Conceptual Infrared Heat – The New MAX Infrared Oven for Efficient Industrial Solutions


Tempering of glass, enameling, coating of metals or the sintering of ceramics all require very high temperatures. Such heating processes need a lot of energy, time and space.

Heraeus Noblelight has developed a new infrared oven – MAX – for high temperature heating processes. These new ovens combine infrared radiation with convection and optimum reflection. As such, they are superior to conventional industrial ovens. They are matched exactly to the heating process, so making it very stable. This helps to increase capacity and improve quality and the efficient ovens save space, time and energy.

MAX – precisely tailored for maximum customer benefit

Juergen Weber, development project manager at Heraeus Noblelight, explains, “As they reach their maximum temperature within a very short time, the new MAX ovens flexibly meet customer requirements.’ The new oven can achieve a maximum product temperature of 900°C in less than ten minutes and can also cool down in less than ten minutes.This allows fast product change-over. The oven can also be used in both continuous and batch operation.

All MAX infrared ovens feature a compact construction, which utilizes the energy significantly more efficiently, because the infrared radiation is optimally reflected within the oven, which also uses natural convection. As a result, the process time can be reduced, significantly increasing energy efficiency and lowering operating costs. 

MAX Infrared ovens – extremely energy-efficient

MAX infrared ovens are currently used in Heraeus’ in-house application center for intensive trials on customer materials. “Coating metal plates or glass tempering are particularly energy-intensive processes creating enormous electricity costs,” continues Juergen Weber. “Our tests show that this new design of oven can save a third of this energy or more.” One of the ovens, with a heated length of 700mm and a chamber cross section of 150x150mm achieves the maximum emitter temperature in less than a minute when working in a continuous process. In constant operation at a holding temperature of 900°C, a holding power of around 3kW is all that is required because of the exceptional energy-efficiency. In addition, it has been shown that an extremely good homogeneity can be achieved with a temperature difference within the product of only +/- 2°C. 

Advantages of QRC® Material Over Standard Ovens

Tests demonstrate clear advantages over standard ovens, which use fireclay as the insulation material. In MAX infrared ovens quartz glass materials with QRC® nano-reflectors (QRC = quartz reflective coating) are used exclusively inside the oven. The QRC® reflector, developed by Heraeus, features opaque, white quartz glass. Its nanostructure imparts a diffuse reflective capability to the material, resulting in a very high homogeneity of the temperature field.

Quartz glass is extremely heat-resistant and widely resistant to the attack of acids and other aggressive substances. It has excellent mechanical stability, even at very high temperatures.

From simulation to final solution

MAX infrared ovens enable system solutions. Computer simulations at the design phase help to create an energy-efficient heating process. MAX oven elements can be arranged one after the other in modular fashion and individually controlled, allowing fast product change-over. In addition, the ovens can be easily connected with conveyor systems.

Infrared emitters can be precisely matched to product and process, saving energy and cost. Infrared heating should always be considered for heating processes which have important requirements in terms of space, time or quality. Heraeus offers infrared emitters, controllers and handling solutions to meet these requirements.

The precious metals and technology group Heraeus headquartered in Hanau, Germany, is a global, family company with over 160 years of tradition. Our businesses include precious metals, materials and technologies, sensors, biomaterials and medical products, quartz glass, and specialty lighting sources. With product revenues of € 4.2 billion and precious metal trading revenues of € 16 billion in 2012, Heraeus has around 12,200 employees in more than 100 companies worldwide and holds a leading position in its global markets. 

Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China and Australia, is one of the technology- and market-leaders in the production of specialist light sources. In 2012, Heraeus Noblelight had an annual turnover of 92.5 Million € and employed 715 people worldwide. The organisation develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical measurement techniques.

Heraeus Noblelight acquired the Fusion UV Systems Group, headquartered in Gaithersburg, Maryland, USA, on 31 January 2013.

Im Focus: Reliable in-line inspections of high-strength automotive body parts within seconds

Nondestructive material testing (NDT) is a fast and effective way to analyze the quality of a product during the manufacturing process. Because defective materials can lead to malfunctioning finished products, NDT is an essential quality assurance measure, especially in the manufacture of safety-critical components such as automotive B-pillars. NDT examines the quality without damaging the component or modifying the surface of the material. At this year's Blechexpo trade fair in Stuttgart, Fraunhofer IZFP will have an exhibit that demonstrates the nondestructive testing of high-strength automotive body parts using 3MA. The measurement results are available in a matter of seconds.

To minimize vehicle weight and fuel consumption while providing the highest level of crash safety, automotive bodies are reinforced with elements made from...

Im Focus: Kick-off for a new era of precision astronomy

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.

As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...

Im Focus: Locusts at the wheel: University of Graz investigates collision detector inspired by insect eyes

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.
