Gas-catalytic infrared emitters convert natural gas or propane into medium to long wave infrared by using a special platinum catalyst. The only by-products are water and carbon dioxide.
This flameless catalytic reaction produces controllable surface temperatures of the emitters between 175 ° C and 480 ° C without the release of NOx gases (nitric oxide and nitrogen dioxide) or carbon monoxide. The radiation intensity can be varied infinitely between 0% - 100% of the available output.
Infrared heat transfers energy and generates heat where it is needed. PLC controlled infrared ovens are precisely designed to match the thermal process application. This saves energy, improves process stability and increases capacity and quality. The process time can be reduced by up to 66% and the required space by up to 50% when compared to conventional systems.
The emitted radiation is in the range 3.5 to 5.5 microns and thus exactly matches the absorption spectrum of powder coatings and water.
Gas catalytic infrared radiation is ideal for several processes:
- Coating of heat-sensitive substrates such as MDF
- Powder coating metallic and non-metallic substrates
- Drying processes for example lacquer, food, leather etc.
- Thermoforming of plastics
The heaters are available in ten standard sizes that can be combined to create large or small oven systems depending on the application. Each system can be split into any number of individual PLC controlled zones for precise process control.
