction of the heated barriers in the core of the substrate causes the core heating.

Is infrared energy efficient?

Yes, around the emitter and the object can be constructed the smallest possible workspace by IR-reflected areas with a low insulation effort. All secondary energy forms of the consumed primary electrical energy are usable.

Is infrared dangerous?

No. Electrical infrared is used for heat therapy for a long time. The sun or fire are deemed as natural sources of infrared. The infrared ratio of the solar radiation, that reaches the ground, accounts for approx. 50%.  The complete radiation protection for industrial machines serves as a benefit for saving operating costs by using within the radiation space.

What are profitable applications for IR?

This includes all processes with mandatory contact free energy input. (A hot-air-convection might force too big flow forces.) Also all processes of evaporation and chemical cross-linking, especially in the range of medium-waved emitters from 3-14 µm.

What does the distance between emitter and object mean?

Due to emitting into the three-dimensional room, the emittance decreases quadratically on the impinged medium. Therefore collateral “loss”-irradiation needs to be reflected to its destination or needs to be avoided by focused reflectors. Water vapor as a good absorber should be conveyed for watery drying topics.
