Gas catalytic infrared emitters convert natural gas or propane into medium to long wave infrared by using a special platinum catalyst. By-products are water and carbon dioxide.
This flameless catalytic reaction takes place at emitter surface temperatures of between 175°C and 480°C. The radiation intensity is infinitely variable between 0% and 100%.
Infrared heat transfers energy without contact and generates heat where it is needed. PLC-controlled infrared ovens are precisely adjusted to the thermal process. This improves process stability and quality, increases capacity and saves space, time and energy. Compared to conventional systems, process times can be reduced by up to 65% and the required space by up to 50%.
The emitted radiation is in the range of 3.5 to 5.5 µm and hence exactly matches the absorption spectrum of powder coatings and water.
Gas-catalytic infrared systems are especially suited for some applications, e.g.:
- Painting of heat-sensitive substrates such as MDFs
- Powder coating (metallic and non-metallic substrates)
- Drying processes, e.g. paints, food etc.
- Deep-drawing of plastics
Emitters are available in ten standard sizes that can be combined to form larger emitter units for any application. Each system can be split up into any number of zones for precise control.
- Surface temperatures 175°C to 480°C
- Maximal covering power about 20 kW/m²
- Flameless reaction
- Even heat distribution
- Intelligent control
- Emission of CO2 and H2O
