- Resonance effect (maximum utilization of the absorption band of molecule groups, coordination with coating and temperature, selectivity)
- Energy field and temperature range: selection of the optimal emitter temperatures from 100 to 700 °C (to 5W/ cm²), λmax. = f (δ) and material-specific irradiation
- Combination options: medium (quartz SiO₂, ceramics Al₂O₃, steel, epoxy resin)-coatings – primary energy sources (electro technological-NiCr-heating wires, gas)
- Duplex- and spatial effect: if the irradiation is not completely absorbed in the processing room, it is available on opposing surfaces.
- Reflector effect: the reflectors installed on the emitter assure the optimal irradiation process by calculated geometry
- Unique position due to the functional ceramics coating of the emitters
- Long life period of the heater according to small thermal forces onto the substrate
- All thicknesses of substrates consisting of plastics, timber or metal is possible
- The thickness of coatings should not exceed 150 µm
- Power density on the irradiated surface of 2 - 50 kW/m² ispossible
- Reduction of operating- and energy costs according to shorter processing times on smaller demands for processing room, variable zone controls and power input
- Client-specific solutions for better processing quality
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.
