How Long Will My Cartridge Heater Last?
There is no standard heater life in the industry. The life of your heater is affected by:
- Application
- Application Temperature
- Watt Density
- Cycling
- Hole Fit
- Contamination
How Can We Extend the Life of Our Cartridge Heater?
- The number one cause of heater failure is contamination.
- When foreign substances enter the heater and carbonize, this causes arcing and failure inside the heater. If temperature or other circumstances prevent you from using an end seal, avoid substances that could enter the heater at the lead entrance.
- Heat transfer compounds, especially grease based ones, are a common source of contamination.
- Wrapping tape around the lead wires is another common source of contamination as the adhesive melts and runs down into the heater. Remember, any organic or carbon based product has the potential to cause contamination.
- Excessive cycling is the next most common cause of failure. Avoid excessive cycling by properly sizing your heater and not using more wattage than necessary.
- Solid state controllers are also easier on the heaters than simple on-off controllers.
What is the Maximum Temperature for Our Cartridge Heater?
- Maximum exposure temperature is 1022° F (550° C).
