Technology - STIR®-heater are more efficient!

STIR® is more effective in comparison to the conventional thermal conditioning methods for coatings (lacquer), among adhesive-conditioning with convection heat and classic infrared, because the absorbance of the chemical molecules in the product are nearly conform to the emission spectrum of STIR®. So that the heating and hardening can be fasten, compared to the actual methods using, without compromising on quality.

Therefore the processing time, processing room and energy effort can be optimized.

STIR®-heater are more efficient!

One of the most important facts for the user is the energy efficiency. This is defined by the effectiveness and describes the relation between input and output of power respectively energy. In the case of infrared heaters the efficiency of the radiated power is the determining factor.

The company IBT InfraBioTech GmbH has had measurements performed by KIT - Karlsruher Institut für Technologie. They have been measured different STIR®-heaters in comparison to other commercially available ir-heater. In the graphic below is shown: STIR®-heater are more efficient!

The STIR®-ceramics heater has a 7% higher effectiveness in comparison to a conventional ceramics heater, the STIR®-IRQ-heater is in comparison to a commercially available quartz heater (light emitter) with 22% effectiveness  even more efficient. We got the same result by comparison to the average effectiveness of a gas-powered dark heater. The high efficiency of the STIR®-infrared fields (module) deserves special mention.


In the diagram are shown significant differences between the conventional ceramics-, quartz- and baking oven emitters and the STIR® emitters. This tests have turned out an emission factor of 92% in case of the quartz emitter compared to commercially available light emitters with 39%, at a wavelength of 3 microns. The comparison of ceramics- and baking oven emitters turned out significantly for the benefit of of the STIR® infrared emitters as well. Thus they are perfectly suitable for the use in drying processes. With STIR®-heaters the energy emitted is absorbed in the resonance range in the radiated goods and therewith are more effective in the thermal treatment of materials compared to convection heat an classic infrared.

The applied research methods have shown that an improvement in the effectiveness of technological processes can be made by a more efficient energy transfer by using the special infrared STIR®. For the user of infrared technology this brings the benefit of a reduction of operating and energy costs.
