Gas catalytic infrared ovens are very well suited for powder coating. However, if the powder settles on the heating panels, they will stop working properly.
Therefore, it should be ensured that the powder only gets to places where it is supposed to go. If a panel is dirty, it must be replaced.
2. Wrong ventilation
The gas catalytic process requires gas and oxygen. No pressurized air is needed, but if too little air reaches the heating panels, it can result in a decrease in performance. A guideline: 1m³ air per hour per 1 kW of thermal power.
3. Skimping on preheating
Gas catalytic heating panels require pre-heating to start the actual catalytic process. It is not a good idea to save here and to operate the preheating with too low voltage.
The heating panel shows which voltage it needs - and you have to adhere to it!
4. Not paying attention to the type of gas
Gas-catalyzed infrared systems are usually operated with natural gas or pro-pane. These gases have different characteristics and therefore require different-ly designed heating panels to ensure optimum heat transfer. For both types of gas we offer heating panels, you can find out which type you need beforehand.
5. Not using the know-how of our application experts!
Only if a gas catalytic infrared system is perfectly adapted to the product and the process, the heat process will run optimally. In order to improve the quality, stop energy consumption and save costs, it pays to get Heraeus Noblelight applica-tion specialists on board at an early stage.
