Our heaters produce a dark infrared which, depending on the application, is adjusted to the absorption of water molecules of CH- and OH-groups in goods. It is qualified e. g. for lacquer drying, for plastics processing, for construction drying and baking as well as drying of fruits and other foodstuffs.
The emitted energy is absorbed in the area of resonance in the irradiated goods. STIR® is much more effective in comparison to conventional methods of thermal treatment of raw materials like convection heat or classic infrared, as the energy transfer is mainly taking place in the part of resonance.
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.
