Elstein Infrared Radiars Top quality infrared technology products...millionfold proved The company Elstein-Werk was established in Northeim 195 as the only facry worldwide specialised in manufacturing ceramic infrared radiars. Even then infrared radiars have been developed on the basis of own patents and processes, whose design and quality have determined the state of the art standards this day. Through continuous pioneer work and further development of our products, technically and economically interesting fields of application have been and are still being developed for infrared heating. Today Elstein infrared radiars solve all kinds of heating and drying tasks. Together with the proven modular systems, heating areas with a high power density and selective energy application can be realised in the material be heated. The controllability of the heat output using modern digital temperature controllers and thyrisr switching units ensures optimum use of energy and therefore helps save operating costs and protect the environment. A wide range is available for the initial installation, modifications or for extending machines and plants, which is and can be adjusted the needs of the heating tasks or the drying process.

This emission and transmission of the electromagnetic waves is associated with the specific, directional transport of energy. The transmission of energy does not require a transport medium and is therefore also possible in a vacuum. Infrared radiars are classified according their wavelength maximum of the spectral radiant power in short, medium and long-wave radiars. In shortwave infrared radiars the maximum is less than 1.5 µm. Long-wave infrared radiars are those whose maximum lies above 3 µm. Between them are the medium-wave infrared radiars. Figure 3 shows the spectral power distribution of several typical radiars in these classes. In general, the higher the temperature of a radiar, the shorter the wavelength of the radiation. The power emitted depends on the temperature of the radiar and its surface. Figure 4 shows the spectral power distribution of Elstein s SHTS and HTS infrared radiars at different surface temperatures. As you can see, at the same temperature, the black SHTS emits considerably more than the white HTS. However, the positive influence of a black glaze only becomes noticeable after temperatures have exceeded 8 C. Figure 4 also shows that, due the radiation properties of the white glaze, the spectral radiant power of HTS radiars is virtually independent of the temperature. All materials have different radiation values, as they partly reflect the radiation or, as it is the case with glass, let it pass through. Figure 5, for example, shows the absorption of bright aluminium and ceramic. Aluminium only absorbs about 15 %, the rest is reflected. Ceramic on the other hand absorbs about 9 % of the radiation. As absorption and emission are based on the same physical causes in each body, it is clear that ceramic is ideally suited as a material for infrared radiars. The power emitted by a radiar roughly depends on the fourth power of the absolute temperature (cf. Figure 4). Therefore, infrared radiars are usually operated at temperatures from 3 C in order achieve good efficiencies. In practice it must also be taken in consideration that the heated material also emits infrared radiation. Therefore, only the difference between the respective radiant powers actually heats the material. Figure 5: Absorption of various materials Page 4

5 Basic Physics Absorption % Water Tile Apart from a few subtle differences, the absorption spectra of many materials in the medium and longwave infrared range are very similar (Figure 6). While metal oxides and mineral materials absorb consistently well from around 3 µm, plastics with small layer thicknesses show characteristic absorption bands. In these wavelength ranges the absorption of energy is particularly favourable. Radiation in the other wavelength ranges is reflected or transmitted. This is significant when heating thin plastic foils, whereby the addition of small amounts of pigments can considerably improve the absorption properties. In practice, Elstein infrared radiars have proven be particularly favourable for this application Plexiglass.2 mm PVC, hard.2 mm Aluminium Paper Metal oxide Polystyrene.4 mm Elstein infrared radiars emit over a broad wavelength range. It is therefore not necessary match the maximum absorption of the material be heated with the emission maximum of the radiar. Whether the energy is absorbed by the material at a wavelength of 3 µm or at 6 µm is not important. Important is that the material be heated has good absorption properties and the provision of the required heating power. When bright or polished metals are heated on the other hand the absorption is hardly noticeable. The infrared radiation is primarily reflected. The reflectance is determined by the electrical conductivity and the surface quality of the metal. Slight changes in the surface property, e.g. greater roughnesses, oxide coats (cf. Figure 6) or paint layers, also enable heating by infrared radiation in these cases. The use of infrared radiars for drying materials is particularly significant. As Figure 6 shows, water has a broad absorption spectrum in the medium longwave range. For this reason, drying and evaporation tasks can also be advantageously solved using Elstein infrared radiars. Elstein infrared radiars ideally fulfil the various requirements of practical situations, and not only with respect the high radiar emissivity but also the optimum wavelength range for heating appropriate for the material involved. The data sheets and the radiars themselves list the limit temperatures be observed. These limit temperatures should not be exceeded because it can damage the ceramic µm Figure 6: Spectral absorption of various materials Page 5

