Infrared Modules Type IRD - Overview Due to its compact design, the OPTRON IRD module serie is ideally suited for drying and heating e.g. for running paths in the near of the irradiation area. With continous IR emitter for applications with short irradiation distances. Regarding the energy irradiation of a IR emitter in axial direction appeared an almost homogenous irradiation at short distances (see diagram). At longer distances, the IR energy will be reduced at the fringes. Shorter irradiation distances will also raise the efficiency due to reduced reflection losses. Especially at drying processes the constructive buildup of the IR module offers an additional important advantage. Through the light and pointed front-sided air turbulence over the whole module width, the drying process will additional accelerated by the removal of the arising solvents. IR emitter assembly The IRD-modules can be assembled with various IR emitters of our product line. All modules are available with shortwave emitters. If it is possible to assemble the modules with fast medium wave, fast medium wave type C or NIR-emitters you'll find the device on the following pages. For further information of the different IR-emitters read our corresponding data sheet. Spectral energy distribution of various Optron IR emitters Maximum spectral emission of shortwave IR-emitters is around 1.2µm. This spectral region has proven perfectly suited for heating solid materials, because the IR energy penetrates deep into the material and ensures an even distribution of heat. The maximum spectral emission of the fast medium wave emitters is around 1.6µm. The advantage is a higher energie absorption of partly or total transparent materials. The depth of penetration is a little bit lesser as with shortwave IR-emitters. The maximum spectral emission of the fast medium wave type C emitters is around 2µm. The performance of this irradiation is more effective on most plastics and aqueous solutions than shortwave irradiation. But with decreasing depth of penetration. Response time is approx. 2 seconds. The fast medium wave type C emitters are a new development and replace the previous carbon emitters ! The maximum spectral emission of the medium wave IR-emitters is around 2.6µm. Medium wave IR-emitters are favoured for heating of plastics or aqueous solutions because energy with this wavelength is better absorped. The maximum spectral emission of the NIR-emitters is around 0.98µm with the advantage of max. penetration and high emittance.

Infrared ModulesType IRD - Overview Apposition of IR-Modules Shortwave IR-emitters are normally bar-shaped radiation sources with relative small filament surfaces and high power density. The energy allocation off the target area can easily reached by changing the irradiation distance. By using several IR-modules an almost homogeneous irradiation area in every size can be build up. twin emitter distance for an almost homogenous product irradiation D = emitter distance to product All pictures are approximations Documentation last updated: 11.06.2013-30 OPTRON GMBH • Steinriede 12 • D-30827...
