PTC Thermistors as Heaters has the following advantage, compared with other heating elements:
- No overheat, Safe through temperature limiting characteristics.
- No danger of fires since there are no glowing parts.
- Dynamic, self regulating, and therefore energy efficient.
- No excess temperature protection required.
- Voltages from 6V to 480 V; special voltage applications up to 800 V.
- PTC thermistor surface temperatures can be set from 50C to 320C.
- Compact design.
- Long service life.