6 Application Examples Application examples for the use of Elstein infrared radiars: Figure 7: Thermoforming plant for boat hulls Figure 8: 3-D heating panel for laminating door trims - Heating plastic foils and sheets in thermoforming machines - Production of shrink foils and films - Gelling PVC pasty coats on fabrics - Heating GRP parts during production - Thermofixation of nylon and perlon threads - Activating glues and hot seal coats - Drying plastic emulsions - Heating laminated materials before punching - Drying raw and printed papers, cardboards and wallpapers - Drying skins, hides and paint sprayed leather - Quick-drying gummed papers - Drying and baking enamelled sheet metal parts - Baking on powder coatings - Drying glazes on ceramic tiles - Tempering glass - Drying washed glass - Soldering printed circuit boards - Pre-heating weld seams in pipe construction - Baking on sound insulating mats - Drying fireproof impregnations for illumination and decorative papers - Heating climatic chambers - Drying washed, dyed and dressed fabric - Baking on fluidised bed coatings - Drying glued wood or furniture pieces - Heating the paper mash before it is squeezed - Pre-heating plastic pipes for joining - Curing epoxy resins - Tempering injection mouldings - Drying raw bacco - Heating dragée masses - Baking and browning biscuits - Heating icing or chocolate frosting - Keeping meals warm - Heating processed cheese - Keeping outdoor switchgear cabinets dry - Accelerating chemical conversions - Therapeutic medical radiation - Infrared heated cabins (wellness cabins) This list could be continued ad infinitum. This is because almost all application, production, handling as well as refining processes involve drying or heating tasks, and these can be solved outstandingly well using Elstein infrared radiars.

7 Planning Guidelines Roller EBF Figure 1: Roller heating using the EBF system Sheet metal part Reflecting panels Figure 11: Radiation tunnel with several EBF systems BSI EBF Figure 12: Heating a continuous material using 2 BSI systems Universal power rail Terminal Terminal point Continuous material When planning an infrared heating plant or system, it is the properties of the material be heated, which primarily determine the power and treatment time required. The easiest and most reliable way determine the data concerned is carry out a trial. We are always pleased provide planning advice and if you wish can carry out heating trials for you. The choice of radiar initially depends on the geometric circumstances of the heating task. The HTS series is the best choice for the radiar type. The integrated thermal insulation, the fast thermal performance and the ability adjust the power via integrated thermocouples offer users optimum possibilities. If fast clock times or high material temperatures are required, the HSR and HLS series can be used. If a low overall height is required, FSF radiars can be used. For systems, the choice is between BSI, EBF and REF. The EBF system is particularly advantageous for solving line-shaped heating tasks and for building infrared heating areas with variable geometries (cf. Figure 1). The BSI system is ideal for building even or large IR heating areas. All systems can be used with both a one-sided and a double-sided arrangement. If two heating areas radiate each other, for safety reasons special attention must be paid compliance with the maximum permissible radiar temperatures. In operation, the EBF and the BSI system can reach housing temperatures of up around 25 C. Therefore, the user must plan in design measures prevent contact with the hot metal parts. Elstein infrared radiars do not have any dazzling effects. However we recommend screening off the sides of the heating areas with polished aluminium or stainless steel plates. This prevents unnecessary heating of parts outside the actual oven and improves energy utilisation. For stability reasons, EBF and BSI systems must not have any additional thermal insulation. When designing the industrial ovens, particular attention must be paid ensuring all parts can thermally expand. Large, stiff constructions are therefore disadvantageous. In this context the wiring material is also important. Copper cables can only be used for individual radiars with a low power. The standard are cables made from nickel with heat resistant insulation or rail wirings. Radiar Figure 13: Rail wiring Page 7

8 Radiation Distribution mm % mm Centre spacing Figure 14: Spatial radiation distribution Elstein infrared radiars are produced with all kinds of different dimensions and geometries. They are available with round, long, square, rectangular and even with hemi-sphere shapes. The spatial distribution of the diffuse energy radiated in all directions depends on the outer shape. Figure 14 shows the radiation distributions for two spacings of Elstein HTS/1, HTS/2 and HTS/4. Similar distributions also result for the other models. The intensity is determined by the respective surface temperature. At this point, please note that the curved shape of the FSR does not have any focussing effect with respect the radiation. const T Radiar P Radiar In plants with a large number of radiars, the radiation distributions of all the radiars overlap. If, for example, several radiars with the same power output are installed next each other in a machine, there is an increase in power in the middle of the material be heated, which is mostly unwanted (Figure 15). For uniform power density on the material be heated, the radiars near the edge must be run with higher power or a higher temperature than the middle radiars (Figure 16). Figure 15: Power at the material be heated with constant radiar power T Radiar Figure 16: Power at the material be heated with adjusted radiar power T Radiar P Material be heated P Radiar P Material be heated The small design of Elstein infrared radiars enables the user realise very different radiation distributions on the material be heated. As radiation energy occurring at a point is the sum of the energy from all the radiars it is sometimes difficult radiate narrow areas with a particularly intensive or weak radiation. In these cases considerable improvements can be achieved by using shiny metallic reflecr plates or shutters. Figure 17 shows examples of possible designs. One question often asked is whether additional thermal insulation is needed on the back side of the radiars. This thermal insulation only has a useful effect if the requirements for the uniformity of the radiation distribution on the material be heated are low. The thermal insulation causes heating of the inner radiars by the outer radiars of a heating area. In the most unfavourable case, the inner radiars can even become superfluous. The majority of the radiation areas are therefore not insulated. In addition, the modern HTS, SHTS and HSR series radiars already have integrated thermal insulation, which does not usually require any additional insulation.

9 Performance C HSR HTS FSR Elstein infrared radiars differ in their mechanical structure. For example, the HTS series radiars have integrated thermal insulation materials, so that compared the FSR series radiars, considerably reduced heating-up and cooling times are achieved (Figure 18). With the HSR series radiars the time performance was improved again by a facr of 3. 2 % min Figure 18: Heating-up and cooling performance HSR HTS FSR min Figure 19: Power in controlled operation In this context, please note that the heating-up and cooling performance of an infrared radiar can be more easily judged with the heat sensitivity of the skin rather than with the eye. For example, if a halogen spotlight is switched off, the light goes off in a flash. But the hot glass tube continues dissipate its sred heat surrounding area for several minutes in the form of infrared radiation. Infrared radiation is reflected, transmitted and absorbed. Depending on the used IR-radiation source and the properties of the material be heated the three effects arise in different proportions. The wanted effect, which heats the material is the absorption so that this part of radiation should be as high as possible. High parts of reflection and transmission cause a minor efficiency of the radiar. Figure 2 shows an example for three different radiation sources heating a transparent foil: the long-wave infrared radiation of the ceramic IRradiar has the highest efficiency. % Ceramic radiar Quartz radiar Halogen radiar Foil thickness mm The efficiency of Elstein infrared radiars can reach values over 8 % in radiation areas. Figure 21 shows the typical curves for various panel radiars. You can see that the HTS and FSR radiars achieve very good efficiency values even at lower radiar powers. The HTS is clearly better than the FSR, thanks its internal thermal insulation. The best efficiencies are achieved by the HSR radiars because due their special design they transfer the energy supplied almost without losses as infrared radiation the material be heated. Figure 2: Absorption in transparent foils % HSR HTS FSR When using Elstein infrared radiars, the limit temperatures given on each radiar must be noted and observed. If it is exceeded, the ceramic and heating conducr can be damaged. Equally, when installing the radiars ensure that the radiars are protected against knocks, impact, and moisture when cold. Due the fixed installation of the heating coil, the radiars can be operated in any position W Figure 21: Efficiencies dependent on the power Page 9

10 Power Adjustment Thermocouple Thermal insulation Heating coil Elstein infrared radiars are available with varying power levels. The HTS for example has power levels ranging from 25 W 1 W. In practice however powers different these are mostly required. There are three ways of adjusting the radiar power the power requirements of the material be heated. The most simple way is change the distance between the radiar and the material be heated. This is only recommended if individual radiars are used. The second way is power control, for example using proprietary dimmers, like those used for lighting purposes. Figure 22: Thermocouple bedding The third and best way is adjust the power via temperature control using radiars with an integrated thermocouple. In Elstein s infrared radiars with thermocouple, the thermocouple is located between the radiating surface and the heating coil (Figure 22). Temperature controller Thermo line Radiar with thermocouple Control cable Radiar Fuse Thyrisr switching unit Radiar Mains Figure 23: Block diagram of the temperature control circuit The thermocouple signal is passed via a special thermo line, for example the input of the Elstein TRD 1 digital temperature controller (Figure 23). The temperature controller switches individual or whole groups of radiars on and off with the help of one or several Elstein TSE thyrisr switching units. An average power sets in at the radiars, depending on the length of time they are switched on. An URG superagile fuse is fitted upstream of the thyrisr switching units protect them against short circuits. This method enables compliance with the prescribed radiar temperature with an accuracy of one degree and thus enables the production conditions be reproduced. It can also be modified so that the temperature of the material be heated is measured. However, this requires reliable recording of the temperature of the material be heated. In most cases it suffices control the radiar temperature. By using several controllers, zones can be formed in the heating areas, for example, specifically heat certain areas of the product more strongly or weakly. Annular heating zones are frequently realised for large heating areas in order uniformly heat up the material be heated from the boundary area through the middle (Figure 24). Special programmable controls can also be used instead of a controller. Here it must be noted that the inputs for the thermocouples must be floating. Figure 24: Heating area with 3 heating zones Page 1

11 General Information Many Elstein infrared radiars have a standard socket, with which they can be easily mounted on a reflecr sheet (Figure 25). The radiars leads have defined standard lengths, but it is also possible manufacture radiars with longer leads. The lenght can be chosen almost at will but it should not exceed mm, because then the electrical safety is no longer guaranteed. For lengths over mm our manufacturer s liability expires. Figure 25: Fixing of Elstein radiars with socket a reflecting metal sheet Due the thermal expansion, when designing plant or systems you must ensure that the infrared radiars have adequate space. In general, a distance of 3 mm should be available between adjacent infrared radiars. The installed dimensions be observed are given in the data sheets for Elstein infrared radiars. The service life of infrared radiars depends on the use conditions and the radiar operating temperatures. The following table contains details of the service life of Elstein radiars (23 V) when operated under normal conditions: at C approx. 2. hours (e.g. FSR 25 W) at 7 C approx. 1. hours (e.g. FSR 1 W) at 9 C approx. 8. hours (e.g. HTS 1 W) at 11 C approx. 2. hours (e.g. HLS 75 W) Figure 26: Roller heating Unfavourable use conditions or incorrect radiar use can reduce the service life. Details of this are given in the safety instructions of this document. Negative influencing facrs with respect service life are, for example, chemical contaminations (chlorine, fluorine, hydrofluoric acid, caustic soda, nitrogen or peroxide), excessive mechanical loads or stresses, overheating and overvoltage (surge). As a standard Elstein infrared radiars are designed for 23 V. Sometimes however, cusmers want or need use other operating voltages. Most Elstein infrared radiars can also be supplied with other voltages. Operating voltages above 27 V, however require thinner heating conducrs than usual. The consequence is a lower durability under the same operating conditions. Except for under atmospheric conditions, Elstein infrared radiars are also used in vacuums. They are however not available in an explosion-proof version. Nevertheless, there are ways reach solutions, which enable Elstein infrared radiars be used. We will be pleased advise you if you have corresponding heating tasks. Figure 27: Heating area heat up the botms of bottles Page 11

12 Safety Instructions Improper use of electrically operated infrared radiars can, under unfavourable circumstances, result in fire or electric shock. This in turn can cause personal injuries and/or damage or even destruction of machines. For this reason the system builder and user must check whether the radiars are suitable for the respective application. The safety aspect must always be taken in account when selecting, installing and using the radiars. Our technical consultants will be pleased answer any questions you may have concerning this issue. Each delivery of our products is accompanied by relevant operating and installation instructions. These must be read and undersod before putting the corresponding product in service. In the event of damage caused by failure follow the instructions, the warranty claims and our liability for resulting consequential damages expire. The installation, electrical connection and putting in service must be carried out by appropriately qualified personnel. The national safety requirements of the country, in which the products are used, must be taken in account. These are, amongst other things, IEC, EN, VDE, UL and NEC standards. The following points must be noted when using our products (radiars and accessories): Installation/assembly of the infrared radiars 1) Do not install until you have read and undersod the installation instructions first. 2) Replacement of radiars and accessories may only be carried out after disconnecting all the system s poles from the electrical system. 3) The radiars must be installed at a safe distance from materials and living things ensure no fire or damage can ensue. 4) Radiars with E27 screwed bases may only be used in porcelain sockets or metal sockets with a porcelain insert. Operating the infrared radiars 5) The radiars must be operated so that they cannot be uched by the operating personnel or users. If necessary, warnings are be attached in the personnel or user s language. 6) The radiars may only be operated up the maximum allowable temperature stamped on the radiars. 7) It is advisable operate the radiars with a temperature controller (thermostat) avoid impermissibly high temperatures (see page 1 Power adjustment ). Radiars with a power from 6 W should always be installed with controlled operation. Radiar type HLS must always be used with temperature control. 8) Use of a power control is possible. However, for safety reasons, preference is be given temperature control with the help of thermocouple radiars. 9) It must be taken in account that when materials containing solvents are heated (paints, glues, etc.) they emit solvent vapours. The vapours can form a combustible air - gas mixture. This also applies a high level of dust in air. Therefore, for example, the Explosion Protection Directive (Article 51 National Electrical Code NEC in USA) must be taken in account. 1) After they are switched off the radiars still have residual heat. This can cause burns if the radiars are uched. Sensitive heated materials or objects can be damaged. Handling ceramic infrared radiars 11) The radiars must be protected against knocks, impact and damp. 12) If radiars come in contact with water, e.g. when cleaning the system, they must be immediately dried by briefly heating them. 13) Damaged radiars must be replaced immediately. Notes on equipment and system building 14) The electrical and mechanical accessories for setting up a radiation system must be designed so that they withstand the thermal, electrical and mechanical stresses. 15) It is always advisable install equipment which switches off the infrared radiars, e.g. in the event of faults in the system. Such equipment may be absolutely necessary where the radiars are used heat sensitive or easily combustible materials or living beings. The decision and responsibility for their installation lies with the system builder. 16) The system builder must note and observe the relevant standards and regulations for installation and operation of the radiars depending on their use. This especially applies equipment and systems used for heating people or animals (for example, medical, therapeutic or wellness equipment). The manufacturer of the complete equipment/appliance is responsible for compliance with the regulations. Page 12
